Review on Lominie Submersible LED Aquarium Light (30cm): Waterproof Fish Tank Light with Timer - 3 Lighting Modes, Dimmable Crystal Glass Light for Freshwater - IP68 Rated by Stephanie Anderson

Very nice multi-mode LED night lamp. It's easy to install and use. I'm not impressed that it's submerged in water due to the reflection in the tank. Light reflections can confuse fish and cause stress. If you submerged it I would only use it in blue settings and then only as a night light. That being said, it would be a good idea to use grow tanks if you are growing live aquatic plants and need extra lighting. Otherwise, the light works better over a glass cover or hanging over an aquarium. Otherwise there are no complaints. This is a great multipurpose flashlight for people who love fish.
