Question on T5 banks
 

If you are using T5's, do you mix 6400K and 3500K? If so what percent? I'm leaning this way but need a forum opinion. Thanks.

i use 6400k bulbs, its works for me. how big of an area and what are you trying to light?

Not sure yet. Yeah, I knew you were using one kind of light. I just wanted to know if others are using a blend of warm and daylight and how much.

I use 50:50, seems to work very well.

How do you figure the average Kelvin light temperature? If I do a simple average (assuming 4 bulbs - 2ea 6000K and 2ea 3500K) I get about 4800K - a bit on the warm side for daylight. If I figure 3ea daylight plus 1ea warm I get about 5400K - almost the same as average sunlight. Just curious and this is why the original question.

A lot info that I have seen recommends a mix of 3000k and 6500k. I am using equal numbers of 3000k and 6000k (ordered 6500k but got 6000k) I also have some that are called 'Full Spectrum' but have not used any of these yet.
