Review on NICREW Submersible RGB Aquarium LED Light Stick - Underwater Fish Tank Multicolor LED Lights with Remote Control - 7 Inches, 2.5W by Greg Case

This is the coolest light. I'm very happy with how good it is for the price. I like the different colors and the fact that you can adjust the brightness. You can set it to a solid color or cycle through all colors. The remote control is a fun feature. You have to point the remote at a specific spot on the cable (the little junction box with the receiver, not the light) for it to work. Even if you lose the remote control, you can still control the light with the button on the cord. You can rotate the light bar on the suction cups to light it up the way you want. Out, straight down etc. Hopefully it will last a long time but for the price I won't go crazy having to replace it every year. . It's really awesome
