Review on 7.5-Inch LED Aquarium Light for Crystal Clear Underwater Illumination - Submersible Fish Tank Lighting in White by Monica Bailey

It's strong enough for my 5.5 gallons of tannins and I probably wouldn't use it alone in anything larger than a 15. Suction cups have come off the sides of the tank twice since I bought it but I think it's due to the cord being pressed against the edge of the tank. This seems to have been resolved as I used a clip to bend the leash and hold it in a more comfortable position. My only real complaint is that I wish the cord was a foot longer. (no measurement, is it 5ft? Long enough as long as I don't want to put a loop in it in case water runs down the line). Other than that, I'm happy with this purchase.
