Fish Tank Clip on Light, VARMHUS RGB Clamp Aquarium Light Fish and Plant Aquarium Lighting with Timer Dimmer for Sunrise and Sunset (7W)

This light works great in my 17-gallon tank with about 20" of water--it shines brightly the whole way to the bottom, and stays exactly where I put it. The flexible neck doesn't move, and neither does the mount. It does get slightly warm on the back, so it's probably not as efficient as it could be.I do have some algae problems, but that's my own fault for not limiting light time better.

I've had this light for over a year now and it still works great! It even fell into the water once or twice when I was moving it and no problems! One of the buttons did break but it was from my own fault. My plants are doing great from it's source as well!

Over the passed few years I purchased 13 of these lights, and of those 6 stopped working after around a year of use. Not fixable, but still I'd buy them again being they function well, until they break down. The light output is adequate with my living plants aquariums group and the built in timers stay set to the on and off cycles your have selected. Though if you have even a brief power outage you then will need to reset its timer setting. The light design has a nice look over an open top aquarium and its goose neck is handy to angle them to your preference.

Just what I needed for my 3 gal betta tank!! Light works very well and attaches nicely to the back of the tank. It has a slit in the middle in case your tank has a split filter on the back like mine does. Provides just the right amount of light and has nice spectrum lighting, red and green! Has multiple different brightness settings. I have mine on a smart plug!

I bought my two boys these lights for their Christmas lol and they are amazing! Super easy to clip on and they create a natural light for them

Do not get this, if you move the wire or the lamp a certain way the will flicker and stop working and then if you adjust the wire, it will start working. the way they package it is a no for me it was cramped, when I got it I plugged it in and set it up it wasn’t working till I pulled the wire a little and it turned on

I put these lights in all of my fish tanks I have about 10 of them I absolutely love them they help the plants grow and keep them healthy Love the blue light and the fact that they have three different kinds!

Worked fine for the first months, and the timer function was nicd, but now the LEDs have almost fully died 8 months later and it barely produces any light.
