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

This is an excellent aquarium light. I have mine programmed so that the blue lights slowly fade from off to full brightness in the morning. One hour later the white lights fade from off to full brightness. At night the white lights fade to off first, then the blue lights fade to off. The light fixture is adjustable, so it fits my 90 gallon saltwater aquarium perfectly. It has a low profile so it looks great.

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.

Using this as an addition to my Current led . Now my anenome is out and happy as are my soft corals. This light would work well alone for live rock and fish and possibly corals like Kenya tree and mushrooms. Excellent additional light without breaking the bank. The timer instructions are vague but if you play with it you'll figure it out

Very nice like, my corals are happy 😊

Great light spectrum. Simple to install. Programming it was similar to my house’s a/c thermostat. Just need to hold down the cog, tap until you what you need to change is blinking, then + or - until you have the time, light strength, and sunrise/set during. I love you can program the intensity of both the warm and cool light independently, but you can have them both on at the level you want at the same time. It’s making my tank look great and supporting my corals and sea creatures!

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.

AMAZING LIGHT FOR THE PRICE!!! I am starting a new 40 Gallon tall saltwater tank and decided to try this light out and it works perfect the lights are high quality and so is the controller. I see alot of reviews talking about how the instructions suck or how hard it is to program, it maybe took me 5 minutes super easy. If you are hesitant use this review as a buy it.

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...

This is a great product for the price.

The light worked good in the beginning but stopped working after 2 months.
