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!

Worked well for small 10 gallon tank. Not really bright so I would probably upgrade if used on larger tank. Color change was a nice feature, along with timer. Was OK for the price.

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.

Final update. It quit working. I am done. I just bought a different brand here on Amazon. I hope it lasts more than a month. I cannot reccomend this light. Sorry. 3rd update: I am happy again. The seller sent me a new connector. It worked. Turns out the original connector was faulty. All good now!! Many thanks to the seller for fixing this..... *2nd update. Working with sellers to fix the connector. The two round pieces that plug into each other. If they help me I will replace the stars. UPDATE! Took off 4 stars. After about a month, it stopped working. I need to get this replaced. What a pain!!! Not happy. Well with 7 colors and 4 modes what's not to like. I have this on a 29 gallon tank. The light is only about 16 inches. Then the bars slide out. It is plenty of light. Has a very nice built in timer. Now if it lasts through the warranty period of one year I will be happy. Seems to be well made. Well worth it I think! Highly recommended!!
