Fluval Prism LED
This little spot light is awesome. Great for target lighting a special plant, or cave etc. It is fully submerible and attaches to glass with a suction cup. Has lots of options for what colors, and lighting mode etc. I wish it had better reception of the remote control, that is a bit tricky. But the reality is the way I use them is it's on a timer and used to spot highlight an area in my tank.
