Theatrus build a controllable aquarium moonlight strip. Royal-blue Osram high power surface mount LEDs provide the lighting, and an ATmega88 the control. RS485 port is used for control. All of the design files should be available shortly.
Its quite potent (visible with the main 6x80W T5s running). Its easy to mount (a handful of command strips have held two up next to T5s for over a year). Its fully dimmable and controllable.
