Review on COVOART Aquarium Underwater Submersible Crystal by Cathy Blount

I really like these lights, with a remote control. I bought one of the 15" that I put under my gravel. I then bought a 7.5" unit to place in the back of the bottom of my 5.5 gallon glass tank with the lights were angled slightly downwards (to keep them from bouncing off the glass) I could only use one set but I love watching my fish swim before I fall asleep at night As he sailed along the front my decorations cast a shadow, and I couldn't see him well. Since the lamps are dimmable, I decided that it's better to have more light than can be dimmed. Against not having as much light as I would like. I'm very happy I said I added a second set and I would definitely recommend them.They are not very expensive and look great.I don't use the bubble option as I don't like having a lot of bubbles constantly circulating in such a small tank .So I can on this aspect of these lamps say nothing. Otherwise I can only recommend the purchase!
