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

This light makes me very happy. I love how it gradually dims and brightens to mimic a sunrise or sunset. Very easy to program, just set the time and its good enough for me. Love the moon light at night. very cool product and well made.

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.

I purchased one light for my 55 gallon planted aquarium and LOVED it! It was so much brighter than the other lights I have tried and has worked really well. I really like that you can set the light intensity schedule and I have used that to create a sunrise effect for the morning while I am waking up. It's been great!I liked this light so much that I bought a second one for my other tank which is a 75 gallon planted aquarium. I used the second one in the same way.About two months later, the second light stopped working properly and I was bummed out. I contacted Amazon and they said they could not replace the light because I has surpassed the "30 day return window".So, I reached out to the manufacturer and sent them a video of how the light was behaving (only some of the LED's were functioning). They responded quickly and are shipping me a replacement light!I love this light, but I was a little bummed that the second one stopped working. However, I was very happy that the manufacturer was willing to help me out and send me a replacement light. Giving this 4 stars because although I did experience issues with one of the lights the manufacturer was very helpful in making it right for me as the customer, even though I purchased through Amazon. I have not had any issues with the first light I bought and I have been very happy with it.

This is a good light, but now there is even a better light in the market called the Brite which is bluetooth activated with UV light and easier to customize for your planted aquarium. This light is pretty easy to program, I’m not sure why I see so many reviews complaining that this is a difficult light to program…. Took me like 5 minutes to set up for a Siesta Planted Aquarium for my 29 gallon and 5 gallon planted tank. Plant growth has been crazy with the Siesta Method. Currently I’m using a Siesta Method with this light with the current setting:To set this light for custom mode. You first need to turn off all your other mode first or it is not going to work! Then you simultaneously press the setting and light bulb button at the same time. Remember need to set it to ON then press the setting button again, and you will start with L1 with the flashing number on the right. The number on the right indicates the intensity. Press up and down to control the intensity. Once you are satisfied with the intensity, press the setting button. The left side time flashing is the time your light will be on. The right time flashing is the time your light will be turn off. Press setting to confirm your time and it will switch to L2, repeat your step. Literally L1 - L8 is like a timeslot that you can customize…. How can people not understand that?….L1 - L6 is full spectrum and L7-L8 is night spectrum. Always have 0% on L8 if you dont want algae. If you want algae and have your night mode on the whole night then go ahead.Light 8am - 12pm on. 12 - 4pm off. 4 - 10pm on. This would allow for a 4-4-6 siesta planted aquarium.L1: 8 - 9: 50%L2: 9 - 12: 100%L3: 12-4pm: 0%L4: 4-5pm: 50%L5: 5-9pm: 100%L6: 9pm - 10:30pm: 10%L7: 10:30 - 10:31pm: 0% To turn off the night lightL8: 10:31pm - 7:59am: 0% To turn off for the night and reset back to L1 timeThis siesta light setting is perfect to view your aquarium and let your tank Co2 reset.
