ONF Flat Nano Dimmable LED Aquarium Lighting for Planted Tanks

MR.BLOBBY: 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

D. Garza: There's a lot to love about this light, but a few critical flaws make it frustrating to work with. I love the color temperature, it's spot on for fish and plants. The low profile flat design is simple and elegant. Almost looks like it hovers over the tank. The dimmer is a nice bonus, but not totally necessary. I also appreciate that there's no app, no frills, no fuss. Just a light.

Setting the light up on the tank is awkward however. It's hard to balance the mount and you need a screwdriver to fasten TWO screws every time you want to adjust it. It's horrible. You'll have to do a balancing act with the wires, screws and wobbly unbalanced ballast like a drunken elephant on roller skates just to scoot the dang thing over a centimeter.

The absolute deal breaker however is the fact that the light's mount wicks water out of my tank like Niagara falls. Do not purchase this device if the water table on your tank meets the mounting bracket, else prepare for the deluge. Check out some of the review photos...most have low water levels and that's why they are happy.

You've probably noticed that it's also pricey. Is it worth it? Maybe. When the stars...

Jack Wong: I love this modern LED light. The light remembers what setting you set it too so it comes back on at the same power level (25, 50, 75, or 100%) when used with a timer. Also the design is really clean and matches my tank and other gear perfectly. I'm currently using this on a ADA 45F tank.

Note: this light is only compatible with rimless tanks! The clamp/mounting bracket doesn't fit with regular tanks.

I ordered a second one and this one works! With no loose parts in the plug this time. It’s a beautiful light with excellent quality lighting. The button is a little confusing. When I hold it down to turn it off, it gets brighter before turning off. Overall, stunning light. I care about design a lot and this one brings me joy.

This light is broken and does not work :/ The plug has something loose inside it which could be why. Looks nice but I needed a working light. I contacted the seller and am waiting to hear back about a replacement plug. Otherwise I’ll have to return it.

daniel ddaniel d: My first impression of the ONF Flat Nano is that it is a very premium and aesthetically pleasing aquascaping fixture (ADA level). Unboxing the packaging is comparable to opening an Apple product. It has a dense metal construction and has a nice weight to it. It is extremely bright and has great PAR outputs when tested with a seneye PAR meter. This light is designed for nano rimless aquariums. The mount will NOT fit in a standard 2.5 gallon or 5 gallon with a black trim. The high price this fixture sells for is justified if you want a luxurious aquascape look. The fixture itself is a piece of art and comes in silver and rose gold colors. This light has strong PAR outputs (At 9" is 145). More PAR data can be found at my website. Just google search "aquarium par data"
