14W

I absolutely love this light, I purchased the 22W for 25-31inch long tank. My tank is a 20gal. 30in long, 12in deep, 12in high. I love that the brackets are adjustable. It fits my tank perfectly. The bracket though, the part that slides onto the light itself was very difficult to slide on, we had to hammer it in. Then the braket part that clips to the tank was not a perfect fit, so if you look in the photos there is a blue block my husband 3d printed inorder to have something between the clip and the tank to hold it in place. I included a time lapse video of the timed day time. There is a cool sunrise effect that takes 30 minutes to go from a dusk light to a bright light when pushed. I have this setting on the 12hr timer. The moonlight timer is really neat, as you can choose which color you want it. The day light you can't choose, it is just day light. Overall this thing functions perfectly and is a great quality. I just added it to my planted aquarium to help establish the plants before I add fish, so I am really hoping the plants take off and grow super happy. The plants look great under the light though. It is a really nice even distributed light! I will add, the plug ... The plug beeps. When the timers are set, their light flashes and when the light flashes there is a beep, that is a small beep, but if your tank and plugs are siting next to the couch where your ear is, you can hear the beep... And the beep is annoying.

This is a very good light. I have been using it for 6 months. The main full spectrum light works great with six levels of intensity. I usually keep it at about 3 or 4 during most of the day. The highest setting is exceptionally bright. The lower settings are good for the evenings. The moonlight settings work well. I usually set it for blue in the late evening and early morning hours. There are also 6 levels of intensity with each moonlight color setting. I wish the moonlight colors could go brighter, but maybe that's because they are meant to be moonlight. You do have to cycle thru the colors to get to the one you want, I always feel like I am freaking out my fish sort of, when I do that. The negatives: It was somewhat challenging to set up. I found it hard to attach the main body of the light to the arm. I did get it eventually. Also, attaching the light to my fish tank, took some creativity. I have a rimless tank. On the outside of the glass, I put a piece of bike tire inner tube and then a cut piece of wood paint stirrer, to cushion the tank glass from the plastic screws of the light arm when they are tightened. It worked out well. You also have to adjust how far you want the light to come out into the middle of the tank and that was somewhat of a delicate procedure. This all worked out, but I think this all should have been a bit easier to do. I never really used the programable daylight to moonlight and back settings. The majority of the daylight is the highest intensity setting which I think is over the top for all day. I wanted to review this light because I am very pleased with it so far. It lights up my aquarium beautifully and the choice of daylight intensities is very good.

This light is very bright and offers an excellent daylight color. It is likely too bright for a low-tech planted tank, so the dimmer options make this light perfect for pretty much any freshwater planted tank. The overall construction is quite nice, the mounts are decently sturdy, and the light itself is of nice, metal construction. The little plastic stopper on the mounting rail arrived damaged, although this part is mostly superficial it is so flimsy that this is to be expected. I use a smart plug for scheduling, so I have not used the timer settings, the controller for this light is sufficient for me. The mount for this light did not fit over the rim of my 40-gallon breeder tank. This could maybe be fixed (perhaps not very safely) by cutting the rim of the tank here where a lid would normally rest. I created my own 3d printed mounting brackets that allow this to mount nicely with the rim. If anyone is interested, it can be found on cults3d as "Hygger Clip On Aquarium Lights Bracket". Overall, I am quite impressed with this light, the build quality seems superior to a Nicrew equivalent, and the light output is substantially better.

If you have a rimmed tank you NEED a spacer for this light to attach to the tank. I cut some acrylic pieces which came out to be 10 mm thick. They really should upgrade the design because many people have rimmed tanks. The description says it fits a rimmed tank but it definitely doesn't work. Otherwise this light is awesome. It simulates sunrise, sunset and moonlight automatically. It is really cool!

I purchased this light for my 89 gallon above ground patio pond for the plants and to have light at night when I sitting on my patio,this little light does the job with know problem,highly recommend any of Hygger products, I've been using them for years and no issues

Great quality, good looking, and has so many features and timers that I don't need any other lighting accessory.

Funcionó 1 dia y ya no prendió más. La segunda pantalla bien para la potencia marcada para el producto.

First impression: really great light and nice features. But after connecting it, I noticed that the wire connection is kind of loose somewhere. Everytime I touch or simply graze the wire, the light come off and on and I have to reprogram the whole thing the next day. It’s not a big deal but quite frustrating. EDIT: I removed one more star as all the controls are dead now. I can’t even close the light with the controller I have to disconnect the wire. Unless it’s a problem with my unit, avoid this crap.

Je l'aime bien mais elle manque de puissance pour le même prix avoir su j'aurais pris une rampe un peut plus haut de gamme Elle fait ce qu'elle a a faire mais ces pas avec cette lumière que je vais faire pousser un fond de pelouse dans l'aquarium

Worked for approximately a year. I was previously happy with it. It began flickering and the 24hr cycle doesn't cycle correctly either any more. Contacted the seller and they mentioned there is only 30 days. If it was a cheaper light, I would just write it off and forget about it but this thing wasn't exactly cheap for how long it lasted. Not worth it...
