I'm wondering if you guys are looking at LEDs for large tanks here or for the nanos that some of you have?
There's an interesting article I came across from back in 2003:
http://www.advancedaquarist.com/issu...03/feature.htm
One fellow is using 3 LEDs to light his nano. Though the tank looked somewhat OK, the conclusion would seem that he should have had close to 250 μE/m2 at the bottom of his tank which would say that he required something like 30 LEDs.
The array that Clearlly LEDs has would seem to be too large for a nano with 200+ LEDs. I wonder if they would consider making custom panels for nanos. Perhaps I'll ask.
All in all, I'm not completely impressed with the site as there is little scientific evidence put forth there. I'd much prefer to hear from a few people who've been using LEDs for a couple of months and get a feel for what they think the viability of this technology is at this point in time.
