Does this light have the option to clip on to the frame of the tank? Or is only suction cup?

Answer by Chewy • Aug 30, 2022
This light can be clipped to the aquarium frame or attached to the side or bottom of the aquarium using the included suction cups.

Is this the LED light that has a rocker switch that switches between just blue, off, then blue + white LED lights?

Answer by Chewy • Mar 15, 2021
This light features blue and white LEDs that can be used together or only Blue.

Can you use this light with live plants in a freshwater aquarium?

Answer by Chewy • Sep 25, 2019
This light will not provide enough light, on its own, for plants. Plants need both red and blue spectra for photosynthesis. The red spectrum makes plants grow lushly. Blue light will tend to make them grow upward.

Is there an option to only use blue lights for night effect with this product

Answer by Chewy • Oct 23, 2019
This strip light only emits blue and white lights.

NOT impressed

I have a Marineland aquarium but this will not clip onto the frame. My aquarium is older so maybe the width of the frame has changed. I won't even try the suction

I have a Marineland aquarium but this will not clip onto the frame. My aquarium is older so maybe the width of the frame has changed. I won't even try the suction cups after other reviews say they don't last long. Will likely return this. Very disappointed.

Easy to install

These are fantastic and allowed me to put the lights inside my hermit crab habitat, I haven’t had any issues since buying them

Chewy for the win

Fish tank lights can be so expensive. I was super happy when I found this for half the price as in the store. I just wish the light had an automatic timer. I do

Fish tank lights can be so expensive. I was super happy when I found this for half the price as in the store. I just wish the light had an automatic timer. I do however love that it has different settings options.

Bright and versatile

Good illumination; it can be positioned in different ways in the aquarium or on the frame. The on/off switch has a suction cup, and the cord is long. Two drawbacks:

Good illumination; it can be positioned in different ways in the aquarium or on the frame. The on/off switch has a suction cup, and the cord is long. Two drawbacks: I could not find the color temperature of the light, and the transformer plug takes up too much space, blocking another outlet on my power strip.

Dim

I ordered this light for my 36 gallon bow front aquarium. It was so dim, it didn't even light the corners of my aquarium. I returned it.

Ease of installation

Good addition to nano tank lighting. When you dont want to have main diaplay on but just want some small ambient light on tank.

LED Light Strip

I have a 55 Gal aquarium and I bought 2 light strips. They are bright for daytime & at night I switch to blue. Beautiful! I highly recommend!
