8000-20,000k
6500 k daylight
4000 k cool white
3500 k
3000k halogen white
2700 k warm white
2000-2100k-hps orange
-
65K for me!
-
10K
-
6500k

Lately I've been converting to 5000K full spectrum fluorescents (Duro-test Vita-lite and Sylvania Design 50) but still keep some classic cool whites around.
BTW....don't forget about the 3500K 'white'....used on some of the earliest lamps and still used today but with triphosphor instead of halophosphates.
-
@don93s thanks,for pointing that out.
-
Also 14K is awesome!
-
About 5000K, The light from these tubes (http://www.lighting-gallery.net/gallery/displayimage.php?pos=-19037) is nice.
-
I have to agree! I have a set of C50's in F20T12 ecojunk but they still work perfectly!
-
4100K
Any of them. I don't care of they have crappy CRI, if the general color temp is 4100K, it's perfect. Long live cool white!

2700K and 2100K Golden color ,and warm White, Bright daylight colors give me headaches. :(
-
@nineaclock so anything above 4000k gives you a headache?
-
does anybody prefer low pressure sodiums yellow light.
-
I do along with any other color temp!
-
I like Cool Green! What's the color temp?
I also like Westy Supermarket White, 4500K I think.
4100K is my favorite.
-
color temp of cool green maybe 5700k.
-
@nineaclock so anything above 4000k gives you a headache?
Anything above 5000K sometimes does. I prefer very warm colors. Sodium lamps or Incandescents.
-
2K is also great!
-
high pressure sodium is ok.the median color of hps is 2000k it can be as low as 1900k or as high as 2100k.depending on the mfg.
-
Ya I like 1900K but Sylvania sales nice HPS lamps that have a Golden Crisp color. My 250 HPS flood puts out that color range. I used to have a White Son in the fixture but it never worked out. The rest of the house is Incandescent bulbs and some 2700K CFL.
-
4100K and colored tubes!
-
For me it depends on the use, and the fixture, but I have definitely noticed I gravitate toward higher color temperatures. Almost all of my linear fluorescents are 4100K, as that is the "classic" color for them that I grew up with, so I think that's my favorite color. I also prefer that for metal halide lamps.
For working, I definitely prefer 4100K. For working in the early morning when I'm still sleepy, 5000K or higher helps more than caffeine. For relaxation/casual lighting, I prefer 2700K CFL to incandescent (more of a purplish/greenish hue due to the mercury lines I guess). HPS is also good. For late night partying, my favorites are clear mercury & black light.
I dislike the 3500K fluorescents in my office, and prefer just the window with sunshine wherever possible.
-
i also tend to gravitate towards higher color tempatures with 4100 and 6500 k bring my favorites,i also dont mind something as high as 10 or 20 k.
-
I like 4100 to 6500 for fluorescent indoor task lighting,I don't mind what temperature colour is used for outside lighting.

i prefer mercury vapor and metal halide(ceramic of course)to be used outside,i tried to use high pressure sodium,it was aright but it started murdering my trees and grass,so i switched back to mv.
i think good tempatures for the outdoors would be.
2700-3100k
3900-4100k
6500k
and what would be really intresting,would be to see a street lith with 10-20 k metal halide lamps!
-
4100 K is my favorite for task lighting.
6500 K is too bluish, 3500K & 3000K make things look yellow & dull!
My entire house is lit with 4100K CFLs and linear fluorescents!
-
4100 K is my favorite for all purpose lighting. The light from 4100K
fluorescent tubes blends well with the light cast from a DX mercury
lamp!

i read an article about cfls and it says that you should buy cfls with color tempatures that compliment the colors of the room.
the first cfl i bought was a two pack of general electric 6500k 10 watt cfls,,since it was my first time being exposed to the color,it took me three weeks to get used to the blue color,because i was used to incandescent bulbs.
-
It definitely is an adjustment to get used to the far reaches of the color spectrum, when you are accustomed to either one end or the other. For example, I used to have 3000K CFLs in my room, but thought that they made everything look yellow and dull, so I switched to 6500K. As a result, I experienced the same thing--it took time for me to get used to the new color temperature. However, now when I am in a room lit with 3000K or 3500K lamps, it bothers my eyes, because I'm used to bright, bluish-white light!
Regarding LPS lighting--it is my second favorite HID lighting source, the first being MV!!! I especially love that beautiful red neon glow when it first starts up!
-
i like all hid lamps with mercury vapor being my favorite. ;D
-
3500K & 3000K make things look yellow & dull!
I have 3000k and 2700k lamps all over. They are a nice temperature - although I have found a way of getting them to look like 6500k+, if only briefly!

getting thwem to look like 6500 k breifley,what do you mean.
-
Very simple.
All I have to do is light the room with HPS - and then switch over to the CFL's. For a minute or so they look a much higher CT than normal!
-
ive actully grown fond of high pressure sodium,and i like it a little bit,but i still prefer mercury vapor.
btw intreasting experiment sparkie.
-
it depends on the application of the light. like for closets daylight is best because of color rendering. in bathrooms cool white or warm white is best.
-
With my experience in fluorescent lighting, I can say that cool white can be used in most applications. Warm white tubes do a softer light and give a great result with indirect lighting. Daylight is great in condition that you don't mix it with other color temperatures as the daylight will appear too bluish. Same thing with Warm white...
-
yeah,i wonder why cool whites are most common,as far as Compact Flourescent's go 2700 K is more common,warm white and daylight tubes are rare here!
-
I have two cool white CFLs and three daylight ones. For the soft whites I have too many to count. ;D (Only the CFLs with built-in ballests.)
-
Someone very recently posted in another discussion (I think it was Vince) that you can
mix Warm White with Cool White and Cool White with Daylight, but not Warm White with Daylight. I've found this to be true myself. I find that everything looks sharper under Daylight and Cool White; my eyes are very used to those color temperatures. If I go into a room that is lit with Warm White lamps, my eyes actually start to hurt, and everything looks yellow to me! I guess in my case, I like colors that are more intrinsic to fluorescent lamps (which is partly why I like fluorescent lighting) than colors that attempt to replicate incandescent light.
-
Brian: It was me indeed ;D Soft white fluorescents are (almost) only good for indirect lighting, I wouldn't see something else for that and yeah for direct lighting it's kind of glary. Daylight is pretty hard to mix with other color temperatures, even with cool white it looks a bit bluish, not as much as with warm white. If you add the 3500K you have a lot more possibilities.
-
For me, the only warm white sources that don't hurt my eyes are incandescent bulbs and warm white deluxe fluorescents. The "soft white" compact fluorescents keep bothering my eyes, no matter how much I try to ignore them. They're just awfully glary. I guess it's cuz of the triphosphors used in CFLs, triphosphor linear fluorescents also bother my eyes. My favorite color temperature is 4100K-6500K, clean and crispy :-) Although I admit warm colors can make certain applications look cozy.
-
i generally will use all Color Temps for CFL's...but it is advised that you pick a color tempature that makes the colored objects in the room stand out...the most common color tempature by far is 2700k,3500-6500K Cfls are limited locally where i live..
-
2700-3000k indoors, 4100k Outdoors, And still incadescent are still the best light source out. When it comes to MERCS, DX coated puts out more lumens and I prefer them over clear however I still like clear and will use them.
-
DX Mercs also have a Faster Rate of Lumen Depreciation,because of Deterioation of the phosphorus...but still the cool white light they produce can almost blend in with 4100k flourescents compleatly.
-
I like 4100K or residential, I also like cool white.
-
Anything but warm white. I've used as high as 20,000K.
-
I use colour temperatures from 3000K to 6500K for linear tubes. My favorite from the range of lamps that I use is 4100K and 5000K (preferably with a high cri for both).
For CFLs I like using lower colour temperatures(2700-4100K), I would say my favorite for CFL is around 3000-3500K although I also like 2700K and 4100K CFLs. The higher ones seem too glary to me even though I like them for linear tubes.
-
Daylight (6500K)
I hate 2700k cfls more than anything else :P
-
I would like to have Cool White CFLs (4100K) in higher watts form.
So far, I have couple of 13 Watters so far... :D
-
I like all but especially GE residential light, whatever the color temp that is. Love 5000k but think warmer colors are more natural.
-
Depends on the application to be honest!
Kitchens or workstations etc I would tend to light with daylight, preferably full spectrum tubes. Bedroom however would be warm white (currently it's lit by a mixture of a 3400K Philips CDM-R uplighter and GE Polylux XL colour 830 fluorescents. The actual ceiling light is just a generic 827 CFL as are the norm over here, though it doesn't get used often. There's also an F100W/635 tube propped up in the corner for if I need serious amounts of light for anything. I'd really like that to be daylight, but F100W 8-foot tubes don't appear to be available in daylight any longer.
CFLs over here over 3000K are virtually impossible to find in general stores, none of the local stores around me have any standard fluorescent options other than warm white and white, though one was able to order daylight on request.
I've recently discovered that some of the Philips LED retrofits in warm white have a very pleasant spectrum for areas like bedrooms, with a very warm light, seemingly even more so than tungsten.
-
I like Duro Test's Vitalite at 5500K. Their Optima 50 is a much nicer 5000K than GE's Chroma 50 and Sylvania's Design 50 AND Phillips' Colortone 50. For warm the SP-35 is good and in a 15 watt T8 it's the brighter than anything except a Phillips K&B at 1000 lumens and the best color correction of any of the 3000 K lamps. NOW, I like Duro Test's Optima 32 which was used for a fluorescent aid for studio lighting in TV stations. I like GE's SPX-50 as that's what they put in our WalMart, but NO one has them here. There's a SP-65 by GE, but IS there a SPX-65. There was never a 20 or 15 watt version of SP-65. As for me NO NO NO NO Cool White. CWX is OK, but I won't use it in the house. Same for the "old" warm white with only a 52 CRI. I do like WWX but you can't get that anymore.
I like the old Daylight, but the CRI on those was not so great, either ....
I do like "Natural" 3700K with a 91% CRI according to GE. Cool Green is good as LONG as ALL of your lamps are cool green. I was in an office that was all cool green and it was very nice.

me i dont care for much 2700k and 3000 range
may bedroom is light with 65k CFL rest of the house is 27k CFLs
and basement is 41 k cool whites F34s
i like 41k to 65k depending on what application of lighting.
-
Nowadays, my preference ranges from 3500k (halophosphor) to 5500k. The 3500 I like for small lamps in livingroom, bedroom, bathroom. 4100-5500k for my workshop, kitchen, and laundry.
-
These days my preference vary a lot, from less then 2000K (underdriven incandescent) to about 6000K (daylight). It mostly depend on my actual mood, so highly unpredictable... :-D
-
I prefer 2700K lamps in fluorescent (827 tubes) or 3000K in high-CRI leds (I've never seen a 2700K high-CRI led, so I prefer the 90-CRI 3000K XP-G led; however I use a 80-CRI 2700K AmbientLED at home).
Sometimes I use some "daylight" old fluorescent tubes for fun, but I remove them after a couple of hours.
I've been thinking about buying a "full spectrum" 5500K fluorescent tube and putting it into a vintage desk lamp.
I hesitate to buy one because:
1) I expect some significant flickering on old magnetic ballast desk lamps;
2) My girlfriend might use it for her artwork but I prefer 827 tubes in our apartment.
-
I really like the high color temps, but it really depends on what mood I'm in, too. I hate 2700K fluorescents and cfls, though, and not a fan of frosted/coated incandescents.
One interesting bit of information relative to this discussion is the Kruithof curve (http://en.wikipedia.org/wiki/Kruithof_curve). Basicly, anything above the center bounded area appears over lit, harsh, and fatiguing, and anything below looks stark and dim.
I have experienced this first hand awhile back when I had 3 23W 2700K cfls in my bedroom ceiling fan, picked up some 6500K 25W lamps, tried them for about 15 min, and took them back to the store for some 3500K instead. The lighting level was low enough to make it look really stark and depressing, even though the lumens and the lighting spread remained exactly the same. High color temperatures need more intensity to appear "right", which is also why SOX lamps appear to be very effective at lighting at such low levels of actual light, as our eyes like less of that range of color temp. The 6500K CFL I have works great in a handheld work light, or close proximity task lighting, but up in the ceiling as a general service light it doesn't do well at all. It's in the basement at home now since a power failure took out one of the cfls down there and it was all I had on hand at the time. Same story...really stark and dim.

I Prefer the warm white colors. The cool white, crisp white, and daylight colors give me horrible headaches.
-
My favorites are 4100k, 6500k, and 3000kh

I was recently in a small meeting room that was only lit by one single F40T12 fluorescent tube (and no window). The flicker was perceptible: poor eyes and poor head!
-
3500k is my favorite.
-
My favorite colour temp are 2680K, 5000K and 6500K, all of them in very high CRI.

Whatever I feel like turning on.
My bedroom is lit by an HPS lamp.

6500K with CRI >90 is the most beautyful light in my opinion.
I really dislike halophosphate 3500K - Already have to deal with 4000K halophosphate lamps. These 4000K's I just use in my workshop where 96" VHO and PG tubes are installed, just because I have nothing else than Cool White :) https://www.lighting-gallery.net/gallery/displayimage.php?album=1595&pos=1&pid=159263
-
Haha.. Easy. Cool White De Luxe at 4300k and vita-lite 5000k. In my main attic lighter that use F80T12 i use in it NOS 1989 soviet 5500k tube.. It gives perfect light :D
-
2700k
-
35k and up
-
My favorite is something in between 4000-6500K. I like cool daylight. There must be lot of light when it seems good. :sfl:
-
1700K LPS light, of course ;D :lps: :sli:
-
Cool daylight is nice to indoor wich I said, but warm light fits to outdoor. And of course I love monocratic color of LPS! :lps:
-
Has to be at least 5000K or higher, but I'll also take the glow of a high-pressure sodium any day.
-
I like the 3000k one.
-
I like that crisp 3000°K Halogen light for when I need to see well what I'm doing. Other than that I like standard warm white ~2700°K, as well as orange and yellow light. The coolest I feel comfortable under indoors is 3500°K fluorescent light (835, not Halophosphate).
-
At home I prefer 3000K or lower at night (CRI 85 or better). I like 5000K High CRI during the day.
-
Well I think my fav color temp has to be 2100k it’s just that warm amber glow that of love
-
My LIFX Mini bulb can go as high as 9000K.
-
I don't mind most colour temps however I use 4000k the most. I quite like 4300k too. Anything more than that looks too blue in my opinion unless the room they are in suits it.
