Does 6500K bulbs have a green tint to you?

6500k should be really blue more than anything as it is the same as daylight, which is blue.
 
It depends on the bulb...not all 6500K or 10000K bulbs look the same. But 5000-6000K is the closest to natural sunlight...the higher the kelvin rating the bluer the spectrum, the lower the kelvin, red becomes dominant....most bulbs in the 5000-6000k range are considered "white light", this is especially true of cool white bulbs which fall into this K range. Many, however, will appear to have a yellowish tint to them because they are strong in the yellow and green spectrums as well.

Here is an interesting link that shows that even though many tubes share the same K rating, they still "appear" different colors.

Personally, the best looking lights, IMO, are Coralife's 6500K Trichromatic bulbs...they have a CRI rating in the mid-low 90's..anywhere from 92-94 I believe.
 
Those charts are very telling. It would appear (as we know from high school science class) that if there is a even concentration of red, green, and blue, than we have a more white light.

I just have a hard time adjusting to the color. Still looks green to me. :D

I'm using Phillips 6500K that you buy at Home Depot for $4 for pack of 2. Firing them with an IceCap 440. Anyone else using these and do they look green to you?
 
I have the exact same bulbs. I got them in the same 2 pack when I got the shop light. I kinda see what you are talking about. It looked so different because the bulb I originally had was very blue. I have been thinking where I could find all the specs on the bulbs, and I finally found the official site with everything. This is the link. We have the daylight deluxe.
 
There should not be a bluish tint on lights that are true 6500 Kelvin.
 
Well, I cured my woes, I had an extra actinic bulb laying around and I put that on top of my tank. It balances out the 6500Ks and makes it look more white. I'll probably just fire up the actinic when I'm looking at the tank though.

Actinic is Blue, 6500K Daylight is White. For real. :)
 
I have a pet theory that the amount of time we've all been putting in under flourescents has retrained us to think of cool white as natural looking. Sunlight seems warm and actinics seem corrective.

I think it would be interesting if a carpenter or ranger or farmer or someone else who manages to avoid flourescents most of the time could weigh in on this.
