If I had a blue light that was in the 465-475 spectrum could I Use these instead of actinics and would my corals still be able to flourish if my T5 light were all 10k? I am thinking of using 6 48" T5 10K bulbs and 200 high output LEDs for my blue. The spectrum for the blue LED is in the 465-475 range. If there is not enough blue I can add more LEDs and increase flourescence and if there is to much I can put them on different switches to control the amount of blue. I dont have the ablility to run exclusively LED or should I say I dont have the funds to buy an LED fixture, but the individule LED bulbs in the blue spectrum are affordable and very bright. But I am not sure about the spectrum of these bulbs for growing corals. Thanks in advance for all the input, Les
