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 18"-24" Freshwater Planted Tank

Very happy with this light. Setting the auto function takes a bit to understand but worth it! Very convenient when I’m not home. Puts out a fair amount of heat, but have it on my 75 gallon tank so not much of an issue. Love that it has adjustable brightness. I need a stand to allow for adjustable height though, just my preference as I have plants in the top of the aquarium that would benefit from the full spectrum lighting as well.

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 love this light. I would've given it 5 stars if I could choose my morning time light color but it defaults to white light. I love that I could choose any color for the evening time on the settings. Amazing price. Easy to use

This is the second of these that I have ordered, and both have been great so far. They are super bright and really brings out the colors of the fish in the tank, and works great for the plants I have. My only gripe with the product itself is that the timer is a little confusing to use but once it is set you are fun, unless the power goes out. On the second light I ordered I ended up with a used light instead of the new one that I ordered but amazon was quick to help with this, but just be sure to check your light and packaging when you get it to make sure you are getting a new one.

Started to get back into my old aquarium with my kiddos and have been doing a lot of research for various items that I need to buy. I needed a new light fixture and in my typical Amazon shopping technique, I'd always filter products that are shipped by and sold by Amazon, to alleviate typical angst with low quality products that usually never meet my expectations. Between various youtube reviews and consulting fakespot, I arrived on hygger. Figuring it had free returns, I didn't have anything to lose if I wasn't initially satisfied. I opted for this particular one as it provided more granular control over the 24 hour light cycle (some would consider that a negative as it adds complexity, but it really wasn't that bad to set up at all). The brightness and array of colors fit my need for my 10 gal tank. I appreciate the thin design to avoid as much clunky objects that detract from the aquarium experience. I personally like having the controls on the wire instead of on top of the led light itself, like other hygger models have - my tank sits higher than normal and would constantly require a step stool to use. For the money spent and the value received, at this early point (only had it for a few days), I consider this an overwhelming win. Granted, time will tell how durable it is - I'll try to make the effort to report back if I encounter any issues in the short run. My only complaint, albeit a very minor one, I don't particularly like how the led light on the wire control never turns off. I would have thought a simple 10-15 second timeout when there are no key presses could have easily been incorporated.

I love how bright this light can get for a planted tank. If you run the light at full brightness make sure the transformer has some room to get air. The light itself does not get above 95 degrees ever. I have never felt it get warm. The transformer that plugs into the wall does get warmer than I feel is ideal so I just turned the lights maximum brightness level down to 80%. This helped a lot and I believe it will add longevity to the product. I own 2 different sizes of these lights with a total of 5 different lights all together of this same model. Programing was difficult to understand at first but after looking it up online it was much easier to understand. This light is incredibly customizable. If you loose power it does NOT lose the programing it just loses the time. So you just have to redo the time that the light knows that it is at and your set again. I will buy more of these as my tank inventory continues to expand with our channel "K.I.S.S. Fish" the value is very good.

This is my favorite aquarium light. I have bought three so far and what I really like about it is the programming I have had other lights that you know you can kind of program to 12 hour length of time, but then it becomes kind of randomized as the 12 hours kind of overlap anyway hard to explain. This one you said it to what time you want to turn on what strength you want the light to be what time you want to turn off what time you want the moonlighting to turn on how strong you want that to be and it’s slowly turns on slowly turns off And then you never have to touch it again. It’s awesome. I like that. It’s full spectrum to help my plants. It’s very high-quality pretty easy to understand the first time I tried to program my light. I kind of stumbled through it for a little bit, but I’m on my third go now and it’s good. One thing that’s nice is if you unplug the power source and then plug it back in it does not erase what you programmed

Short part first. The light is nice and bright, good LED density for the cost. Nice variety of programable colors. Has a built in clock you can program around. Overall I'm very pleased with this light for the cost and have purchased several. Cons: This lamp has one of the same issues all of these white label and generic designs do... The cheap collapsible legs. They fall out, they don't fit tightly, and often it can droop a big if close to maximum fit. Programming the "custom" settings for lighting is the only way to get the best features out of this light. The way you program it is quite confusing and convoluted. This is the ONLY smart lamp I have that I need to keep the instructions for. There is no way to know how to navigate the features without it. You even need the specific instructions for setting lighting color codes. Power plug... All of these lights are the same, they have a cord hanging down that has a plug in for the power adapter. I'm not sure why this design seems to be the standard, but the connection point is just far enough from the light that it always seems to hang at some weird inaccessible angle. if you try to correct this, you normally have to just zip tie the wires high up and waste a lot of the length.
