hygger Auto On Off LED Aquarium Light 30-36 Inches Dimmable 7 Colors Full Spectrum Fish Tank Light Fixture for Freshwater Planted Tank Build in Timer Daylight Moonlight & DIY Modes

First professional light i have purchased outside of the light that came with the aquarium. Once installed and configured the light output into the tank was amazing. Even the wife was impressed. lol. The outside casing gets a bit hot to the touch. The color and on and off timer settings, remain after short power outage but are easy to reset up if need be.

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.

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.

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.

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 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.

Firstly, the delivery is great! It came earlier than expected. The product's build is good. The complaints by reviewers about the control panel being sensitive to touch is real. Just have to learn to get to use to it. Overall, it is a good product from my unboxing it and trying out the modes and settings. The standard mode should be adequate. Just ensure the time settings of Day-ON and Day-OFF that work for you.

Been using this light for about 2 months. Very bright and I actually only use it at 50% as I have no plants to grow. In the automated setting you can not dim the light and I found it over powering. I "DIY" mode though you can set the intensities of each stage of the timings. There are 8 total diy setting modes you can program in that let you set on/off times with intensities. 1 through 6 give a nice clear white light, 7 and 8 give you blue. All 8 modes can be run dimmer mode. During power outage it will remember your settings but you will need to re set tge time. A bit of a pain but also eliminates need for a battery backup in the light. As long as I have no issues in future I am extremely happy with it. From my understanding the manufacturer is also very good at making issues right which is some peace if mind as well. I bought the 48 to 55 inch verson and at that price you are actually getting a very good light at a very reasonable price compared to other options. It may be a little more expensive than the real bargain brands but the programming function alone makes it well worth it. I've bought a second one now for another aquarium.

Only problem is that the user manual is too concise to understand the settings. Otherwise this is the best light I ever used in my 20 + years of this hobby.

Sus funciones de simulación del Sol y luna me gustaron mucho, pues no se prende ni se apaga de golpe, si no que va incrementando y reduciendo su intensidad lumínica en una pre programación de fábrica, y solo ajuste a mi hirió preferido y está funcionando hizo lo suyo automáticamente. La recomiendo mucho, yo me he dedicado a fabricar peceras de acrílico y dar mantenimiento, y está lámpara supero mis esoectativas dado su precio, pero hay que considerar que no la recomendaría para corales vivos en peceras marinas, pero si para plantas en acuario de agua dulce. Valió la pena la compra y solo espero que dure lo suficiente 😃👍

Es muy buena, con buena iluminación.
