ONF Flat Nano Full Spectrum LED Aquarium Light, Dimmable 7000K / 1300lm, for <10 Gallons Rimless Fish Tanks, Freshwater Aquatic Plant Growth, Terrarium Spotlight, Potted Plant IP54 Waterproof (Silver)

This light is certainly a bit pricey. However, after 5 years, I can confirm it's well worth the cost.The color of the light is much better than cheaper alternatives. It is similar to real sunlight, which makes colors really pop. I've attached some photos to help illustrate this.Also, they have been extremely reliable. I purchased 12 of these back in 2019, for a variety of nano-tanks and plants. They have been running 5-8 hours per day, every single day for the past 5 years, typically on brightness level 2 or 3 (out of 4). So far, not a single lamp has failed.

I’ve owned aquariums for a long time now, and this light by far is my favorite. The light looks so modern and sleek, and was so easy to install. Just make sure you have a rimless tank. This picture is of a 5 gallon tank, and the light is set to 50%. I love how you have 4 settings. 25%,50%,75%,100%. This light makes my plants and fish pop so much. I have not used the Bluetooth yet, because i just plugged it into my timer. I hope this light grows my plants well, which I’m confident it will. This LED is worth every penny and i promise you’ll love it!

Great light, my favorite for nano tanks. Grows anubias and Bucephalandra well. Only downside is that it died after 3.5 yrs when I think it should last a lot longer. The bluetooth app connects to the light, but it seems the LEDs are out because it wont light up. Cosidering wheter or not to replace with the same light. Hoping the other two I have last a lot longer.

This light is wonderful... by far one of the best lights I own .. grows plants well and has a nice clean white light to it ... its a pretty powerful little light but offers a great range on the dimming functions..if you are looking for a quality light I would in deed recommend this one

Firstly the description says 20” but nothing about this light is 20”. The light bar itself is 11.5”..my fault I should have read the specs. The tank attachment relies on metal screws that don’t even have protectors so it can scratch your tank. The app is awful and the colors are not adjustable. It looks nice, has a nice light, and was beautifully packaged, but I’d just go with the Fluval 3.0 which is way better, and you get MUCH more for the money. This item is way over priced.

I absolutely love the ONF Flat Light! My plants were struggling before, but after switching to this light, they truly came back to life—healthy, vibrant, and growing beautifully. The design is sleek and modern, and the quality of light it provides makes a noticeable difference. It’s definitely worth the investment if you care about your plants’ health and want something that looks great too!

I purchased this light to use on my 6 gallon betta tank. Compared to my Twinstar 450S on the tank next to it, it's significantly dimmer and cooler. It's probably plenty of light for the 6 gallon tank but I wouldn't use it on anything larger than 10 gallons. I don't like the color rendition nearly as much as with the Twinstar, which was comparable in price.The ONS does give you app control whereas the Twinstar does not, and you must purchase a dimmer separately for the Twinstar. Point ONS.I'm not very impressed with the build quality. It's plasticky and there is a lot of play in the mounting bracket. This means you'll have to skew the bracket by 5-10 degrees in order for the light to be parallel to the water surface.edited 11/28/22 - still not terribly impressed with this light. The app is beyond useless. Once you set it up, there doesn't seem to be any way to edit time of day the light increases or decreases intensity. The help option in the app takes you to an ONF webpage that doesn't exist. In hindsight, I wouldn't have purchased this light. Dropping to one star because of how awful the app is.

The media could not be loaded. Probably the best lights I’ve ever purchased. The sleek design and swivel head makes it easy to attend to plants and aquarium maintenance. It doesn’t get in the way unlike other lights that nest over the aquarium on two ends which makes it hard to do anything in the aquarium without having to put it down or it falling in. The height of the light can be adjusted up and down. There’s no wonky screws sticking out because it’s been designed to be as sleek and clean as possible.The app works flawlessly so you can adjust the times and brightness to your aquariums residents needs. It doesn’t get as hot as other lights so this won’t burn you if you need to move it around.
