I’m really impressed with the hygger Auto On Off LED Aquarium Light! It’s an incredible upgrade for my 12-18" freshwater planted tank. The light is full spectrum with WRGB lamp beads that simulate natural daylight perfectly. The colors are vibrant, and it really makes my water plants look more alive and lush. It’s amazing how the light brings out the true colors of my plants, making them pop in a way that I never expected.The programmable features are awesome, especially the 24/7 lighting cycle. I love that I can set the light to automatically adjust throughout the day, simulating natural light patterns. The night mode is a nice touch too—setting the light to a softer color like red or blue for the evening is perfect for creating a calm atmosphere. The LCD monitor on the controller is super convenient; I can easily see the current time, brightness, and settings at a glance, and it makes programming a breeze.As for build quality, this light is solid! The IP68 waterproof rating gives me confidence that it’s safe from water splashes, and I don’t have to worry about humidity affecting it. The aluminum shell is also great for heat dissipation, and I’ve noticed no overheating even after long hours of use.This light comes with everything you need, including adjustable metal brackets for easy mounting and a handy user manual. It’s been running for weeks without any issues, and I love how energy-efficient it is.If you’re looking for a high-quality, customizable aquarium light that’s easy to install and maintain, this is definitely the one to get. Highly recommended!

Currently using only the 999 model. Have 5 - 36" models, 1 -30" model. Also recently ordered 2 more 30" models and 1 - 48" model due to how well the others have worked. Original 30" and 36" lights have been running daily for just shy of a year with no issues and plants are flourishing. When i ordered the last 3 - 36" lights for my 40 breeders and a 60 gal. one arrived and would not power up, shot a video of concern and notified customer support, a new power pack (plug) was sent out next day. Unfortunately it took longer than it should have imo to receive and delayed the tank getting set up with the others. When setting up i highly advise, depending on what plants your growing and your tank depth of course setting the light at no more than 40% (low light, no Co2) and trying it for a couple weeks. Instead of blasting your tank with full light which will undoubtedly cause an algae outbreak. I currently use them on a 29 gal(30% diy mode), 2 - 40(30% 24/7 mode with 1/2 hr 25% green night light) gal breeders, 60 gal(40% 24/7 mode same as 40 breeders) and on a 135 gal(diy mode) only the 135gal is at 50% with low light plants. (no floating plants for shade in any tank) These lights are strong. All tanks set at 10 hours after being at 8 hours for a month. Growing Jungle Val, Rotala rotundafolia, Bacopa, Ludwigia red, java moss, guppy grass, Anubias.

This light fixture puts out plenty of light for my 5 gallon planted aquarium. I like that it is programmable, fairly easy to setup, and sits nicely on top is the aquarium over the flat, glass cover. The fixture is sturdy and seems well built.I removed 1 star because the controller is not easy to use. Tweaking the settings is a bit of an ordeal. The buttons are difficult to push and must be held in to select a function. This sounds so much easier than it is. It takes several frustrating tries cycling through the options to get to the one to update.The light does not evenly light my aquarium. For my 5 gallon tank, the light doesn't extend across the entire width of the tank leaving the edges darker than the center.Overall, I like this light. It functions reasonably well for a budget light. Once it is set up and adjusted it works well without and additional interaction from me. My plants are growing well and the aquarium looks great.

Muy buena compra, la compre para automatizar mi pecera y cumplio perfecto. Tiene la opción de día, noche y 24hrs. La programación es un poco enredosa al principio pero ya que le entiendes es muy facil. Lo único es que si la luz se va, el reloj se desprograma y hay que iniciar todo de nuevo, pero pues supongo es normal.

La lámpara está de muy buen material, se adapta perfectamente al acuario, la programación hay que buscarle un poquito, lo único que no me gustó es que cuando se va la luz se desprograma el tiempo y ya no apaga en el momento que debe de pagar, encuanto a ilumiinación tiene muy bonitos colores y sirve para acuarios plantados, pero siempre hay que buscar qué tipo de plantas requieren esa cantidad de luz.

This light works perfectly for my 10 gallon. It's so easy to set the timer, and it's always consistent around the clock. One of my favorite features is the gradual fade in and out of the lights; the lights don't abruptly switch on at the exact minute you set them to and actually turn up a little bit at a time. This is great for my betta, since they don't adjust to sudden changes in lighting as well as other species, and can get damaged eyes if dazzled.You can also change the color! I set my full spectrum for a daylight cycle, then do a little 50% B + G action for the first few hours of the night. It switches all on its own and I barely give a thought to the lighting unless I'm shuffling some plants around.I've used this light for months now and haven't had a single issue with it. Even when our power went out during storms, my time settings were saved and I only needed to adjust the clock.Highly recommend this bad boy if you want a full spectrum sunlight type of thing for your plants + don't want to hassle with an obnoxious LED fixture. Definitely a great deal for the price. Just be careful how you scape with plants that prefer more of a dim atmosphere, like them java ferns, because the light is pretty powerful and can scorch them. Other than that, this thing is great 👍 you should get one
