I bought this to replace my existing faulty LED lights in a 20 gallon tank. The board works very well. The suction cups work very well and are very stable. The color options are pretty cool. But now I use it as an extra light during the "quiet time" in the aquarium. Not bright enough to stand alone. I decided to buy a new cover with LEDs instead of my own. There are some things I will buy in store and not online. This is one of them.
