Mix different lights to get custom color temperature.

I have a couple LED photo lights that top out at maximum 5600K color temperature. Other photo led lights at 6000K.

I want to make use of some overhead fluorescent fixtures that use T8 bulbs to increase ambient light. Only 6500K and 5000K bulbs are available on the market.

Could I use (2) 5000K and (1) 6500K bulb in a fixture to get near 5600K ambient light color temperature?

I have tried something similar and wasn't happy with the results. It was difficult to diffuse the light enough to mix the color temps evenly without losing power.

Depending on your needs and how particular you are it might work though.

Why not simply get bulbs of a single color temp, and then shoot RAW and then color balance during post?

I did this sequence to illustrate for you...

1. shot under 2900K CFL
   
2. shot under 2900K CFL, then color balance with Lightroom
   
3. shot under 4000K LED
   
4. shot under 4000K LED, then color balance with Lightroom
   
5. shot under sunlight
   
6. shot under sunlight, then color balance with Lightroom
