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 18"-24" Freshwater Planted Tank

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.

The media could not be loaded. 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.

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.

I’ve been using this light for a few months now. It works great for my shrimp tank and has helped my live plants. It was a little low for my water lettuce, so I printed two different risers for. One, someone did an excellent job of adding a holder for the display. The expandable arm mounts are about my only issue. Little bent and makes it wobble on mine. I didn’t learn they sell arms that will raise it till after, which isn’t a problem for me being able to print some risers. Learning how to navigate the screen and setting up your own dimmer/timer options is definitely a learning curve. Tons of YT videos on how to do so. You have to do it if you unplug it or if you loose power. Which I’ve had happen a few times and have to rewatch videos every time because I forget how to do it 🤣 Not sure if the upgraded model with the phone app makes it any easier, but when the day comes that this light might fail me, I’ll go that route and see. Overall I’m pretty impressed with it and my other Hygger products! Besides the white leds, my other favorite color is the light and dark blue.
