Led Aquarium Light with Timer, Submersible Aquarium Plant Light, Fish Tank Light with Auto On/Off, 3 Lighting Modes, Adjustable Brightness (26.8 in for 28-52inch Planted Tank), 14W

Works great, really lights up my 55 gallon tank ,easy to program. Definitely worth the price.

I really like this light because it’s submersible. It provides a very clean look without lights disturbing the clean lines at the top of the tank. Great features with a 24/7 timer to imitate dawn to dusk is really nice. The light turns on and off gradually so you’re not bombarded with light when it automatically turns on. I think this feature also reduces shock to the fish. The first light I had on the tank didn’t have a gradual light feature. When the light came on the fish scattered. The fish aren’t bothered by this light at all. It seems like they know feeding time is coming when the light starts barely illuminating at the beginning of the timed cycle. I’m getting another one for a different tank.

I needed another light to increase light levels in my heavily planted tank. This a good bright light that has the benefit of covering the full spectrum, simulating natural light. I would give it five stars except that the controls for functions are a bit confusing and I've yet to figure out the timer function fully. Seeing as I own half a dozen other lights that have similar functionality, you wouldn't think that would be an issue, but whoever designed this light's switching mechanism was trying to be different from the other guys (I'm guessing) and strayed from the usual path when designing functions and their controls. It took me a couple of days just learning how to turn it off and on (you need to hold down the power switch, merely pushing the on/off button makes it do other things) like I say, I've yet to figure out exactly how this light works despite my continued efforts to operate it. The light itself is fantastic and is just what the doctor ordered. Too bad I am having trouble setting the timer and find myself having to manually turn it off and on. I suspect that with the timer it has a fifteen minute period where it goes.from exceptionally dim to full brightness and then the reversal when turning off again but I'm not certain. I don't have time to wait and see if it's going to turn itself once the time is activated (if that's what it actually is, it's not exactly marked either) and either I somehow lost the instruction manual while I stalling or never got one in the first place. I don't recall seeing one but I assumed I didn't need one to turn on a light so I didn't check thoroughly that morning. I also found it a bit pricey but no more that the competition. I've gotten them cheaper but it's right on par with a majority of the competition. Aquarium lights aren't really all that cheap. All in all,.I am happy with the purchase with the exception of it's confusing controls. The quality seems good and it perorms as advertised or at least would if i understood how it worked better. I'm no amature and if I can'tfigure it out I'm certain there's others who are even more confused, but have to admit that perhaps the failing is mine and mine alone. The light is good and bright and apparently has more functions than I can figure out how to use properly. It is submersible and comes with a long cord. It was super easy to install on the underside of my aquarium lid, four suction cups being two more than necessary and quite effective.

I did not want an aquarium. I inherited it from my father back when he and my mom moved from their home to an apartment and they needed someone to take care of his fish. He was the one that always loved aquariums and having all sorts of fish. But once I inherited his fish, I've been having to care for fish ever since. I've gone through quite a few aquariums since then and a variety of lighting systems, from the old-fashioned vacuum tubes to LEDs, and I have to say this is probably the best aquarium light to date.The options for either strictly blue or a mix of blue and white lighting or just white lighting is a bit clunky to get used to, but, once set, it's great. The best feature has to be the timer, which allows you have the LED turn itself on for a certain time period - 6, 10, or 12 hours - and then it turns itself off for the rest of the day. Once set, you don't have to do anything to it unless the power goes out.The only downside is the suction cups, which has at least once slid down. Still, it's submersible, so there's no risk of electrocution to retrieve the light.In all, great light to get for your aquarium.

Great product many settings and very powerful adjustable lighting i got a smaller light for my 55gal and lights it up with ease id highly suggest it to others

I haven't had it fall down yet, but I do have to press the suction cups against the glass every few days when I notice them coming loose. Otherwise, seems to do what I intended: add more light for the submerged plants without burning floaters and emmersed foliage.

Works great .

It is used in a 55 gallon aquarium and gives it great light. I like the fade on and off timer. No more startling light shock for them. The blue is beautiful. I will be ordering another one for the blue moon effect.
