hygger 18W 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.

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.

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!

Great light for my purpose and it is very bright.

Almost what I want. Got this for sunrise/sunset function and it does brighten in stages in the morning but it gets very bright very quickly. It doesn't do a good job of mimicking a natural sunrise. Disappointing. I took real-time video of what the engineers at Hygger think a sunrise looks like. (These are spider habitats.)

Beautiful light! Works great right out of the box. Plug-in play.

Beware the app doesn't work even if you leave app open with blue tooth and location on. This light decides to come on at 4:00 a.m. at its brightest every morning instead of what the app is set to do. I have to buy a new light because I need the automation or for it to be turned off at some point.

EDIT FEB 14 2023 I 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 REVIEW It 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 COMES This light comes in a cardboard box pretty well packed and protected. There is a plug that comes in as well and a manual. SETTING I 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 NIGHT I 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. REACTIONS This 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 LINE So, 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 RATING FIVE 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.
