hygger18W Smart Aquarium Light, Bluetooth LED Light with App Control, Full Spectrum Fish Tank Light with 24/7 Lighting Cycle, 5 Modes, Adjustable Timer, for 12"-18" Freshwater Planted Tank

App is a little annoying and finicky, but the light is great. Powerful enough to keep even our red plants happy, adjustable enough to keep algae at bay. Running this on a 14 gallon cube. Accidentally dunked the light in the tank a couple months ago, twice...about a week apart. Dried it carefully and is still working well, thankfully. For the price, I'd highly recommend.

After 3 months light stoppd working. Bad Quality

Great light for my purpose and it is very bright.

I bought this light to upgrade my 40 gallon planted tank. It’s a great upgrade! The light is bright enough to light the tank from front to back. The previous light was too narrow and dim. I like the app. You have to upgrade the firmware on the lamp when you first connect it. I think that is why some may be having an issue with the app. Also I at first downloaded the wrong Tuya app so be aware that there another app. You want the Tuya smart app. All said I think this is a pretty good light. It’s growing my plants great!

Has a good range of lighting from 3000-6000k and fully adjustable with app. But the app is its downfall, the app takes awhile before it comes on to link. If it even links. Crossing fingers that this app doesn’t fail. Timer feature doesn’t WORK!! So maybe I should give 2 stars but I like the adjustability of the light tones

Still trying to get Hygger to respond to email trying to get service under 1 year warranty. After less than 3 months use, the power button shocked my finger and all controls stopped working. The light is permantly on at 10% brightness and must be unplugged to turn it off. Tuya app and manual buttons no longer work to control it. I wish Hygger would respond to my warranty coverage request email. Tried their phone number and it is impossible to get anything but a busy signal. So far, this light by Hygger is something I can not recommend. If I get warranty service, I will update this review.

EDIT FEB 14 2023I have decided to use the app due to the light having to be adjusted brightness wise daily without the app. I am using the sunrise/sunset setting and I really love it. I had an extra phone I can not use with the towers anymore, and it works great for the light app. Just be sure your location is turned on and permissions for devices in the area and Bluetooth are enabled. This was easy, no issues at all in setting up. You can even do two custom settings if you want. If the power is out, it returns to the settings in an hour when returned. I am very excited about this light with the app and will buy another when needed for,other tank.----------------(UPDATE- I have liked this light so much, I got some neons to put in this tank. I will try to get a photo for you of them. They really look beautiful in this light. This brings out their color better than any other light that I own for smaller tanks in the 3-5 gallon range. I like this so much that I am tempted to replace another light with this one. The depth it adds to the tank is beautiful and I am not even using the app!)--------------ORIGINAL REVIEWIt was time for me to move on from an older natural lighting light on my two smaller 5 gallon tanks. I have quite a few fish tanks, and these needed some help.HOW THIS COMESThis light comes in a cardboard box pretty well packed and protected. There is a plug that comes in as well and a manual.SETTINGI do not want to use my phone to set a light, but I wanted to see if this would respond well to not having an app to use it. To be honest, I like it so much, I don't even consider having the app to mess with.I just choose the sun looking button and it rotates through several settings. They are all well balanced and make the tank look amazing.SHUTTING OFF AT NIGHTI have this on a dual timer which is set to another large aquarium next to this and it works beautifully. It shuts off and then turns on the next day on the same setting it went off at.REACTIONSThis tank happens to be my shrimp tank. I had some baby fish in there who were determined to be kamakazes, so it is now empty. They are a special kind of fish purchased by accident that were beautiful but they are known to jump tank always and most fish keepers can not keep them no matter what they do.As soon as I turned this light on, my shrimp all came running out and were very active. They have been active since the light has been set up. The plants are growing well and are very green. The appearance is beautiful.THE BOTTOM LINESo, you might want the app to run this light which is what its feature is, but I prefer using it without the app and a timer to turn it off at night. You can also turn it off manually if you don't want to use a timer.MY RATINGFIVE STARS. I love the appearance of this light. It really is beautiful, brings out all of the colors and the shrimp all have become very active since I have replaced with this light, despite my previous light being a fantastic full spectrum florescent twist.

Cheap light broke after a few days
