WRGB II LED Light: 3 in 1 RGB leds, APP controllable, 3 colors(Red, Green and Blue) adjustable. Perfect choice for high-tech aquariums, even with the most demanding plants.

You can even set sunrise and sunset with a few clicks in the app which is not only cool but also better for your fish than suddenly turning the light on or off.
