When i ordered LEDs to replace some of my whiter (10000K) whites i ordered some reds (~660nm) too... I planned on 9 3W red LEDs on each heat sink, but now that my actual lights are populated i have left over 10000K and 4500K whites. I wonder how much overkill it would be to add 4 of the 4500Ks to the 9 reds on each sink? It makes a nicer 3, 2, 3, 2, 3 pattern on the heatsink (5.9 x 7").
Main reason i want to go LEDs is to save space, as i can't really get into my sump anymore with the big reflector cones there.
