Review: Great light for a 10 gallon tank. - Great tank light that works well. Love that it can change 3 different color lighting and can also dim or make it brighter. The size i purchase was great for a 10 gallon. Any bigger you will need a larger light bar. Great price and looks great. Easy to use with the switch. It could be on a timer which is great.
Review: Great fish tank light - This light works great as a replacement for my betta tank. Since I put this is and keep it on the blue light and white light algae growth has been at a minimum. Great light for the fish tank.

### ⭐⭐⭐⭐⭐ Great fish tank light

This light works great as a replacement for my betta tank. Since I put this is and keep it on the blue light and white light algae growth has been at a minimum. Great light for the fish tank.

### ⭐⭐⭐⭐⭐ Great LED aquarium light
*by M***L on April 27, 2025*

Love this LED light! It has multiple light intensities and 3 colors: white, blue or a mix of white & blue (which I think looks the best). Also 3 different lengths of time it can be set for. It has been working really well. I bought this and the Tetra hidden led stick. The Tetra was just bright white and did not have all the options like this light so I bought another one of these to replace the Tetra light. I have it on top of a clear tank lid and it has not been submerged in the water so can not say if it will holdup under water like it states in description.
