NICREWClassicLED Plus LED Aquarium Light with Timer, 15 Watts, for 18 to 24 Inch Fish Tank Light, Daylight and Moonlight Cycle, Brightness Adjustable

I've had many aquariums over the decades, and this is the best lighting unit I've ever had. It's a full-spectrum light with programmable intensity that is great for algae control while supporting live plants. And the moonlight setting is just too much! I've had mine for over one year, and it is performing like new.

So far it doesn’t sag like most other comparable lights, and doesn’t radiate heat even when being left on for 8+ hours. It’s considerably brighter than my tank next to it, definitely improving plant growth. I wish there was a dimming option, but I didn’t need a manual to use the remote so I approve!

Got this product 3 times now, theyre my most ideal lights for my plants and fish. I genuinely cant imagine my tanks with a different light, the timer feature is magnificent, the lighting is bright and adjustable. Theyre great for making your fish stand out especially if you have colorful fish. Ive dropped it once and it didnt break (thankfully) and i have spilled water on it by accident. Still works, very easy to use and place on your tank. The price makes it worth it.

I purchased this light in April of 2022. It appears to be a new revision. While the manufacturer's pictures on Amazon seem to match the product I received, the item and pictures do NOT match most of the reviews I see posted about this light, so hopefully this will be educational about what is currently shipping. Also, it has been a while since I've kept an aquarium and only recently am I setting up a new tank. I've never used an LED aquarium light before.This light has an integrated, hardwired timer controller that can control 2 separate channels or modes - one for daytime(?) lighting and one for blue lights. The LED array consists of white, blue, green and red bulbs. In timer mode, you can set one time period to turn on and off the daytime lights and another period to control the blue lights. I'm not entirely sure why I want to control the blue lights separate from the rest. Perhaps as a night light? You can also set 0, 15, or 30 minutes to phase in and out the light intensity - like a sunrise and sunset. You can control the intensity of each mode in timer mode, from 0 to 100 percent. This is all great. You can also turn on the full light or the blue lights manually and then return back to your program.However, there are some quirks - maybe even flaws - with the current controller. First - if you lose power to the light, the time gets reset to 00:00. Your program is retained in memory, but until you reset the time, the light will run on an altered schedule. Second, you cannot dim the light in manual mode. It only works at 100%. If you want to skip using the timer and control the lights externally via a timer or smart plug, you only can run the lights at full blast through manual mode. If the power cuts out while lights are on manually, they do come back on when power is restored. Third, and I'm new to LED aquarium lights so this might not be a flaw, however, when the lights are turned on in manual mode - all four color LEDs are used. But, when the daytime mode is triggered via the timer, only the white, red and green lights are lit. The blue lights are off. Note you can overlap the time period settings for the two modes, so maybe it is by design to have separate blue light control and you just run the two programs concurrently to have full RBGW spectrum lighting.To me, the loss of the correct time due to a loss of power is a problem. One work around would be to run the light through a battery back up, preserving the time and light operation until your battery dies. Second, you CAN use an external timer or smart plug. To do this, program the modes to both run for the full 24hours - 00:00 - 23:59. Set your intensities and don't bother with sunrise/sunset. Run this through your timer. When power gets cut to the led lamp - due to external timer or power outage, the lights go out. When power is restored, the lights will come back on after about 10 seconds - the clock will be at 00:00. They will come on at the programmed intensities. Both options work. Option 1 depends on an external battery backup (separate purchase) but preserves the sunrise/sunset feature. Option two depends on a cheaper outlet timer or smart plug but loses sunrise/sunset and the ability to turn on the lights manually through the LED lamp - you can use your smart plug instead.The light didn't come with a manual. None was posted to the Nicrew website that matched the new revision either. But Nicrew support was responsive to email requests through their website. I received responses overnight. They were able to provide a manual and answer some questions I had. Nothing in the manual details WHY or WHEN I want to use the blue lights though. I do question the spectrum chart they show on the box - is this spectrum only when all 4 light colors are running at 100%?I have not used this light on a planted tank yet, so I can't comment on plant growth. Heck, I'm not even sure how I'm supposed to run it - RGW or RGBW. All that being said, looking at some other lights in the same price range, its pretty great that Nicrew is offering a programmable timer. There is certainly value here. Add in a battery backup for the clock (let the lights turn off in a power outtage) and this would be a certain winner. Letting me dim the lights in manual mode would be an extra nice touch. Maybe in revision 3.

Very bright and clear. Easy to set up. Fits our 30gal perfect

Great value for a light that fits perfectly. I like that it can simulate the natural rise and setting of the sun. Super easy to install and use. No compaints!

Todo muy bien 👍

The media could not be loaded. I love this light! It fits perfectly on my 15 gallon aquarium and it’s not too bright. It was easy to assemble and the set up instructions were easy too. So far my aquarium plants have been thriving with it and I have the timer set so it will turn on and off automatically. The lights are high quality, the product as a whole is sturdy and easy to move if needed.The only thing I wish it had was a designated button for the light brightness! It’s kind of confusing to figure out how to adjust manually.
