I have been planning on making a bunch of 3W blue LED spotlights to highlight some of my super glowy colonies at night. I'm going to join Milad's next LED group buy and pick up some of those RB Crees and make some nice housings. I'm planning on making them mount on the edge of the tank with a small lamp. Maybe talk to Grizz; I know he's a welder but he might be able to machine some nice housings for the LEDs and optics?
