Fluorescent lights are pretty bad, and they really do hurt profits, and people don't feel as alert under this TERRIBLE artificial light, attached is the color spectrum of a fluorescent light.

The one that doesn't look completely insane will be daylight. (actually the other picture will be daylight, then all other light sources compared to it, just thought about it like that now).
 
THAT'S why I don't like fluorescent lights.  And the fact that they contain mercury.  And the fact that since they DO contain mercury, NOTHING by "default" has been done to shield them, and they do make shielded bulbs, why are they not right there in all the stores, that really makes me angry.
 
Incandescent bulbs are literally a LUXURY item for sleep, you can dim them perfectly every time, and they are very expensive to run, so you have to have the money to keep them running.  You never thought about it that way before huh?  Well now I do.
 
The second picture is not showing up, I'll give it some time, but if it's not showing let me know.
I really love natural light, just looks a MILLION -- nope, a BILLION time better than ****ty T8 or whatever they use these days, really terrible light pink color on everything compared to the light from the blue sky and that bright orange ball of hydrogen and helium.
 
I'll just paste the second picture so you can see it.
 
EDIT!
http://www.psychologytoday.com/blog/the-athletes-way/201306/exposure-natural-light-improves-workplace-performance
That will show that exposure to light helps performance, so it also makes sense to think FULL truly FULL spectrum sunlight would also improve performance compared to POS fluorescent bulbs.

    Fluorescent lighting is hard on the human eyes, I use LED's myself, and will be doing wall lamps for indirect lighting. Glare is evil.....Most dont even think about lighting placement, its just not the type of light or color temperature....

    Yup, I have no fluorescent lights in my home, all LED's.  Also, our offices just recently moved away from fluorescent lighting as well.

    Awesome, that's a great way to do it!
     
    I strongly recommend Philips LED bulbs particularly the L prize bulb because I think it actually uses a lime green LED instead of a blue LED like I think a lot of others choose to use.

    Haha, you all started replying so quick I can't even reply to them in order!  Thank you!
     
    If you use 5K - make sure they are *EXTRA* bright like a living room area (an example would be ... I don't know the ratings of individual bulbs, but try for 3,000 lumens in total, or even more -- as much light as possible.  Also you could get the cheaper more practical version of Philips Hue which just does transitions though cool white and warm white, so them at night you can really dim things down!
     
    Edit:  3k?  I recommend 2700k or lower because the yellower / more orange it is, the more relaxed you will be at night, there is an immense amount of research that I've linked to before here, and here it is again

    I don't quite understand?  Do you want the amber / actually not really amber, it's a warm white, and it's white once your eyes adjust, you can EASILY get in a19 -- if you mean like an amber / orange color, I don't know if those are made, are you thinking of a really really dim Incandescent orange color?  Another thought, are you thinking or aware of Philips 'Dimtone' bulb that get's even warmer when it dims?
     
    I would really like to help you choose the bulbs that would suit you best!

    While there's a nice break I'd like to steer the conversation / discussion over towards natural light.

    Imagine a store office school or other area that you are familiar with that's currently lit with florescent lights. Easy right.

    Now take a few minutes and imagine that same place with just no lights turned on.

    Now imagine it has a way to bring in lots of natural light through the use of skylights or any other device you can imagine.
    How does it look, how would the skylights be laid out and how many would there be?
     
    Yep, forgot to format it!

    This might be why I feel like crap at work - I'm fully lit by fluorescents - natural light access is past a wall for me.
    Note to self - get more sunlight...

    Absolutely!  Seriously, talk to your boss and tell him / her that you aren't at your best under this lighting from hell.  Think about it, if you feel tired and slow, that's lost profits for them, and all they have to do is AT LEAST go with a BLUER light source (I'll say it again, the "standard" fluorescent lights used have a STRONG pink color to them), so it looks better, but maybe they could add a few windows - I mean who the hell doesn't want / need windows?
     
    If you do talk to your boss, I'd like to know what they say!
     
    Also, if you want to take a break and your boss doesn't really want you taking breaks, even if you're not a smoker (I'm definitely not) I'd suggest taking unlit cigarettes with you, that's why smokers aren't as unhealthy as you think they would be -- they get more sunlight than non smokers, just think about that.  No wonder they like going outside to smoke. 

    I think this will get you about 5 - 7 minutes, but I'm not sure... (I always picture this on top of a roof, way up in the air.... haha, I guess that's not gonna happen for most offices huh? -- edit, I also picture this on a cool morning as well, like the perfect scenario!)

    Our company just dropped $60k on a "smart" fluorescent system.
    I like the crisp brightness and reduction in shadows compared to Metal halides we used to have, plus the lights individually turn off when you leave an area.
    I work under the lights 10+hrs a day, and haven't noticed any alertness issues, (although,  I do work a hairsbreadth away from painful mutilation if I screw up, so I'm constantly hyper alert by habit.)
    Without knowing the actual k-value id estimate them to be around 3500 - 4000k
     
    The only major downside is now we've lost a few of the weaker Fm radio stations...
     
    The LED systems Ive been under all seem way to harsh, and do cast a wicked shadow lines.
    But for the energy savings alone I would have gone LED if it was my choice.

    They say opposites attract. I hope you meet someone who is good-looking, intelligent, and cultured.

    fluorescent bulbs help trigger my migraines if other conditions are already started physically.Ive tried to limit my interactions now for over 2 decades .But i still need a real reason to use as to why im crazy :) This doesn't surprise me at all .I switched bulbs types back in early 2001 when the prices were insane .I have one 15w single 18 inch over my sink (compromise with wife for cleaning dishes )

    Yikes! Just PLEASE go LED and that way no mercury on all your dishes if it breaks, Philips makes a great LED bulb, Cree is 2nd (for not having a very diffused light and you can EASILY see the individual LEDs even in a lamp shade.

    Did you guys seriously not know this? BTW, you do realize the colors on walls and surrounding areas have just as much impact as the light source.
    And Timpster, do you work for Philips or something?

    clo007,

    Yep. Billy the kids was asking about black or dark dark wall colors. Been trying to educate family and friends about, color tones in the home, I like earth tones myself, color and proper temps of you choice lighting and indirect lighting with proper placement.
     
    Same thing with proper ergonomics, lighting in the home, kitchen, just not the desk or office. Just seems like very few care, till its too late.
     
    Edit: Dont forget about aesthetics, to help set what ever moods your looking for. You dont need alot a crap/clutter, or alot od crap that needs cleaning. A few pics/art on the wall, doesnt mean its goes in a frame. A small fish tank even, or adding woodwork to replace that modern crap.

    No I don't work for philips but I have their Hue, and it looks MUCH better than Cree 40w equivalent bulbs, the light for Philips is FAR more diffused, and Cree should really work on that.

    Here, I'll see if I can spike some discussion about natural light.
     
    If you had YOUR choice for where you work / learn, and are currently lit by fluorescent lights, would you choose to keep the fluorescent bulbs, or have sky lights?
     
    Why (as if it's not already obvious)?

    Soon all lights will be newer tech most especially if the new tech saves money.

    Someone get outside more and look at the bigger picture...
     
    My point is, we all don't get nearly enough sunlight -- we're bathed in the terrible glow of fluorescent bulbs and until LED bulbs can provide the *FULL* spectrum of light, like sunlight can, it's just not going to be the same, so why the hell don't we just all let in natural light into our buildings???  I don't understand why that's so hard to do!

    It's exactly like light pollution - if the fluorescent lights hurt performance of workers and students - why not just use what's best and everything is better?

    If you use a computer at night, check out f.lux
    Research: https://justgetflux.com/research.html
    Download: https://www.justgetflux.com/
    This reduces how blue (6500k) the screen is and looks better once you get used to it - the getting used to may take up to a week!
      Your screen will be "more orange" at night but it's for the best. In about 20 minutes your eyes won't even notice.  A white paper should match your screen, maybe play with the monitor settings to get it closer.

    I work in a building with no windows and yes the fluorescent lighting really hurts my eyes after a while. My guess is that no windows makes for a secure building.

    No reason to do defensive Tim. Its an online forums dude, there are certain etiquette as well.
     
    KS,
     
    Yep. Billy the kids was asking about black or dark dark wall colors. Been trying to educate family and friends about, color tones in the home, I like earth tones myself, color and proper temps of you choice lighting and indirect lighting with proper placement.

     
    BTW, it isnt just the bulbs that effect your vision,
     
     
     As well as, aesthetics, adding nature lighting, mood, placement furniture, just not the lighting placement, its not just the type of lighting.
