I had a 2g freshwater planted tank running on LEDs, they were only the 8000mcd LEDs, and I'll tell ya 12 of them lit up the tank way better than the 2 13w pc's they replaced...
I just finished testing out some 20,000mcd LEDs (from LKCWTC on ebay), ordered 100 more - for the new 5g nano for my desk at work. Nice color, probably in that 12-14k range.
Just trying to come up with a good way to mount them - was going to install them in drilled acrylic - but then I realized - acrylics a very good insulator - and heat is an LED's biggest enemy... So I'm trying to find another more elegant solution.
