NICREW ClassicLED Marine Saltwater Aquarium Light, 20W for 18–24 inch Tanks

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.

The light is phenomenal. Very easy to program. My saltwater tank is really amazing now. As the day goes by the light changes just as the sun does. Amazing light.

I like the brightness and the programmability of the light. Great price. Now we just need to see if it lasts.

Very nice light has lots of different options to setup up for coral or just a regular light also has a timer to setup you can adjust the amount of blue light to fit your needs. Would purchase again. A+

This is excellent with beautiful night and day cycle. I will try to remember to update at a later date.Note: Pressing the stars for the review was difficult. I had to press them 1 at a time, instead of automatically just selecting my choice.

Great for my saltwater reef tank. Corals appear to be thriving in the wide spectrum of color provided by this light, the blues are perfect for showing off the colors of them. I enjoy the easy with which to set up the timer and the sunrise and sunset setting and that the brightness is adjustable to meet your needs.

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.

I ordered this light in late July for my 75g aquarium, and wanted to give it some time before leaving a review. There are definitely some pro’s and con’s that wish I would have known in the beginning.Pro’s: fairly simple to setup and understand. Very budget friendly pricing. They have a very low profile, light weight, and sit super close to the aquarium creating a more pleasing look. The sun up/down feature is really nice and soothing to watch. Ultra quiet and don’t give off much heat. Honestly, these would be great for someone just getting into the hobby that doesn’t want to put a large financial investment into lighting.Cons: for a saltwater aquarium they really aren’t all that bright. At first I thought they were, had a sudden algae bloom and realized they were set to 100% blue and white, but after adjusting the blue/white levels to 100% blue and 40% white the PAR levels these lights give off isn’t bright enough for most corals. Only about 95 at 4 inches below the surface. They aren’t waterproof, which makes no sense, so I would suggest putting some sealant around the edges to close things up and give the light the best chance at surviving salt buildup and the occasional splash. The biggest con is that after six months of operation, something caused the controls for blue/white to switch and now to adjust the blue spectrum I make changes to the white. This isn’t a good sign for quality and durability. If you’re doing a FOWLR aquarium these are definitely the way to go. If you have a reef tank in mind, want to house anemone’s, or have variety in your choices then look elsewhere. Already planning to replace in the near future.All in all these are just “okay” at best. Will they light up an aquarium? For sure. Will they support corals? Yes, but only very low PAR species such as certain encrusting LPS and they’ll have to be in the top half of the aquarium. Be sure to have a plan as to what you’re wanting to house to avoid unnecessary spending or not having the right levels for the right species.

After 1 month 7 days it stopped working..

I have a 72 Gallon Bowfront aquarium. It’s 4 feet wide and the 1 light seems to light it up very nice although I’d be really happy with two.The timer functions can be a little tricky at first but after setting them it’s a really nice light.I did get it on a flash sale for $10 cheaper so I’m happy with that price point.

The brightness was good (sunrise/sunset) features are easy to setup. Good for starter, the price was fair enough. Not sure how long it will last (just started using it - i'll update if i see something interesting). I would like to give this product a 5 star, BUT the glass was broken when I unboxed it (pics attached). I believe it was during the delivery. So over all I will rate this porduct and the shipping 4 Stars... happy with the purchased even thought it was broken...

Pas défectueux , convient a mes besoin . Un peut difficile à comprendre comment le programmer . Instruction pas très claire et surtout juste en anglais .

Light is easy to use and instructions are easy to understand. Looks great on my 150gallon tank
