I built this LED array for my 5 gallon nano tank. Based on my calculations I get around 1300 lumens of light for less than 1 watt. I built this using 90 10mm white 110000 mcd LEDs and some 110 ohm resistors, and I am powering it with a 12 volt power supply I picked up for less than $2.00 at a computer surplus place (weirdstuff in Sunnyvale).

My biggest concern is that this will be too much light!

Here is the wiring:

I was initially going to paint the inside of the hood white but because these LEDs are very directional I didn't need to. Here is a straight-on view (dang that's bright to look at):

And in the tank (when I get it planted, I will post more):
