Review on Top-rated Bestgle Blue LED Submersible Aquarium Spotlights for Fish Tank, Fountain, and Pond - IP68 Waterproof Decorative Light Bulbs with 180° Rotation by Aaron Gonzalez

I was looking for a small light for a 1 gallon beta aquarium. This size was good for the inside of the tank and the light it gave off was nice, but it has a rather large plug that looks pretty ugly. Also, after a week of use, some water got into the case, which made me nervous. I didn't know if it was intentional or if it was a problem. Unknowingly, I took it out of the aquarium because I don't want to go home to an electrocuted fish! I think I could attach it to the outside of the tank and shine the connection through the glass.
