50W China Leds

[bayondai]

I put this in the DIY section too. I wasn't sure where to put the question.

I am thinking about trying one or two of the China 20W or 50W China Leds over my 45 cube as the main lighting for lps softie tank. The tank is 24x24x18 high. Has anyone tried these before? I have the regular 3W crees on my 125, but wanted to try these out. How many 20W or 50W would I need?

I would get the 120w fixture for a tank of that size. I got mine from aquariumleds.com 160 bucks shipped.
