  • Great light! Variable brightness and color, simulated daytime sycle is fantastic!
Color: For plants Size: 12" - 18"
We bought a couple basic 5 gal aquariums for our 2 kids to have Betta fish. The original light was just blue, and attached to the lid. We purchased two of these lights as an upgrade, one for each tank. I love that these are separate from the lid. It's convenient for feeding, cleaning, and various other maintenance needs. The lights offer quite a few colors and adjustable intensities. My favorite is the 24 hour cycle. You can easily set the time on the light, and it will go through a 24 hour cycle of light from sunrise to night time! The fish seem to love it. I also love that these are waterproof. I saw some replacement aquarium lights that said avoid splashing. Seriously? In an aquarium? The lights include bars that allow them to be adjusted for various tank sizes. Awesome for that "custom fit". I absolutely love these lights for their variability and multiple functions. I highly recommend them. ... show more

  • Like it but not much surprise
Color: For plants Size: 18" - 24"
I bought this light for waterproof and price, so far so good. My 20gal is too long for it(30in length), but it is bright and nice. I really hope it could be waterproof. The color of light is awesome!

  • Works like a dream and makes the tank look awsome throughout the day.
Color: For plants Size: 48" - 54"
I have a 48" tank. I used to use two 24" lights that was plugged into two smart switches. I had Alexa on a timer to go on at 8 and off at 8. THe problem with this is the lights wernt gradual increase in brightness then a gradual decrease in brightness. Im sure I was blinding the poor fish every day in the morning. This light, however not a smart light, does have the 24hr timer. You set the current time and it will start to gradually get brighter as the day starts, then will gradually decrease in brightness in the late afternoon. It then will turn off fully at 10pm If you dont like that, you can also set whatever color you want on the RGB Spectrum The device does say waterproof, however, I dont believe it fully is. as I was filling up my tank, some water must have gotten into the assembly and it started flickering. It then turned off and the controller would just light up all its LEDs but nothing on the Light itself. The company did promptly send me a replacement and I was able to send mine back. So moral of the story is, keep it out of water! ... show more

  • Not recommended for a deep tank
Color: For plants Size: 48" - 54"
The light just cannot cut through my 55 gallon tank and support my plants. I would not recommend this for a deep tank at all. Now I have to buy a Different light.

  • Great lighting
Color: For plants Size: 18" - 24"
I have a 150 gallon tank so I used two 22 inch lights. The white light is exactly what I was looking for. It really lit up the whole tank and made it look clean and clear. The other colors are also a great touch, they also were able to light up my whole tank. I’ve only had them for a few days so no issues yet. ... show more
