Here is a less powerful LED panel than one based one HPLEDs. This is one I just finished for a turf scrubber. It uses "super flux" LEDs which need 100mA rather than the 350 to 1000mA Soundwave used in his nice setup.

These could work for a shallower tank. I wouldn't try to use this style LED for a tank deeper than about a foot. One of the benefits is no cooling issues the LEDs have radiators built in. You can just use resistors for current limiting. No current drivers! But of course they are not as bright.

Since this is for growing algae it's just red and blue LEDs I used no white units.

Here I'm routing the copper clad board to create the required circuit traces. (I'm amazed the camera stopped the router chuck since it's turning 23,000rpm!)



Here's the stuffed panel. A lot of soldering. 100 SFlux reds and 48 blues. Whew!



Here it is lit up.
