hygger Auto On Off 30-36 Inch LED Aquarium Light Extendable Dimable 7 Colors Full Spectrum Light Fixture for Freshwater Planted Tank Build in Timer Sunrise Sunset

So after using this for a while, it has been a real solid light, works well, super bright, easy to program the clock and the timers after you look at the instruction video. I love that it is adjustable in 10% increments on all of the different light settings. Only thing I noticed...it forgets everything if the power goes out and you have to program everything again. My other light has the ability to save everything when the power goes down. Other than that this is a really great light, I would buy this again if I get a second tank.

Great light. I needed alight for a small cube tank and I wanted one that had a timer. Not only is the light perfect for my nano shrimp tank but I love that the timer is built in to it. Makes the tank cleaner without the need for an extra gadget for timing the tank. The size is perfect and it sits nice and clean looking on my tank. Very happy. If I were to point out one picky aspect- I do wish the timer on the top had a dimming effect so it does not seem to always be lit, but this is very miner.

this is a great light. pure white and full spectrum. mine has lasted almost a year until the white spectrum started flashing. i really like the light causes it’s very simple and great for my anubis’s and other redding plants. i have mine hanging and it’s fine. i’ve had mine on multiple tanks up to a 55 and never a problem with growth. great light no complaints here even the morning and night feature is nice.

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 light L8: 10:31pm - 7:59am: 0% To turn off for the night and reset back to L1 time This siesta light setting is perfect to view your aquarium and let your tank Co2 reset. This also reduce algae. This siesta method also work if you have a Co2 tank, you can also use this setting for your solenoid Co2 7-11am on 3-9:00pm on

Updated review: The seller reached out and offered a replacement which I received promptly. I have been using the replacement now for a week or two and it works beautifully. Turns on and off when it should and even has "off" as one of the options as you click through the colors, etc which the last one didnt have. Every time it messed up and did its own thing I would have to unplug it and completely start over. Because of the great customer service and receiving a product that works as stated I have upped my rating to 5 stars. Original review...it started just doing whatever it wanted. I had it set to turn on slowly over 15 minutes at 7am and to do the same but shutting off the light slowly over 15 minutes at 7pm. It worked great for a short time and then started doing the blue moonlight at 7pm and now the light shuts completely off (no dimming over 15 minutes) at 6:30pm and then turns the blue "moonlight" on at 7pm all of which has also never been set and then off 11:30pm so its literally just doing what it wants when it wants and its been changing daily. I haven't ever turned it off by unplugging or lost power so its just wonky and not working as it should. For the price it definitely has not been worth it for me.

This light is beautiful and very bright right out of the box ✨. The color rendering looks great, fits snug on my 40 gallon tank and it definitely makes the tank pop. That said, I ran into some serious concerns. The 30–36” model is advertised as 48W, but when I tested it at the wall I was only seeing about 35W total draw. When I powered the light directly using a bench power supply, the fixture itself maxed out around 33W. That explains why the included power supply seems underpowered - but it also means the light is not actually operating anywhere near the advertised 48W. That feels very misleading. On top of that, the included power supply and cords are noticeably thin. Given the current draw, that raises concerns about long-term durability and safety. Thin wiring under sustained load can lead to overheating, premature failure, or worse fire🔥. It just doesn’t inspire confidence. Functionality wise, the standard sunrise/sunset mode is partly customizable. You can adjust the moonlight brightness and color, which is nice. However, you cannot adjust daytime brightness in standard mode - it runs at 100% unless you switch into full DIY programming. DIY mode is powerful, but as many others have mentioned, it can be tricky to program. If you carefully follow the instructions (and their YouTube video), it’s manageable - but it’s not intuitive. I’ve already noticed visible plant growth after installing this light. The spectrum seems to support healthy growth, which is great. However, being unable to adjust daytime brightness in standard mode can directly impact plant health over time - too much light can stress certain plants and, more importantly, can fuel unwanted algae growth. Another small but annoying issue: the display screen is always backlit. There’s no option to turn it off. Interestingly, the Amazon product photos show the screen with the backlight off “for display purposes,” which feels misleading as well. Overall, the light is attractive, bright, and functional 👍. But between the inflated 48W claim (actual draw ~33W), the undersized power supply, thin cords, limited daytime brightness control in standard mode, and always-on display, I can’t justify more than 1 out of 5 stars.

The light is really good for the price it is. The extended rods definitely hold its weight. And the size is real good doesn't take up to much of the top of the tank. The light reaches really good to the bottom of the tank just make sure you adjust the light setting so its not to bright for the tank you have so you dont have an algea problem other then that no complaints ive always used these lights

I am middle of the road on this light. I do like the brightness adjustment and integrated timer. I don't like the touch sensitive button controls. I don't like the length adjustable arms do not lock into place.
