I made a 10w LED refugium light with an old tablet power supply and some parts I bought on ebay. 12v 1.5A power supply. 10w LED and 12v driver, lens, mounting bracket, and what looks like a small gpu heat sink with fan. I put it in a tin for some protection but left the top off for max cooling. I like the spot light just where I need it and it is out of the way.
