hygger Auto On Off LED Aquarium Light 12-17 Inches Dimmable 7 Colors Full Spectrum Fish Tank Light Fixture for Freshwater Planted Tank Build in Timer Sunrise Sunset

Excellent Aquarium lights! I use these for my vivariums & they work spectacularly. I did a lot of research before buying these lights & the hygger brand was highly recommended & I can see why. They have many customization options, & my favorite is the DIY cycle so you can set brightness/color/time for the entire day. The only gripe I have (which is a common gripe I read online) is that the instructions are confusing & it can be hard to set up until you figure out what to do. But once I knew how to operate the lights they have been great & my plants are thriving. I definitely recommend these lights for an aquarium/vivarium setup.

This Hygger LED aquarium light is perfect for smaller tanks. The colors are bright and vibrant, and the dimmable settings make it easy to get just the right look. I love the auto on/off feature—it keeps the lighting schedule consistent without any effort. The build quality feels solid, and the adjustable brackets fit my tank perfectly. A great value for a full-spectrum light that makes both fish and plants look fantastic!

Programming it can be difficult. The read out is-small but that can be ok with glasses. However, when I press the buttons it doesn't always respond. Then sometimes it goes to another aspect it shouldn't. I went online and read and re-read directions. Maybe my light is-wonky. I don't know. I just put it on the-24hr auto and leave it be....and pray there's no power outage..... ;)

These are excellent lights. My plants started growing so much better when I put these on my tanks. They don't cost a ton but give off tons of tank light....go for it & try one out

I didn't want to leave a review for this light until I had time to really test it out, and after nearly a year, I'm happy to report its performing very well. I stuck it on this 5.5 gallon shrimp and added some java moss/ferns, 3 different cryptocorynes, and some ludwigia. They've all done extremely well, grown in big and beautiful and continue to thrive. The light itself is bright and the timer feature is appreciated. Yes, it does reset if the power goes out/it gets unplugged, but once you know how to set it up it takes less than a minute to reprogram and is well worth the convenience.

The quality of the light is great, but the product description led me to believe that the light was much longer than it is in reality. It is too small even for a 10 gallon tank! I'm going to keep it for a different tank I'm building down the road, but I had to order another light.

This light is really bright and the plants in the tank love it. It also has the perfect form factor to clip into our aquarium lid. Unfortunately the design of the light makes it utterly useless. You can't control it with a simple switch or smart outlet. It has a built-in programmable timer. The timer completely resets on power loss. The buttons are inaccessible when clipped into the aquarium lid. Condensation pushes the "buttons". If you un-plug it and plug it back in sometimes it's "on" and sometimes it's "off". Usually off. Unless you're going to leave the top of your tank open and drape this across the top, you can't use this light.

Bought this 12-17 inch light because of the simplicity of Standard Mode. Plug it in, set the time and thats it. However, after 2 to 4 days of working well, the light shuts off. Have to reset the light, then it works for another couple of days and shuts off again. Contacted Hygger with the problem and they wanted a photo of the problem in addition to my description of the failure. Sent a photo of the panel with the displayed time and the light off because of the problem. Then they suggested trying the DIY mode which defeats the reason I bought this unit with the Standard mode. I would not recommend a Hygger aquarium light. Update as of 6/29/23: Seller replaced light. So far so good. Update as of 7/7/2023: Replaced light works well.
