Interesting..... I'm really looking for a commercially available premade fixture though. The thing stopping me from taking the plunge with LED's is that I haven't seen a tank running them growing nice red plants.
Like the other poster said. You really need a mixture of different color leds. so that the CRI and kelvin temperature is very close to 100 and between 5500-5900k. It is doable by going the diy route. You can use the diy app at buildmyled.com. I played around with it and was able to create a light source with a CRI of 98 and Kelvin temperature of 5500-5900. I suspect that incorporating a yellow led it might bring that CRI to 100. There is a thread by a member using a fixture by that company. The thread contains photos of her planted tank.
