hygger Aquarium Programmable LED Light, for 18~24in Long Full Spectrum Plant Fish Tank Light with LCD Setting Display, 7 Colors, Sunrise Sunset Moon and DIY Mode, for Novices Advanced Players

First off, the seller/manufacturer is straight up great. Honoring their warranty is integral to a great product. I’ll elaborate in a bit. Second, if you are looking for a bright led light for your aquarium, this is it. And fully customizable with an auto daylight/moonlight setting with digital readout default. Its awesome. A few points: I read reviews that complain about heat. Apparently these folks were born never have experienced incandescent bulbs. These were 120-250 degrees in your ceiling or on your desk. And yes, in our aquarium hoods back in the day. Hot as F. If you complain about the heat of this light, you may want to take up badminton or knitting. Manuf states 120F or below is Aok. Another point, the instructions. If you cant understand them, change your name to Billy Madison and go back to kindergarten. They are pretty clear. Read, follow directions, Push buttons... simple. Failure. I have several of these lights. One failed a few months in. It couldn’t keep the time and would reset constantly. In this case, I contacted the seller and they took care of it. That is the best. I hope these lights last a long time and I will update this review accordingly. So far A+ rating.

I really like this fish tank light so much I bought two and plan on buying another one and even persuaded a friend to buy on and he absolutely love it! One size is for the 10 gallon tank and the tank below in the pics is a 5.5 gallon rimless tank. Keep in mind I had these lights for nearly a year before posting this review to make sure they're good and so far they are. My friend bought one for his 20 long tank and he fricking loves it! The cool features are the timers and how it fades into moonlight when programmed. Buy one you won't regret it! Updated pics since I rearranged and moved the tanks around. The lights are still running great!

Very surprised so far. I pulled an old 10 gallon tank out of storage, cleaned it and decided to build a small betta/plant tank to fit a spot in my house. Bought this because the hood on the old tank was just...old...and I wanted something that was more plant friendly. The plants seem to be doing well after a month. I love how this is pretty much automatic. It slowly comes on in the morning, then cycles down to a lower light color in the evening and has a "assorted" mode which is awesome. FYI, the bright white does heat up the unit, however every other color is cool to the touch, no matter how bright you have it. I would recommend wiping/cleaning the underside of the hood a couple of times a week. What I've noticed so far is "splash" of the water from the filtration will attach to underside and might take more of a "elbow grease type" cleaning if left alone for a couple of months. I don't trust the "water proof" claim. I have noticed a few beads of water inside the unit while cleaning. No, I haven't placed mine in water, it came from the filtration bubbles. Maybe mine wasn't sealed correctly? Overall, very pleased with the item and if I rebuild my later tank, I would look into buying another one for that size.

If you you’re on the edge about this light I can soundly affirm you that this light is worth every cent. It was packaged very well and the light seems to be of great quality. I personally really like how the operating manual and controls are quite simple and easy to use. All you have to do is set your local time and you’re already set up pretty well. And if you feel like you want to do some fine adjustments then that’s just as easy. After two or three days I had mine dialed in right where I wanted it. I read a couple reviews were people say this light get extremely hot but after purchasing it for myself I found they were being extremely over dramatic. A desk lamp gets hot, this light (at full brightness mind you) only gets warm. You could easily hold onto this light with your bare hands. Heat dissipation is not an issue. For the quality, amount of adjustment, ease of setup, brightness, and hands free lighting I highly recommend this light. So far I’ve found no qualms to it.

I love these lights. I run them on multiple tanks. My plants grow out of control in all of them. It is adjustable. You can set the on off times and not worry about it. This light pretty much provides every feature you need. It is also water resisitant. I ha w dropped them in my tanks multiple times with no problems.
