NICREW C10 24/7 LED Aquarium Light for Plants 18-24 Inch 13 W Full Spectrum Aquarium Light with Timer, Adjustable Brightness

I really cannot stress enough how much I love this light. I have the 12-18 on a 10 gal, and it did look a little short to me at first but puts out a ton of light, and I would like my fish to have some shadey corners to get out of the bright light so it's really perfect. The brackets are a little short, it would feel more secure with an extra inch of bracket, but then I dunno if it would fit on a 5.5 gal, which It fits nicely on. I cannot definitively tell if this size is aluminum casing, but the 18-24 in model is. Things I love: -It is very low profile. If you position it right, you can sit/lay on the couch and the light blends into the black rim of the tank and you can't even see it, which makes it look like a beautiful glowing slice of the sea! -Timer and daylight cycle runs itself -Pre-programmed daylight cycle, ready to go out-of-the-box -Slow on/off doesn't scare fish, ramps up/down in 15 min intervals -I can set it on fun colors for gatherings -Very bright -The cord is long -It does not seem to put out much heat, although I do not have mine sitting on a hood. -It is very light-weight, so much so it does not support the cooling fan (tried just to see). **It is the nicest light for personalization. You can personalize your daylight cycle 24hrs, 6am-8am-10am-12pm-2pm-4pm-6pm-8pm-10pm-12am. (From 12am-6am it will remain the same, and you could run moonlight all night but it grows a ton of algea and isnt really good for the tank.) I add in a beautiful sunset effect before bed that REALLY makes my betta look stellar. -VERY afforable option for small tanks Things I don't love: -The plug is bulky, has to go at the end of the power strip -It's not waterproof, although my cat has knocked this is once or twice and I immediately got it out and it was okay. -If the power goes out, it restarts at 6am if in daylight cycle (other stationary modes would be resumed as normal) -Bracket feels a little short (although it does remain stable and does NOT dip in the middle due to the bracket being too short) I have now purchased one of these lights for all 3 of my tanks and I've been extremely happy with them so far. FYI, the same remote works for all 3 lights, you just have to point it at the one you want to control, so you dont have to have multiple remotes sitting around. Might be a mild issue if you have 2 tanks really close together tho, I have not tried yet.

I can only speak of the short time I’ve used this light but I have been pleasantly surprised at how good it is. I have lights on other tanks but they are very much manually controlled. These however have the ability to use preset or custom routines to turn on, change color and turn off without any need to be done manually once set. So you can set it and forget it. I enjoy watching as the day passes the 24 hr cycle that is preset I haven’t tried to customize it as yet and am impressed at how close it mimics realtime lighting. So as of the light use I have made of it I am very happy with the purchase.

A little bit big for a 3 gallon cube tank that I have, but I knew that going in - this one was the smallest one they had! The light is fantastic - my Betta loves it! The 24 hour feature is super neat. Have yet to customize it or anything, but even out of the box, it’s basically plug and play! Word travels fast about this one - was recommended by my brother, who has a larger tank than me!

I love this light and my plants do too! The 24/7 feature is really cool and super easy to setup and customise.

The light works well, but it needs to come with more instructions for setup. There are 3rd party setup resources online but it would’ve saved a lot of time to have the product come with a more comprehensive guide.
