NICREW 20W Saltwater Aquarium Light, Marine LED Reef Light for Corals, Programmable Timer Controller, 18 to 24-Inch

The NICREW ClassicLED Marine Aquarium Light is praised for its bright lighting, easy setup, and budget-friendly price. It features 445nm and 460nm blue, 10,000K white, and RGB LEDs, creating an ideal color combination for the saltwater environment. The light comes with a dual-channel timer to adjust the lighting spectrum, simulating a gradual sunrise and sunset.The product supports a variety of marine life, including saltwater fish, live rock, soft coral, and LPS corals. It's available in multiple sizes with extendable brackets, making it suitable for both rimless and framed aquariums. A glass or acrylic canopy is highly recommended to extend the life of the unit by preventing moisture from affecting it.Users noted the light's incredible brightness, with one commenting, "Everything in my tank is glowing." Another stated that the setup was straightforward and the light selection perfect. The product's timer function, though yet untested by some customers, is also viewed positively.Some users, however, mentioned that the light needs to be sealed to prevent moisture from getting in, and that if power goes out, the timer needs to be reset. But despite these minor inconveniences, most customers feel the product is worth the price.It's also worth noting that the product has been positively reviewed by customers outside the U.S., particularly in Canada. Canadian users found the product worth the price and praised its brightness and sunrise/sunset features.Overall, the NICREW ClassicLED Marine Aquarium Light is a highly recommended product for those looking for quality aquarium lighting at a reasonable price.UPDATE: lasted over two years before LEDs started to die on the left side. Im ordering another.

So far so good light works great and it can take at least two drops to a ceramic floor.

So this is a great light as far as functionality. I allows you to set a timer, the I intensity of the LED on different channels and even has a sunrise and sunset option. However, if you loose power, the time is reset. In my recent experience, the other configurations were not lost. Not sure why time needs reset but the rest of my configuration was good.This has great configuration options. It’s pretty customizable for the price. Make sure you read the short instructions ahead of time so you understand the codes and the button presses.The white LED is not exactly a high white. The white alone without the blue is really ugly. I always have the blue on with the white. I actually lower the white intensity a little to about 50% to give the tank a little more blue throughout the day. I did notice the white channel has some green spectrum mixed in which might cause this.The white and blue are on different channels so you can have a timer for the white and a separate timer for the blue with different intensities.My favorite part is the sun up and sun down uptown. There is a setting to turn on the lights fully, or use the sunrise-sunset option. Sunrise and sunset each are hardest to 15 minutes.My setup turns on white at 50% intensity and blue at 100% intensity late morning. The white fades off early evening for an all blue moonlight and then a couple hours later, the blue fades off to night.I would buy again at this price. I would also request the manufacturer to put brighter white LEDs for a better white color.

I initially bought this as a backup for my reef tank when I had a Fluval light. However, I later bought an AI Hydra 32HD and no longer needed this. I did end up setting up a freshwater tank and decided to use this. My plants love it and it is fairly bright and customizable for the price. You can control both the white and blue channels individually in 5% intervals and can customize the ramp up and ramp down time in intervals of 30 minutes. You can only select one ramp up and two ramp downs, with one being made for blue light night time viewing. Despite this, it is still an exceptional light and even my red cryptocorynes have become a deep shade of red, even without a dedicated red channel. I definitely recommend!

Box came in a little beat up but it’s what’s in the box that matters. Light is great, build quality is great doesn’t feel cheap at all. Corals are loving life with the new light so if they like it I love it.

Poor product I woke up this morning to the light not working and the screen control panel was dripping with water. How do I get a replacement for this product?

I just got it. I opened it and tried to set up but I couldn’t figure out how to set the clock. In all fairness I only had a few minutes to mess with it so I’ll read the directions again and give another try. Will update

This light is absolutely great especially for the price. I bought this light in February and the only ones happier than me are my corals. I’ve been in and out of the aquarium hobby for over 20 years, and this is the best LED value price light I’ve ever used. It runs pretty cool, it is quiet no humming or anything, the control’s is intuitive. It has a ramp up and ramp down feature (F1) I believe they call it. You can set a timer for both blue and white channels. I set it for my blues to run 3 hours in the morning then blue and white for 8 hours then blue for 3 more hours. My fish and corals love it. My Frogspawn is growing and splitting into 4 heads, my hammer seems to grow daily, my zoanthids are multiplying and my bubble tip anemones are getting huge, although I do feed them. I would by this light again any day.One caveat. All my corals are in the top 12” of water, and they are softies or LPS which should be ok under less light than SPS. So I don’t think this light can handle SPS. But it certainly makes my LPS happy.I did just add an octospawn down about 18” and it’s doing ok but doesn’t seem as happy as those up on top. I’ve only had this one about 2 weeks so hurt is still out, and of course many factors are involved besides lighting.This is a beautiful light. Highly recommend.
