Here is what I did....
There are 6 LED's across the middle of the canopy.
(55 gallon tank)
The specs are....
The LEd's are 3.7V / 20mA / 2600mcd
They each have a 100 Ohm Resistor Soldered to them.
I then heat shrinked and "tied" them into a 6VDC/300mA AC-to-DC Adapter which I bought from Radio Shack.
I know this doesn't tell you a lot but if you have questions please feel free to ask.
