hygger Auto On Off LED Aquarium Light, Full Spectrum Fish Tank Light with LCD Monitor, 24/7 Lighting Cycle, 7 Colors, Adjustable Timer, IP68 Waterproof, 3 Modes for 30"-36" Freshwater Planted Tank

This is an amazing light. Programing it is kind of a pain, but not enough to remove a star. It has all the colors and my plants are looking amazing. It's a great value for your money. I only wish that the risers were included. Having the light sit so low doesn't allow for great light exposure when you have a large tank.

Started a new aquarium earlier this year. Didnt want to buy a kit that comes with everything. I wanted specilal filters and lights. I did a lot of online research before deciding on this light. It is a very high quality full spectrum led light. I has a ton of features , including a DIY timer and light intensity settings. Therre is no way that I can say in this review , just what all can be done with this light automatically. I have a moderately planted 29 gallon tank. I am more interested in the plants than the fish. But I do like and have both. I set the timer to come on at 8am. It comes on in a sunrise ,ode for one hour and yhen goes into the full light for the next 8 hours , then rampms down to a sunset mode for the next hour , then completely off for the night. Tis light is completely adjustable as far as the light in tensity and the on off time you desire. You can set the intensity on the white , blue , green and reds as you so please. This light was very well thought out when it was designed. I absolutely love it and HIGHLY recommend it.

When it comes to budget friendly alternatives to the “bigger better” brands, I’m a fan of Hygger. For the money, their products are hard to complain about and this light does not fall short of that. The light itself is awesome. It would undoubtedly be 5 stars from me however, programming it to run a schedule is an absolute dumpster fire of a process. No doubt it works, but it takes some playing around with to get it right. Unless you have the mind and the patience for stuff like that I would strongly suggest going with the HG-018. That being said, hope this helps you like it did me. Press M to cycle through daylight, moonlight and manual light settings labeled 51, 52 and 53 and hold M to enter and up/down arrows to adjust the field you're in. You must turn off both the daylight and moonlight settings under 51 and 52 before the manual programming will run. I could not get the factory reset to work holding the down and color buttons but unplugging it will do the same thing. Press M until 53 appears, hold M to enter the programming. There are 8 slots labeled L1-L8. L8 is permanently set to 0% light for night so fill in the other 7 accordingly. M again will cycle through the start and end times and light color/percentage fields. The start time of the next slot will automatically begin from the end time of the previous slot. Using 24hr time may also be easier. When you reach the light field, you can cycle through all 4 colors with the color button, each color can be adjusted between 0 to 100%. Any number of them can be used alone or together, each being set to any percentage individually. Once you reach the end of L8 it automatically saves and exits the programming. Changing anything requires cycling through the entire procedure but you don't have to re enter everything unless it's had the power removed from it. The lights do not immediately turn all the way on suddenly, they will slowly turn on over a few minutes

Do not look anywhere else. If you are going for a "low-tech" tank, THIS is your light. The only reason you would need something brighter is if you are injecting CO2. The light makes my tank pop SO much better. The controls aren't SUPER intuitive, but the directions are enough to get you to the point of figuring it out. Once you do, the customization options are massive.

Great light love the timer setting it simulates sunrise mid day and sunset

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!

Yes, programing can be tedious. Take your time, be patient with the directions and yourself. If you choose mode 53 (DIY), make sure you turn OFF the other two modes. Being able to ramp up and down the intensity (& color) on a schedule is a feature i've wanted for years. I went for a gentle warm white fade up in the morning, then a couple of hours a bright white mid-day, and a progressively more red shift as the fadeout works into the evening, finishing the cycle with a couple of hours of 10% blue-only before going off completely just before midnight. The quantity & quality of light is truly amazing for fresh water. I haven't had a salt tank in years, I can't really speak to its blue output being appropriate to make a salt tank have that gorgeous blue/uv pop!. This IS a wonderfully flexible fixture for the cost. We shall see how well its holds up longterm. The only two 'Cons' I see so far, the shortest of hiccup in the power will clear the clock setting, it holds the programing, but not the time. Makes me ponder putting a very small computer style UPs on the aquarium. Lastly, the brackets holding the light over the tank make me a tiny bit uneasy, if younger children interact with tank, or if you live in an earthquake prone area, in just my opinion, its possible the fixture could end up falling into the tank. Perhaps its not meant to be used on an open-top tank, that said, I may put a piece of plate glass under the light. Both of these topics are mentioned in the instructions. In short, for the money, its such an amazing light! ..even for uses beyond an aquarium. I am very pleased with the purchase.

I bought this 6 months ago, but only got it programmed today. I tried twice before to follow the manual. Word for word, I analyzed the directions. The first time I had too many distractions. Second time I got very frustrated and had to stop before I started screaming. For months, I had a very undesirable program and I reverted to the bulb switch, but then it started turning itself back on during the night. Then I unplugged and replugged the damn thing everyday. Here’s what I did and suggest. 1. I found 1 brief YouTube Video by Bob Moss which helped some. (IT would be nice if Hygger made a video-hint-hint). 2. Secondly, I realized the terms 51 for “Day” and 52 for “Night” are misleading. 51 will program 24 hours and allow for one level of white light that you set between 10%-100%. 52 Mode is for the blue lights only, sort of like a night light. THe program for this appears in the 2nd rectangle. Mode 53 is the Ultimate Programming that I’m not ready to tackle yet. The manual should, but doesn’t tell you what these Modes are for; only how to set them. 3. Under how to set the 51 Day mode, Once you press the M CONTINUE TO HOLD IT DOWN TIL IT READS 51 AND THE DAY-L-ON OFF FLASHES. 4. I internet searched for a few questions that were not found in the manual, such as: 1. what happens to programming if you have a power failure 2. How do you get it back on program after using the bulb button? Since I just got mine programmed, I can’t say how well it will work. I expect good results based on reviews, If it doesn’t, I’ll write again. I hope this will help with your programming.

7 month mai light puri tarah kharab ho gai keval adopter mai light on hoti hai time nahi aata blank display aati hai

Item arrived in good condition.

Excelente para quien busca una lámpara automática, tarde en configurarla pero vi en YouTube un tutorial y quedó genial

Pedí dos lámparas una llegó en perfectas condiciones y la otra no, pero ya comencé con la devolución, más sin embargo es lo que estaba buscando

Luminária tem um espectro amplo de cores que destaca e desenvolve bem as plantas. Considero a quantidade de luz (lumens) muito adequada, sendo que é possível reduzir através de configuração. A configuração pode ser um pouco difícil para algumas pessoas no início, mas tem o manual orientando, depois que se aprende fica simples. Resta saber apenas quanto a durabilidade, e isso não posso afirmar ainda, preciso que dure alguns anos para compensar o investimento. Se isso ocorrer, essa marca será a minha marca de luminária para aquários.
