just happen to find this thread while searching google, and wanted to let you know i built an LED light hood for my 90 gallon tank. I didnt use very good LEDs because they were in strips but i used a total of 354 LED's all mounted in an all aluminum hood i fabricated in my sheet metal shop. I think the total cost was around 200 but i think it turned out great!.
