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

I took a chance on this light and I 'm glad I did! I have since bought a second one for another tank. I have this on a 10gallon tank, and I feel like it's the perfect size. I love the simplistic timer. Color coded to reflect which length of time to be on and turns on each time at the exact time you've pressed the button. No need to input the local time, just turn it on at the time you need it and choose the length of time. I have it set on the 10hr. It's growing my plants great and there is 10 different brightness levels with several different modes, white only, full color, blue only, etc. Great light. Plus with it being a clip on, it also gives ample light to grow pothos in the back as well!

I have been using it for a while and I have to say that the design of this timer/dimmer is really easy to use. It has 9 levels of brightness, and I can choose the brightness I want. In addition, it can also be timed. I set a 6-hour timed mode. At the same time on another day, the light will automatically turn on and off. It's so convenient!

I purchased two of these for my 125 gallon acrylic tank. They fit on the side of my tank, which is hard to find. Most clip on lights are too small. I also like how these lights are adjustable. I can move the light around and position it where I need it. These lights are also not very hot, which is good with acrylic. Heat can potentially warp. They are bright enough for a large tank, but you need two in order to illuminate a 6 ft tank. I like the timer feature, but mine do not work consistently. I will set it to shut off in 12 hours, and it will work for several days and then stop. It still works, but it would be nice if it was consistent. The lights each have three settings for white, bright light, blue lights with more color? Really good for the price.

Installation was very easy and straight forward, the goose neck is flexible and sturdy, and the light was brighter than I expected which is a plus. It’s a sleek design that looks good on my aquarium. 10/10 would buy again

Love this light. Only four buttons to learn. White, blue, hours and power. Hit the white or blue button to adjust the intensity up or down...hit the hour button for how many hours you want the light on (4, 8 or 12) and it will turn itself off. And the power button is self explanatory. Simple, yet functional. Two thumbs up!

This small but flexible Fish tank light has various settings and clips easily to the top of the tank. I love leaving on the black light with my glow fish swimming around.

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.

It’s a great light, nice & bright.. but I’ve had some difficulties. They put a film on the light that is difficult to remove. I received one light that stays on blue & doesn’t change to the white light. Other than that: it’s a good light at a decent price.
