How much light is best?
Which of the following is the best lighting scenario for an office environment?
See results without votingLighting Policies in the Workplace
Office managers and company officials of assorted ranks are often faced with making decisions regarding lighting in the office space. Lots of opinions are bounced around, but frequently decisions are made based on misinformation or even just someone's opinions because he or she happens to be the one in charge. In light of recent events in this author’s experience, reasons were given for imposing a policy that insisted all lights in the office be turned on that included OSHA as a primary justification, and that “bright lights will make everyone happier and more productive.” This decision was obviously meant to be in the best interest of the company, but it met with many complaints, and even a few instances of very intense emotional opposition. One person was so upset she didn’t even come to work the next day. Some people were happy with the decision and even called those who favor a much darker workspace “cave dwellers.” It seems very likely many companies have had lighting issues with their personnel about which decisions are made with the justification of OSHA regulations and improved productivity beneath brighter lights.
What follows is an analysis of these two concepts compiled after careful reading from numerous academic, governmental and industry sources including a detailed lighting experiment carried out by the Light Right Consortium, managed by Pacific Northwest National Laboratory and contracted by the Rensselaer Polytechnic Institute’s Lighting Research Center and the National Research Council of Canada Institute for Research in Construction (NRC-IRC), along with several other academic inquiries involved with lighting, its effects on productivity, psychology and mood. In addition, the actual documentation from OSHA has been carefully reviewed. The findings of this research have come to the following three conclusions:
1) OSHA does have a minimum standard for office environment and lowers it even further for workstations.
2) There is no uniform lighting level to optimize productivity, and while lighting levels do correspond to individual productivity, they do so on a highly variable and individual basis.
3) Non-daylight lighting can have negative impacts on business in three key areas including emotional/psychological issues involved with human neuro-biology and physiology; financial implications due to heat generation as well as energy consumption and environmental factors; and productivity/profit.
OSHA on Office and Workplace Lighting
To begin, OSHA has set forth a standard of thirty (30) foot-candles as a minimum lighting requirement for “office” space (United States, Illumination). For clarification, Webster’s defines the term "foot-candle" thusly, “A foot-candle is a unit of illuminance or illumination, equivalent to the illumination produced by a source of one candle at a distance of one foot and equal to one lumen incident per square foot” (“Foot-candle” 746). The OSHA chart has been reproduced below, and can be quickly viewed HERE.
The rules are clear regarding where and when illumination is required and how much, including thirty foot-candles for an office environment. However, OSHA has appended this standard by creating a separate guideline for workstations (seen HERE). In this document, OSHA sets for the guidelines as follows, “Generally, for paper tasks and offices with CRT displays, office lighting should range between 20 to 50 foot-candles" (United States, Computer). The softening of the thirty foot-candle regulation indicates recognition on the part of OSHA that in the actual workspace, there is less need for brilliant lighting in some cases. This is not merely supposition, as that particular document begins with the acknowledgment that environmental factors do have an impact on productivity, and even link “comfort” with “productivity” in one line (United States, Computer Workstations).
Office Lighting – the relationship between light and productivity
In considering this factor, the relationship of comfort to productivity, there is a vast sea of research making that relationship perfectly clear. In the extensive experiment conducted by the group working for the Pacific Northwest National Laboratory mentioned in the introduction above, this was one of the essential components of their investigation. Ultimately the conclusion they had on this regard was as follows:
Overall, these experiments found that changing lighting installations influenced appraisals of lighting quality, and that people who were more satisfied with their lighting (regardless of the type of lighting they experienced) considered the space to be more attractive, were happier, and were more comfortable and more satisfied with their environment and their work. (Veitch 145)
First, it should be noted that the term “quality lighting” was established and was defined as “the intersection of individual needs, architectural form and external conditions (energy, environment and economics)” (Veitch 146). With that definition in mind, consider the above passage. People that were satisfied with lighting were “comfortable with their environment and work.” Arguments can be made as to whether a company wants their workers to be comfortable or not, but to assume discomfort as preferable seems counter-intuitive. In addition, the use of the parenthetical “regardless of the type of lighting they experienced” gives evidence to the variable nature of preference amongst the people participating in the studies, as there were several different lighting set-ups used over the course of the experimental process.
Variability and Personal Choice
This variability in what pleased whom lead to the conclusion that having personal control over lighting was the best choice for a workplace environment. The essential point was that different people wanted and needed different levels of lighting. In fact, the main thrust coming out of this experiment was to suggest that for optimal productivity, workplaces should consider installing lighting with individual unit controls so that each person had total control of the light levels in their own workstation. This conclusion is supported in the work of Nancy Clanton, a lighting design specialist who speaks internationally on lighting issues and who teaches lighting courses and seminars around the world as well as at the University of Colorado. Clanton writes:
Controls are extremely important in office-lighting design . . . Manual controls give workers control over their individual work environments, increasing user satisfaction and acceptance. Because each person has different lighting-level requirements, glare tolerances, and task performance goals. (9)
Once again the importance of the “individual” is clear, and Clanton emphasizes the idea that “each person has different lighting-level requirements.”
Psychologists have further developed this idea, and have linked productivity to personality traits of extroversion or introversion:
Extroverts generally have a higher threshold for sensory stimulation than introverts do, which means extroverts aren’t as affected by bright lights or loud noises. Introverts tend to prefer less stimulation, and are more affected by sensory input. Introverts also tend to be easily distracted by their senses. Bright lights and loud noises wear them out. In contrast, extroverts are more comfortable in the midst of a 'gong show.' Their performance and mental state may not be as negatively influenced by sensory stimulation.
If you’re an introvert at work, make sure your office or space offers low amounts of sensory stimulation. (Pawlik-Kienlen)
Again the evidence is clear in support of the notion that different people have different light requirements, and this documentation even provides a breakdown as to the who and why that is the case, and even goes on to illustrate why some people are going to be more productive in a much lower light environment than others. There simply is no one-size-fits-all lighting level. The experts are in agreement that the best situation for the workers is to be allowed to determine what lighting suits them best individually.
Other Benefits of Lighting the Workplace Right
Positive impact on the satisfaction and mood of workers is not only advantageous to the workers. The organization benefits as well. Offices wherein lighting is not perceived as being unfavorable by workers are more productive; have higher levels of customer satisfaction from their clientele; and have less employee turnover. Veitch, one of the authors participating in the experiments referenced above, wrote,
Other researchers have demonstrated that satisfaction with lighting contributes to greater environmental satisfaction, which in turn leads to greater job satisfaction and that higher environmental and job satisfaction leads to greater organizational commitment and reduced intent to turnover. Moreover, organisations whose employees are more satisfied show better customer satisfaction and business unit performance [Sic]. (146)
This reduction in turnover and improved productivity is not the only benefit of workers being satisfied that an organization will enjoy. Clanton wrote:
What building owners, developers, and employers do not realize is that maximizing daylighting [Clanton’s term for use of windows and sky lights for natural light], installing suspended luminaires, and giving employees control over lighting raises user-satisfaction levels well above 20 percent. Considering that employee salaries are close to $90 per square foot per year, while lighting and control first costs $5 to $10, improving visual quality is a safe investment. (9)
Not only is she championing the benefits of individual controls here, she is even suggesting that spending money to improve lighting by installing personal controls (and “daylighting” which will be addressed a bit further down), is worth spending money on if those controls are not already in place. Now it is not the intent of this article to propose investment in lighting controls for all companies, but it is the intent of the document to suggest that mandatory maximum lighting may not be in the interest of maximum productivity. The evidence supports allowing individuals to control their light-spaces as much as possible to accommodate the highly divergent nature of personal preference, which translates to individual productivity.
Both videos (above and below), while disussing home office, examine elements of lighting that pertain to office and work stations in general.
Light can even be fun!
Psychology, Physiology and Less Tangible Things Are Affected by Workplace Lights
Personal preference is obviously a key and almost random seeming factor here. Where some prefer bright light, others prefer to work nearly in the dark. Very few people like glaring florescent lights. Un-natural lighting (as referenced in opposition by the term “daylighting” above), particularly in large amounts, is counter-productive to the workplace and to human physiology. This is partly due to psychological and biological reality. In his article discussing the color variability in light, Jeff Sauer writes:
Many people tend to find that the warmer white light of tungsten creates a more pleasant environment than the colder light of an office environment. Although in either case our brains do a good job re-establishing our own internal white balance, thereby creating a new reference by which we judge a healthy face or edible fruit. (19)
Clearly what is at stake here is the very ability to recognize the recognizable. Communication is at stake, implicated by the suggestion that we judge “healthy faces” and, by reasonable extrapolation, the expressions thereupon. This is verified in Clanton’s work as well. She writes, “Directional light from parabolic troffers creates uncomplimentary lighting for people’s faces. Because non-verbal communication depends on realistic facial views, the parabolic effect can be disastrous [Sic]” (9). “Disastrous!” she says. The very nature of communication is at stake. Good communication is essential in a workplace, and too much un-natural light actually puts that at risk. Too much un-natural light impacts how we understand each other and how we interpret our environment. Going back to the latter part of Sauer’s comment regarding “recognizing edible fruit,” the impact of un-natural light actually works on deeply rooted, primitive parts of our cognitive process too, invoking the pre-historical, early formative portions of our neurology, bringing in how we locate ourselves in the familiar and the safe. And while Sauer writes that we do a “good job” of “re-establishing our own internal white balance” this does require that people actually make that unnatural adjustment. Human history is one that took place primarily beneath the sun and for tens, if not hundreds of thousands, of years by fire light. It is no accident that the natural light of fire is used in spiritual ceremonies across religions around the globe. Naturally occurring light is comforting. Artificial is not. Massive amounts of artificial light can be even more uncomfortable, particularly for some.
Beyond the Human: Cost and Environmental Impact of Office Light
In addition to the human elements of lighting, and the obvious productivity issues that unpleasant lighting conditions create, there are other costs associated with lighting as well. According to Paul Walitskey, the North American Environmental Affairs Manager for Philips, “Lighting consumes about 40-50% of energy use in a typical office building” (3). Obviously companies with large rooms filled with Internet servers or other variables will have different percentages, but nonetheless, this statement suggests that the costs involved with lighting are extremely large and not something that should be ignored. Given this, any reduction of lighting that falls within legal standards should be considered as a means of saving money. An example of this would be the lighting above the marketing department at this author’s workplace. Four fixtures are mounted above that area, primarily over one cubicle. According to OSHA, “A standard florescent light fixture on a nine-foot ceiling with four, 40-watt bulbs will produce approximately 50 foot-candles of light at the desktop level” (United States, Computer Workstation). If OSHA standards want thirty foot-candle minimums, and actual workstations only require twenty foot-candles of light, this particular cubicle is getting approximately two hundred foot-candles of light. That is TEN TIMES the amount specified by OSHA. Not only might that much blinding glare be unfavorable to the individual working beneath that luminous onslaught, it is costing the company ten times more to light that area than the company needs to pay. This factor can be multiplied out across the office space, mediated, of course, by personal preference in such cases wherein certain individuals may favor more light. In those cases, while the light is costing more, remember what was said earlier regarding “improving visual quality is a safe investment” (Clanton 9). In instances of preference for more lighting, the cost is justifiable as that individual’s productivity will, according to the data, be higher for his or her being comfortable in that work environment. The point is that any reduction in lighting is a reduction in cost, not to mention a reduction in energy consumption as well. “Even a reduction of 100 watts is going in the right direction,” says George Milner, the senior vice president of energy, environmental, and governmental affairs for a large paper company after his plant underwent a massive process and equipment evaluation to reduce their carbon footprint and energy expense (qtd in Mitchell 24). Productivity and profits are improved on the macro level by micro level adjustments across the board.

Office Lighting Policies Should be Flexible
In conclusion, the data and research suggest that having a mandatory maximum lighting throughout the building may have negative impacts on productivity and therefore profit. The evidence suggests that allowing people to select their own lighting levels based on some unquantifiable factors, but factors that are rooted in primal processes of physiological and psychological origin, is the most efficient route for a company to take short of actually investing in advanced lighting processes and designs. By allowing the lights to be on or off by departmental and individual preference, not only is overall productivity to be at its best, there will be less employee turnover, better communication amongst the staff, a healthier environment and lowered overall company expense. Furthermore, no OSHA violations are put in play with the lowered lighting so long as the workspace lighting does not dip below twenty foot-candles. If verification needs to be done regarding minimums, a process for determining this is simple:
Foot-candles can be easily measured and calculated with the use of a (manual) camera equipped with a built-in light meter. With the film speed set to ASA 25 and the shutter speed set to 1/60th of a second, focus on a sheet of white paper placed in the area where intensity is to be measured. Adjust the f-stop for proper exposure. Each f-stop has an approximate corresponding foot-candle reading. (“Foot candle” 2)
Short of violating actual OSHA standards, it is the recommendation of this author that policies of mandatory maximum lighting should not be enacted. Such policies, while perhaps well-intended and founded on a belief that the more light there is the more productive an organization will be, are not supported by the facts.

Very good stuff. It's something that is taken very seriously in TV, in set lighting, where you have to look after luminance to within a few percent. Fortunately, in Europe, we've abandoned the foot-candle in favour of Lux. We use Minolta meters that give you luminance and colour temperature together. TV cameras are far less forgiving than the eye and have to be matched carefully on a standard grey-scale chart. But the offices for people are as haphazard as any other industry!
My office cubicle has a large skylight over it. It is pretty bright there and there are also large windows aroud the outer walls of the office. So much so that it is not really even nessisary to have the office flourecent lights on. But during the summer months it can get very bright and very warm because of the skylights. I have found that I do feel kinda sick feeling sometimes and I am not sure if it is the light level or heat. We have put difusion tarps over the skylights to cut down the light and the heat. So we shall still see if it makes a difference. With the cut down light we are using the overhead lights more. I personally dont dislike the bright light, in fact I think I like it more than the darker envirnoment. but maybe my "likes" are not nessisarily best. Your article was very interesting. Thanks for writing it.
Well, light and sound are the raw materials of TV. Doesn't matter whether it's analogue, digital, whatever. We grab the stuff and send copies of it into folks' living rooms. About the red light thing, have you noticed that women in rooms with red lights tend towards extreme friendliness...?
The fluorescent bulbs are getting to me. I like fire light. Perhaps on tuesday I could start a bonfire in the main office or the production room..
HA... Yeah, a bonfire in your cublicle... I bet your boss might not go for that. Because it was so bright under the skylight in my cublicle, I once threatened to fill my cublicle with sand, put in a beach chair and an umbrella and make my workspace a tropical paradise. The boss didn't think it was a good idea. Hmmm.
I am one of your cave dwellers. I like my work illuminated so my eyes don't straink, but I don't need the whole bloomin place lit up like a day at the beach. Funny, just last night I had the TV playing in the background of an old, WWII movie, and whenever they would show these important meetings going on, they were all lit darkly and dramatically. Think Failsafe and Dr. Strangelove, and I thought to myself, you just knew in real life these rooms would be lit up like the inside of a sun lamp.
In depth and detailed. Good work!
I prefer sunlight. Natural sunlight. In fact, if I can't have natural sunlight brilliantly streaming in the windows and lighting up my home or office like a day at the beach then I prefer to work in low lighting with only the comforting glow of my monitor to guide me.
And wow....this was a lot of information to digest Shade. Nice work! :)
i work in an industrial setting with loads of mercury vapor lights for illumination. the building sucks the life out of me. it is bright, artificial and glaring. i like light to be dim. enough to be safe but then use a spot light for specific jobs. i can feel ok about the day when i wake up but as soon as i step onto the shop floor the lights hammer me into submission and i don't want to be there or do anything.
great information. i'm not just lazy or not getting enough sleep. someone other than me thinks the workspace doesn't need to be lit like the inside of a star. thanks!
I'm agreeing with the benefit of good workplace light, which you provided with a quote. Environmental satisfaction really does translate into job satisfaction. There's something about a room with much natural light that makes it airy, and not constricted. Window placement is probably part of it, along with optimising work space. I'm into home improvement, by the way, which is why I found your hub.
Hella comprehensive and genuinely interesting...Being one of those dejected creative introverts, I've often wondered at the debilitating effects of most artificially lit office (and residential) environments. As in, am I the only who cares how this FEELS?
I'm all for anyone who champions individual controls.
I have been in the lighting business for many years. Lighting is a science and an art with it's own vocabulary. Color rendering, color temperature and lighting distribution all affect how we see and how we feel under artificial light. People like being out in the sun but it hurts our eyes if we look directly at the sun. The challange to good lighting is to light what is around us clearly without reflections. It is critically important to keep all sources of light out of our line of sight. Good lighting design reveals the color and texture of the space and allows us to do our jobs comfortably.
I am doing some research because this very issue is creating MUCH hostility at my workplace. Myself and 5 other I work with are "cave dwellers." There is one individual who works in our office one day a week. He has cried OSHA and without speaking with the rest of us who work there full time, they have instituted a strict "all lights on during regular work hours" policy. I'm upset and angry and not quite sure how to proceed. Human resources and compliance decided on this new policy and my managers have taken the position of "be quiet and don't rock the boat." I'm at a loss as my formerly wonderful work environment has been turned upside down in a few short days. Any suggestion on how to deal with this?
I work for a company that is manufacturing a radically diferent approach to lighting. The product line is called Tambient. Check it out and see if it answers some of your concerns. Of course our offices have this lighting system and it is gorgeous.
Awesome hub! Thanks. You Thumbs UP.
Wow Shades we do think along the same lines. I'm a design partner in my husband's interior design business and lighting can make or break an environment when it comes to productivity, health and well-being. As you suggest, it isn't about the intensity of the lighting, it's about quality.
You hit upon the two biggest problems with contract lighting, OSHA's highly uneducated and knee jerk requirements (which are completely archaic and focused only on energy efficiency) and your opening statement-"Office managers and company officials of assorted ranks are often faced with making decisions regarding lighting in the office space". That important decision should be handled by lighting designers who are trained to create a happy, productive space for employees utilizing natural, LED and full-spectrum lighting. Sorry if I'm rambling on and getting preachy, I'm just revolted by typical office lighting as you've illustrated in photos four and five.
Hope to publish my second lighting article next month :)
Thanks for a really enjoyable and well researched Hub!
Very details, excellent info!
Reminds me of an incident years ago in Canada.
I had turned off most of the lights in the computer work-station room to reduce the heat - the air-conditioners could not keep up with the summer temperature and we were all wilting. Everyone seemed much happier without the glaring lights (and marginally, by 2 degrees, temperature drop).
When in walked a senior manager and declared the lights must be on.
You could hear the groans and feel the resentment - it was our work area, yet beyond our control.
I did not realise that office lighting was this well regulated. It is a good thing becuause it can have a major impact on eye strain.
Lighting at workplace is very important factor as it affects people’s circadian rhythms—which can alter melatonin levels—affecting their level of alertness and mood throughout the day.Fluorescent lamps give low-level ambient lighting in large, open indoor areas.
Very nice hub.Keep sharing.
Nice write up there, and yes, lighting completely affects productivity and moods within the workplace.
Strip lighting has been known to cause headaches, though it is economical and the new approach seems to be leading towards the 'SAD' lamps as by using these to create better moods, productivity will also rise.
Thanks for this informative write-up. Good source of information.
As any room in your home, you should always try to add layers of light in your office. The layers of light and light sources should be selected based on the needs, i.e taks lighting, accent lighting, etc.
I bought a house recently with a 440 sq ft home office. Well, actually the office is in the barn, has few windows and has a ceiling height of 6'11". Currently there are just a few table and floor lamps lighting the place. I plan to start using it soon almost fulltime for computer work and proposal writing. How can I strike a happy medium for my desk area and coference room area where I will lay out 100 pages or so of colored pages?
Thanks, Shadesbreath. It will likely be a year-long journey getting it well-lit.
Green Lotus has quite a background. I'll have to contract her at some point.
I never knew there was such interesting research into lighting. I work in an office and the lighting is quite bright, but nothing to complain about.
Lighting's something I've really struggled with at work. I find I get a little lazy about turning on extra lights on cloudy days, and my eyes definitely get tired too quickly when that's the case. It's great to read specifications and tips for how to make my lighting better especially since I work from home so it's up to me to make sure my office lighting is optimum.
I never realised that there was do much science in lighting the workplace. But it does make sense.
I work for a large company, and we moved to a new building several months ago. The extremely bright lights make several people feel ill, and we complained. Now we are told that all the complaining lead to their decision of going by "Osha Standards" and leaving the lights on at all times! This is a 24/7 center and I work at night, constantly getting migraines just about every night. It is honestly the most ridiculous thing I have ever seen. WTF :(
Thank you for your in-depth research on this subject. If we all could appreciate each other's differences, both the light brights and the cave dwellers would be much more productive. Even bosses are not immune to the damaging effects of the 'light ignorant'. Those I supervise actually went to my boss (not me) with comments that my dungeon office made them concerned, citing an un-named study that "proved" low light equated to lack of productivity and depression. The whole thing snow-balled into other perceived issues with management and, although complaining as a group was a sociological high for them, it is now a very hostile work environment for me (the only cave person). So again, even if it is too late for me, THANK YOU for offering solid evidence in the face of absolute conjecture.
Did they ever make a change for you?
I'm one that is very oriented toward bright but 'natural' light and likely experience Seasonal Affective Disorder during winter months (or in a dark work places). My cubicle is moving from what was a comfortable, bright to a very dark area with neighbors that want it kept that way. I completely agree with individual controls of lighting, odors, etc. that doesn't spill over into unwanted neighboring spaces. Does anyone make high quality light that mounts or clamps to the top rail of cubicle walls (my cube has ~5foot walls)? I'm envisioning a discrete looking, single fluorescent fixture or LED strip that directs light downward but broadly onto my cube desk. All I find are reading desk lights which cast small area light or funky spring arm task lights. Thanks for the site. I referencing it frequently!
Very informative Hub. Proper lighting in the workplace is more important than people realize.
Thank you. Great information, and a great main idea... "Choice"
Thank you. Very informative which many people are not following. We have to advise our nearby people or our organization to follow this guideline to avoid electrical, hwalth and environmental hazards.
This article and gathering of information hits the nail on the head for me. The office I work in has turned the over head lights back on, or this one woman who claims she cannot see turned them on. She turns them back on after they have been turned off for over a year. Immediate are the affects of the light, I can hardly focus on the screen. I have anti glare coatings on my glasses and a hat on but the glare is unstoppable. This place is to bright.
I only work from home now under dimmed INCANDESCENTS. What a bloody difference. I can concentrate so much better. Hate fluorescents and hate CFL even more so.
In Australia, Philips has made the requirement for some aspsect of building code so that it must be brighter (yet again). I was talking to a member of gov't and he said that almost every year the stores are getting brighter. What gets me is they BAN the INCANDESCENT and then up the requirement meaning that more light has to be used. Sounds dodgy to me! Come visit Australia. The stores have shiny containers of 2 big CFL per container. Way to annoying light and also have large industrial blocks of way too bright too white halogens. I literally can't stand the shopping centers in Australia. I simply avoid them full stop! All this crap of research - read between the lines: $$$PROFIT$$$. In Australia, the Lighting Association of Australia is responsible for all this stuff. Guess who the two main members are? Philips and Osram! Get it. The INCANDESCENT ban has nothing to do with ENVIRONMENT. In 2003 a study showed no more than 2.5% take up of CFL by Americans. To cut the story short, they banned the winning competition: the INCANDESCENT bulb! That's they only way they could get people forced into the product. It's pure Marketing scam people. Open your eyes!
The Standard Incandescent Light Bulb
What is Incandescence?
Incandescence is the light produced by a heated object. This light contains BILLIONS of frequencies. It is the highest quality of light you can get.
How NOT to save energy:
- Using light source that cause a disturbing effect on people and environment around them. These sources are cold, aggressive, eerie forms of lighting. These include CFL, Fluorescent, and white-LED.
How TO save energy:
- Solar power
- Wind power
- Turn off electrical when not in use
- Use light dimmers (on INCANDESCENT lights)
(Note: Modern light dimmers use a TRIAC and no rheostat (have not heard that word for 20 years or so). They are VERY efficient. I use trailing edge dimmers and these dimmers also slowly turn on the light (dark to dimmer setting in about 2 secs) to further prolong the life of your INCANDESCENT. Do not be fooled by some of the current false news about light dimmers. They are efficient).
The Standard Incandescent Light Bulb
HOW TO STOP THE BAN OF INCANDESCENTS
-If a store so much as starts banning just one kind of light (they will start with 100W first), then immediately email and write to them:
"Since you have banned my choice of light bulbs, I will no longer purchase any items from your store. YOU ARE BANNED.
This ban will not be lifted until all 40W, 60W, 75W, 100W STANDARD INCANDESCENT clear and frosted BULBS/GLOBES are returned to the shelves. Have a good day."
And then get 5 other friends who will each tell 5 other friends to do the same.
-Speak directly to everyone everyday about this issue. Make sure the entire world is saved from this disaster.
The Standard Incandescent Light Bulb
What is wrong with 'efficient lights'?
- CFL / FLU / white-LED give off a light that is simply unpleasant
- Too bright, Too white halogens are also annoying
- In lighting, more efficient than STANDARD INCANDESCENT just leads to very undesirable light
- Do you paint your walls with pure white? or with cold-off-white? I hope not. If you want comfort, you paint with warm-off-white (the yellow and reds). Just like you would choose an INCANDESCENT (reddish to yellowish-white).
- CFL is cold light (you can try to filter it and get 'warm' but there is a reason why this does not work). White-LED is also cold and eerie.
The Standard Incandescent Light Bulb
Why is INCANDESCENT best source of light:
CFL / FLU / white-LED produces about 5 peaks of light frequencies:
(IR) ____I______I____I__I_______I_____I___ (UV)
(graph looks like dead trees with little fill in)
This is terrible light. And it is summed to a BLUE area of light. Very annoying. Very toxic. Hard to concentrate. Uninviting. Unnatural effect
Fire-place Light, Candle-Light, Incandescent-Light has BILLIONS of frequencies
______________________________
###############################\
###################################\__
The area between the top curve and the base is full of frequencies. It is TOP QUALITY light that is created by HEATING AN OBJECT. This is why it takes a bit more energy to get this quality light.
You can dim it and is calm.
Your eyes see RED / GREEN / BLUE differently according to DNA. EVERYONE will see the COLOR COMPOSITION OF CFL / FLU / LED differently due to the spikes mismatch.
Not true for INCANDESCENCE. All FREQUENCIES exist so we see all there is for any combination of human DNA RED / GREEN / BLUE receptors.
The Standard Incandescent Light Bulb
EVERYTHING IN YOUR ROOM is lit by the light you choose. All this light is reflected, refracted, filtered, so on. It lights your ceiling, floors, sofas, coffee table, clothes, pictures, everything. If you start off with bad light you get strange results. Only full-body INCANDESCENCE can deliver the BILLIONS of frequencies required!
Try RED filter on white-LED. Result is odd BLUE / PURPLE / REDDISH. True test of bad light.
Try RED filter on INCANDESCENT. Result is awesome pure RED amazing light!
I strongly recommend only using STANDARD INCANDESCENTS. You can use the 30% efficient halogen bulbs but it certainly is not as aesthetically pleasing due to internal glass and many also have a metal clip. It really is a waist of effort just to get 30% (I have measured 25% on one).
STANDARD INCANDESCENT is far cheaper to produce and extremely easy to recycle.
The Standard Incandescent Light Bulb
Please note that this BAN is NOT really about SAVING ENERGY.
It is a marketing plan as any other. Make the competing product look bad. Make the new product look better. Plant propaganda to make you feel bad by not going for the new product. Nothing new under the sun here. Marketing 101.
Philips wants to push their baby the CFL so on. A 2003 study showed that take up was only 2.5% for Americans who kept going back to the more pleasing light of the INCANDESCENT bulb. So to cut the story short, the INCANDESCENT was banned to further the sale of other lights (Philips, Osram, GE, LED Industry all would like to have more sales).
The INCANDESCENT is our most important form of calm lighting. It is easy to make and recycle. It is easy to hook up to DC and AC and batteries.
The only other sources for this quality light is Fire-place Light, Candle-Light, Kerosene-Lamp Light.
Don't let $$$PROFITS$$$ and $$$GREED$$$ ruin your country.
Example Australia. Now "Hellstralia" for its bad lighting.
The Standard Incandescent Light Bulb
This BAN is ABOUT $$$PROFIT$$$. Trust me. If you put a kink in their profits, they will complain with greater effect than a mere single citizen to Philips/Osram/GE. If they can only make a profit by selling INCANDESCENTS, guess what follows. Its not rocket science but you have to do as I say or it will not work.
I am for all citizens in the world to have the best and most pleasing form of lighting. Your lighting environment effects how you feel and behave. Their is no excuse for bad lighting. CFL/FLU/white-LED are aggressive, unnatural, dangerous, uninviting, hard-to-concentrate-under "Light for the dead" kind of lighting.
INCANDESCENT is calm, inviting, friendly, romantic, warm, comfortable, safe, "Light for the living" kind of lighting.
For God and Country. America (and the rest of the world). Do not let them take about your INCANDESCENT lighting!
You will regret it!
Come visit Australia. I don't travel Australia anymore.
Australia has such bad and uninviting cold lighting everywhere including hotels, motels, restaurants, coffee shops, shopping centers, so on. Even the street lights have a mix of good and horrible white lighting (it only lights the rain, quite dangerous).
Oh sorry, its now called "Hellstralia".
The Standard Incandescent Light Bulb
How NOT to STOP THE BAN OF INCANDESCENTS
-Sit on your sorry ass crying
-Sign up for all petitions (just doesn't go anywhere)
-Write to the government (usually just ends up in the waist bin)
HOW TO STOP THE BAN OF INCANDESCENTS
-Speak directly to everyone
-If a store so much as starts banning just one kind of light (they will start with 100W first), then immediately email and write to them:
"Since you have banned my choice of light bulbs, I will no longer purchase any items from your store. YOU ARE BANNED.

You want efficiency only and trade it for bad lighting? Just visit Australia. A complete wreck of a place.
CFL DANGERS
IMPORTANT SAFETY INFORMATION
Should you accidentally break you CFL (Compact Fluorescent Light),
Please follow these procedures:
Please read these now BEFORE disposing of or breaking a CFL.
Many people have NOT left the room first (you will breathe in mercury
vapor) or have used a vacuum cleaner (spreads mercury vapor).
Prevention
To prevent potential mercury exposure:
* Store and handle CFLs responsibly
* Following cleaning procedure when cleaning up broken CFLs
* Always recycling CFLs (never throw into normal garbage bins)
* Use other types of lighting such as Incandescent Lights in areas
where breakage is likely.
Cleaning Up Spills
What Never to Do After a Mercury Spills
* Never use a vacuum cleaner to clean up mercury. The vacuum will
put mercury into the air and increase exposure.
* Never use a broom to clean up mercury. It will break the mercury
into smaller droplets and spread them.
* Never pour mercury down a drain. It may lodge in the plumbing and
cause future problems during plumbing repairs. If discharged,
it can cause pollution of the septic tank or sewage treatment plant.
* Never wash clothing or other items that have come in direct
contact with mercury in a washing machine, because mercury may
contaminate the machine and/or pollute sewage. Clothing that
has come into direct contact with mercury should be discarded.
By "direct contact," we mean that mercury was (or has been)
spilled directly on the clothing, for example, if you break
a mercury thermometer and some of elemental mercury beads came
in contact with your clothing.
* Never walk around if your shoes might be contaminated with mercury.
Contaminated clothing can also spread mercury around.
CFL DANGERS
Cleaning Up a Broken CFL
Fluorescent light bulbs contain a small amount of mercury sealed within
the glass tubing. When a fluorescent bulb breaks in your home,
some of this mercury is released as mercury vapor. The broken
bulb can continue to release mercury vapor until it is cleaned
up and removed from the residence. To minimize exposure to
mercury vapor, EPA recommends that residents follow the cleanup
and disposal steps described below.
This page presents only the most important steps to reduce exposure
to mercury vapor from a broken bulb.
1. Before cleanup
* Have people and pets leave the room.
* Air out the room for 5-10 minutes by opening a window
or door to the outdoor environment.
* Shut off the central forced air heating /
air-conditioning system, if you have one.
* Collect materials needed to clean up broken bulb.
2. During cleanup
* Be thorough in collecting broken glass and visible powder.
* Place cleanup materials in a sealable container.
3. After cleanup
* Promptly place all bulb debris and cleanup materials outdoors
in a trash container or protected area until materials
can be disposed of properly. Avoid leaving any bulb
fragments or cleanup materials indoors.
* If practical, continue to air out the room where the bulb
was broken and leave the heating/air conditioning system
shut off for several hours.
CFL DANGERS
More details:
NOTE: these instructions also apply to spills from other sources, if the amount spilled
is less than or similar to the amount in a thermometer (see specific information about
how to clean up broken fluorescent bulbs)
* Have everyone else leave the area; don't let anyone walk through the
mercury on their way out. Make sure all pets are removed from the area.
Open all windows and doors to the outside;
shut all doors to other parts of the house.
* DO NOT allow children to help you clean up the spill.
* Mercury can be cleaned up easily from the following surfaces: wood,
linoleum, tile and any similarly smooth surfaces.
* If a spill occurs on carpet, curtains, upholstery or other absorbent surfaces,
these contaminated items should be thrown away in accordance with
the disposal means outlined below. Only cut and remove the affected
portion of the contaminated carpet for disposal.
Items needed to clean up a small mercury spill
1. 4-5 ziplock-type bags
2. trash bags (2 to 6 mils thick)
3. rubber, nitrile or latex gloves
4. paper towels
5. cardboard or squeegee
6. eyedropper
7. duct tape, or shaving cream and small paint brush
8. flashlight
9. powdered sulfur (optional)
Cleanup Instructions
1. Put on rubber, nitrile or latex gloves.
2. If there are any broken pieces of glass or sharp objects,
pick them up with care. Place all broken objects on a paper towel.
Fold the paper towel and place in a zip lock bag. Secure the bag
and label it as directed by your local health or fire department.
3. Locate visible mercury beads. Use a squeegee or cardboard to gather
mercury beads. Use slow sweeping motions to keep mercury from
becoming uncontrollable. Take a flashlight, hold it at a low
angle close to the floor in a darkened room and look for
additional glistening beads of mercury that may be sticking
to the surface or in small cracked areas of the surface. Note:
Mercury can move surprising distances on hard-flat surfaces,
so be sure to inspect the entire room when "searching."
4. Use the eyedropper to collect or draw up the mercury beads. Slowly
and carefully squeeze mercury onto a damp paper towel. Place the
paper towel in a zip lock bag and secure. Make sure to label the
bag as directed by your local health or fire department.
5. After you remove larger beads, put shaving cream on top of small
paint brush and gently "dot" the affected area to pick up smaller
hard-to-see beads. Alternatively, use duct tape to collect smaller
hard-to-see beads. Place the paint brush or duct tape in a zip lock
bag and secure. Make sure to label the bag as directed by your local
health or fire department.
CFL DANGERS
6. OPTIONAL STEP: It is OPTIONAL to use commercially available powdered
sulfur to absorb the beads that are too small to see. The sulfur does
two things: (1) it makes the mercury easier to see since there may be
a color change from yellow to brown and (2) it binds the mercury so
that it can be easily removed and suppresses the vapor of any missing
mercury. Where to get commercialized sulfur? It may be supplied as
mercury vapor absorbent in mercury spill kits, which can be purchased
from laboratory, chemical supply and hazardous materials response
supply manufacturers. Note: Powdered sulfur may stain fabrics a dark
color. When using powdered sulfur, do not breathe in the powder as
it can be moderately toxic. Additionally, users should read and
understand product information before use.
7. If you choose not to use this option, you may want to request the services
of a contractor who has monitoring equipment to screen for mercury vapors.
Consult your local environmental or health agency to inquire about
contractors in your area. Place all materials used with the cleanup,
including gloves, in a trash bag. Place all mercury beads and objects
into the trash bag. Secure trash bag and label it as directed by your
local health or fire department.
8. Contact your local health department, municipal waste authority or your
local fire department for proper disposal in accordance with local,
state and federal laws.
9. Remember to keep the area well ventilated to the outside (i.e., windows
open and fans in exterior windows running) for at least 24 hours after
your successful cleanup. Continue to keep pets and children out of
cleanup area. If sickness occurs, seek medical attention immediately.
View information on health effects related to exposures to vapors
from metallic mercury. For additional information on health effects,
the Agency for Toxic Substances and Disease Registry (ATSDR) provides
a Mercury Fact Sheet Exit EPA Disclaimer that also presents information
on health effects related to exposures to vapors from metallic mercury.
CFL DANGERS
Recommendation: If there are young children or pregnant women in the house,
seek additional advice from your local or state health or
state environmental agency.
Many states and local agencies have developed collection/exchange programs
for mercury-containing devices. Some counties and cities also have household
hazardous waste collection programs. For information about these programs,
contact your local officials to find out when and where a collection will
be held in your area. Earth911 also provides information about local
collection programs. For information on recycling compact fluorescent
light bulbs (CFLs) and other mercury-containing bulbs,
see Recycling and Disposal After a CFL Burns Out.
Note that some states and local jurisdictions have elected to pass regulations
that are more stringent than the federal hazardous waste regulations.
Several states and municipalities do not recognize the exemption for
households; others regulate all fluorescent bulbs as hazardous,
regardless of their mercury content. For example, Vermont bans all
mercury-containing waste from landfills, including mercury-containing
waste generated by households. For more information specific to your state,
visit Earth911.com to contact your local waste collection
agency, which can tell you if such requirement exists in your state or locality.
At site cleanups of active facilities or abandoned hazardous waste sites, mercury
presents significant environmental challenges because it is difficult
to treat, exists in many different forms, is volatile, and can be difficult
to analyze. Some mercury contamination sites are also contaminated with oils,
radioactive materials and organic compounds that present technical challenges.
Cleaning up mercury contamination at active facilities or at abandoned hazardous
waste sites and preparing the land for redevelopment or redeployment happens
in a variety of EPA programs. EPA is improving the coordination, speed, and
effectiveness of cleanups at the nation's contaminated sites through the
One Cleanup Program. This Program is EPA's vision for how different
cleanup programs at all levels of government can work together to meet
that goal and ensure that resources, activities, and results are effectively
coordinated and communicated to the public. EPA accomplishes this work
in partnership with state, local and tribal governments and responsible
parties. View more information about the various cleanup programs managed by EPA:
Please note that the instructions apply to CFLs and Fluorescent tubes and
FS (Full Spectrum) lights (which are Fluorescents).
It also applies to other items containing mercury such as thermometers
and older style thermistor controllers. See links below for more details.
NOTE: These instructions DO NOT apply to Incandescent Lights. They do not contain
mercury. They are also easily recycled and do not pose a threat to the environment.
Note: Above is only a summary. To see full text, please refer to the references

CFL DANGERS
SIMILAR INSTRUCTIONS
From Canada.
Minimizing Your Risk
* Always handle CFLs carefully when installing and removing them.
* Check with your municipality to see if CFLs can be recycled in your area.
Recycling them means that the small amount of mercury they contain will
not end up in the environment.
* If you have skin sensitivities to UV, or have Lupus or another auto-immune disease
that makes you sensitive to UV, you can take these steps:
o Buy CFLs that are marked low UV.
o Buy CFLs that have a glass cover already added, which will help
further filter out UV radiation.
o Use additional glass, plastic or fabric materials in your lighting
fixtures to act as UV filters.
o Increase the distance you are from the CFL,
as this will reduce the level of UV exposure.
* If you break a CFL, follow these directions for clean-up:
o Leave the room
+ Remove people and pets from the room and keep them out of the room during
the clean-up process.
+ Avoid stepping on any broken glass.
o Ventilation
+ Ventilate the room for at least 15 minutes prior to starting clean-up by
opening windows and doors to the outdoors. This will ensure that
mercury vapour levels are reduced before you start cleaning.
o Clean-up Directions for Hard and Carpeted Surfaces
+ Do not use a vacuum to clean up the initial breakage, as it will
spread the mercury vapour and dust throughout the area and may
contaminate the vacuum.
+ Wear disposable gloves, if available, to avoid direct contact with
mercury and to prevent cuts.
+ Scoop or sweep up the broken pieces and debris with two pieces of stiff
paper or cardboard. Do not use a broom.
+ Use sticky tape, such as duct tape or masking tape, to pick up any
remaining fine glass or powder.
+ Wipe the area with a damp paper towel, cloth or disposable wet wipe
to remove any residual particles.
+ Place the broken glass and clean-up materials in a glass container
with a tight fitting lid to further minimize the release of mercury vapour.
o Carpeting - Steps to Take After the Initial Clean-up
+ If the rug is removable, take it outside, shake and air it out for as
long as is practical.
# The first time you vacuum on installed carpet after the clean-up,
shut the door to the room or close off the area as much as possible
and ventilate the room in which the lamp was broken by opening the
windows and doors to the outside. When the vacuuming is done,
remove the bag, wipe the vacuum with a damp paper towel, cloth
or disposable wet wipe, and then place the vacuum bag and paper
towel in a sealed plastic bag outside. In the case of a canister
vacuum, wipe the canister out with a wet paper towel and dispose
of the towel as outlined above. Continue to ventilate the room for
15 minutes once the vacuuming is completed.
o Disposal
+ Immediately place waste material outside of the building in a
protected area away from children.
+ Room with a open doorDispose of the waste at a household hazardous waste
location as soon as possible. Check with local, provincial,
or territorial authorities about the requirements for recycling
and for the location of household hazardous waste depots or pick-up.
+ Do not dispose of the waste in your household trash.
+ For further information on disposal, please contact Environment Canada.
o Washing
+ Wash your hands after storing and disposing of waste.
* Additional Information
o Remove and install the CFL by handling only the base of the lamp to prevent
any unnecessary pressure on the glass that may cause it to break.
o Consider using a drop cloth when replacing a CFL to minimize the chance of
breakage should the lamp fall or to protect the flooring and assist
in clean-up should the bulb drop and break.
o Store fluorescent lamps in containers that prevent them from breaking,
such as in their original packaging.
o Consider avoiding the use of CFLs in areas where the lamps may be easily broken.
Those who have Lupus or another auto-immune disease and certain skin conditions
can be sensitive to the UV from CFLs, in the same way they would be sensitive
to sunlight and other light bulbs that emit UV. If you believe you are suffering
from symptoms related to UV, you should consult your health care provider.
Note: The limits of exposure for Canada are: no closer than 30cm for 3hr or 1hr depending on CFL light.

Wow.
This is exhaustive. Really well done. I kept thinking all through it though that the problem isn't lighting at all but the tendency of corporate entities to apply industrial principles of standardization to office environments and treat office work like factory work--breaking everything down into quantifiable bits that can then be analyzed and adjusted to create increased 'productivity'.
Jesus.
Whatever happened to being able to bring a framed photo of the kid and a potted plant and to be able to count on being treated like a human being instead of a robot or a piece of equipment with corpuscles? Having working in two cube farms for close to eight years, I've witnessed the kind of meltdowns you describe over way less than lighting changes. Those kinds of meltdowns should tell management that more is wrong with their model than just the wattage on the light bulbs.
That entire category of workplace environment needs to be reconsidered. I think it makes people insane.
