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

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.

Works Great, Super easy and simple to set-up, I don't know what all the complaints are in other reviews about being able to set it up, I was able to set it up without needing to read the instructions, only thing I think that needs to be tweaked is the brightness of the moon light, Moon light should only go to 50% not 100%, but it's a minor thing, for the price and what you get its great

First off, the default color temperature is pretty high up on the kelvin scale (aka, pure white, almost saltwater style, not quite blue). I'm not sure how to change that even though the color temperature is listed as a range. I do not like the default schedule, it does a weird overlap with the "moon light", the moon light runs way too long into the night, and the default brightness on the moon light is way too high. If you change the brightness during the moon light period you kill the schedule and must manually turn the light off to go back into normal mode. Weird. What is also weird is the light does not remember the time when unplugged. It does like a full factory reset if it loses power for any reason. I have not tried the custom schedule mode, for fear that it will be hard to customize in the clunky interface and if I screw up it will not remember any settings on a power off reset. If you are willing to live with all that, and use the default schedule, it's a great LED light! I have the 26W version and it fits/lights perfectly an ADA Cube Garden 45-F. I wish the default sunrise and sunset were way more yellow, they seem to just ramp the intensity of a very neutral white constant color temperature the same as the mid day setting.

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.

Highly recommend this light if you have planted freshwater tanks. Perfect spectrum of color waves to help plants grow and thrive. The build is slim but powerful and the unit does not get too hot like units I have had in the past. Only been running for a few weeks so if I notice anything I’ll be sure to update but I found programming it simple and straightforward with the instructions given in the box. Very nice to have the daylight, full light, and moonlight settings that I can set to how many hours I want my plants to have in a day without needing to turn lights on and off. Highly recommend this product for plant lovers!
