hygger Auto On Off LED Aquarium Light 48-55 Inches Dimmable 7 Colors Full Spectrum Fish Tank Light Fixture for Freshwater Planted Tank Build in Timer Daylight Moonlight & 24/7 Cycle

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.

One of the best budget lights ive used for the money. Could be alittle better on the control settings options but it works good. Can be difficult to set up. Take your time setting it up. Does get pretty warm. But most powerful lights like this do.

Purchased 2 of these lights to replaced a 34" aquarium light hood that had 4, 24", 24 watt T5-HO bulbs. I had 2 units over a covered 29 gallon glass terrarium (34" l X 12" w) between 6 in-12 in from the light for sundew plants that have high light requirements. And yes, the units hang a bit over the edge on the ends due to my error of not measuring first. This resulted in the need to ghetto fix how they are mounted onto the terrarium. The provided mounts put a bit of space between the top of the tank and the lights, this reduces and spreads out the light and keeps the aquarium on the cooler side. That gap in space also causes a reflection of the light from the glass/water underneath, blinding anyone walking past if the aquarium sits low. A 1" reflector or hood attachment along the sides of the unit would solve this and allow more light utilization (Why light up the ceiling???), but manufactures seem to ignore this in most LED aquarium lights due to how they focus light in one direction. The light's metal outside casing is hot and put off quite a bit of heat. Hot to touch but does not burn the skin immediately(~130-160F). The glass cover shields most of that heat, and the plants seemed happy continuously flowering. The light is very bright on 100% brightness but dimmer than what I expected for 60 watts of LED. The light is focused more in a downward direction when 6"-12" away, so full sun plants need to be directly under the light thus the need for 2 units. The timer/dimmer/light color functions are nice which is why I bought the 2 units in the first place. Figured I could dim them if there was too much light, but too little light would require another more expensive purchase. Overall happy with the units themselves at this price range. A major drawback however is that the power supply failed on one of the units after 11 months of use. I knew at this price range something would give eventually but I have never had a power supply fail before. At least its an easy fix if I can find a replacement. Update: increased rating by one star due to the company contacting me after the review and quickly replacing the power supply at no cost. Considering I purchased this 11 months ago, there was no obligation to replace it. Nothing beats good customer service.

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 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.

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.

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.
