Another lighting color (K) poll

[John Sayen]

Hi all,

Redoing the lights in the shop and looking at the cree LS8-80L-40K-10V


They come in both 4000K and 5000K and I'm leaning toward 4000k - both come in at CRI 90

Expensive decision that is a pain to swap so I figured I would poll the experts

Which do you like?

4100 is somewhat practical for folks wanting less expensive, off-the-shelf fixtures like the Feit units I got from Costco. 5000K can be "better" in some respects, especially if photography is involved. I'm very happy with the 4100K in my shop. I have enough of it that it sometimes feels like I'm at the beach. LOL

I've looked at a lot of lights, and there doesn't seem to be a really good relationship between what the quoted and perceived color temperature is, so I pick whatever seems least ugly, and has the brightness. For critical judgement of colors, I take stuff out into the natural light (preferably on a cloudy day.)

I got 6000 for my shop as that was what was on sale at Greenlight. I like how much brighter it is with less fixtures I went from 10 to 8 and spaced them out a little but they are way brighter then the fluorescent ones.

I noticed the same thing. I'm not sure if it's the 'quality' of the light or new lamps vs. older lamps. Both Fluorescent & LED lose light output as they age or so I've read. To me, 4K is white, 5K (we just installed 5K lights in our garage) seems slightly bluish.

I have a lot (around 60) of this syle 6500k 105w (400w equivalent) CFL. 24 are in a 1200 sq ft room. I'm really happy with the 6500k color and as my eyes age, the bright light really helps me see.

3K K for me. Hate the blue lights and the way they make everything look weird.

FWIW, there was a tremendous difference pre- and post- cataract replacement lenses. I discovered while I had only one eye each way that the world was amber on one eye and blue in the other. I was very surprised at the striking difference.

I just recently replaced the 10 8' T12 lights in my shop with 8' 5000K LED lights. The improvement was incredible. I love them.

I had lens replacement surgery and found the same thing. Apparently, your natural lens gets amber over time which gives an orange look to things. When they replace your lens you go back to real color vision.

One of the things I like about the 4100K lamps I use is that they are a little truer for color representation without being as harsh as 5000K or higher. 3000K is too warm for color rendition, IMHO, but that's certainly a subjective things for any individual if you take away any technical arguments.

[Leo Graywacz]

5900K for the main shop CRI 93 and 5000K in the spray room. T5 54 HO

I went with 5000k's, work great compared to the old florescents. I was shooting for a sun light as opposed to a cool white, as far as I can tell that's what I got. Probably be best if you could see both colors side by side, which I couldn't do so I took the vendors word for it. FWIW, CRI is marked as 80+.

I went with Phillip's T8 bulbs in mine. 2000 lumens each bulb. Bulb color is 5000k. Color rendering index is 98. Fir me, 4100k is just barely too yellow and 6500k is way too blue. I found 5000k, cri 98 to be perfect for me.

Those are the lamps I use and am very happy with them.

Whatever YOU like. I'm using cheap HF shop lights to replace my 8ft fluorescent fixtures. I can buy one for about what one bulb costs now. And I hate fluorescent lights.
