NICREW 48W Saltwater Aquarium Light, Marine LED Reef Light for Corals, Programmable Timer Controller, 48 to 60-Inch

Great light. Set up was easy. Timer works great. I really like the blue light and the moonlight effect. Some people had commented that setting the times was hard. It was straight forward and easy. Very happy with this light. Havent tested par so not sure if it would work for corals, but works great for lighting the tank.

I am really enjoying this light on my 100 gallon saltwater aquarium. It is about 1/3 the price of the name-brand unit it replaced and works every bit as well. And it is bright. Very bright. I have a fish-only tank and don't need to turn it up past 20%. The controls are easy and intuitive, and I like the settings for day and night lights. Thumbs up!

Purchased this 30"-36" light for my 40 gallon breeder saltwater setup with little expectations. Anticipated swapping out with a better light once I introduced corals. I am 2 weeks into introducing a green star and several Zoa's and am honestly impressed. Color in the corals are bright and see visible rooting/polyp growth already.4 star review only because spectrums are too vivid and almost shutter to the human eye. Just not quite lifelike. Running 33%W, 80%B in daytime(9 hrs); O%W, 5%5 Moonlight(2 hrs.).**Don't listen to reviews saying remote is impossible and junk. These people likely didn't graduate grade school. Took me 3 minutes. Longetivity..... TBD only been running 3 months, but no issues yet****

It's just excellent

bulletproof light, been sprayed, soaked, dunked, etc with saltwater and still going strong. got one led that is finally starting to go out, but just dont submerge it in saltwater and you wont have that issue.

This is an update to my earlier review.I contacted Nicrew regarding the difficulty that I had programming this light. They responded within about 16 hours. Fair enough. They provided me with a video demonstrating the programming process and steps. I placed my iPhone beside the controller and followed the steps illustrated. I did this repeatedly for about an hour. I have given up. I am usually very good at programming controllers such as this, but this one is beyond me. I looked further into reviews for this device and discovered that I am not the only one who has experienced this difficulty. I am going to throw this Nicrew marine aquarium light out. I will find a store locally and replace it with another light from another supplier that is NOT NICREW! I am extremely dissatisfied. The customer service was okay, about as much as could be expected from an online seller. There’s not much they can do with an inferior product.Previous review:I have had this light for about 7 weeks. It’s difficult to program, has limited capabilities and poor instructions. I have found that I can only really operate it in manual. Unlike the claims, it does not gradually ramp up or down like it is supposed to do. In only the on position are the lights bright enough for healthy coral growth. I would NOT recommend this light for an aquarium. I will try to find an alternative.

The reaction of my corals that I started again was incredible, they love the light and automatically opened up.

Light was alittle hard to program and I was not able to complete cycles on light that I wanted.
