Actually I was looking at hero-led.com and they had a 100 watt driver and Complimentary white bulbs. If you did that got a good heat sink and supplemented with like 3 blue rails and one of each red and green that light make a good spot for a nano. Than you won't have to limit yourself on your photosynthetic animals. I think the grand total in wattage at least would go up to 250 ish so you could run at half power, get amazing shimmer, and have happy clams. Everyone knows happyclams make a happy aquarist lol.
I could swear fleshy or nonstophoops where discussing an led build. The bad thing about this lighting is the uncharted territory. That and the nonuniforminarianism of our illustrious hobby. What works for one might crash another. I really want to incorporate LEDs into my 75 gallon build (which should be up in the next couple of weeks.) but I don't want to have a million 3 wattbulbs that will punch the first 5" with par and starve the rest. That's why I brought up the high wattage option because that will punch and the others can supplement spectrum. In theory at least...
Which hero-led website are you talking about? I came across a few websites with "Hero LED" in their address, and hero-led.com didn't work.
Also, as far as I know, the three watt Cree LEDs are the most powerful ones out there; they work pretty well according to a bunch of different sources. The main thing is balancing the spectrum in order to get the best appearance and performace; one also has to be careful about overdriving the LEDs thereby shortening their lifespan by a ton.
