NICREWClassicLED Plus LED Aquarium Light with Timer, 10 Watts, for 12 to 18 Inch Fish Tank Light, Daylight and Moonlight Cycle

I've just ordered and installed my second 30-36 inch unit. I've owned my first of these for approximately 2 years with no issues, and had it operating on a 29 gallon tank. I recently moved that unit over to half of a 125 gallon tank and purchases a second unit to light the other half. Between the two units, they are easy enough to synchronize and do a good job of lighting the larger tank. The sunrise and sunset function is perfect to mimic natural lighting for fish, and I've found that it's much more forgiving and flexible with regard to evening/night time feeding. The only drawback that I've found with this light is that during a power outage it does not retain the current time. It's strange that the program is retained, but the current time has to be reset. The programming is easy, and the instructions are easy to follow for setup. These generate lots of light with no noticeable excess heat. I have java ferns that grow under the lights, and I'm going to try some other plants in the future. There's no remote with these lights, but I've had lights in the past that came with remotes that went into drawers and never got used again. The programming function is attached to the power chord for each light unit, and is easy to operate. There's really no need for a remote operating function, and the timer functions great on these once they are set up.Overall, I would highly recommend these LED light units for aquariums, as I've had a great experience with them for 2+ years now.

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.

This is a great LED light for a 10-gallon fish tank. It has enough light to grow plants such as Valysneria and Amazon swords, but not so much light that you would need to add CO2 to the tank. Keep the light active for no more than six hours to avoid algae growth.I use this light on a ten-gallon shrimp tank. Frogbit and Salvinia float on the water. Those two floating plants grow very fast. I have to regularly remove about 50% of them every 3 weeks to keep them from layering. The growth is fast enough that these plants cover the top of the water and then they begin to layer.The build quality of this light is surprisingly good for this price point. Only time will tell how long they will last. I have been happy with them so far. They provide enough light to grow medium to low light demand plants. The fixture has been reliable. I have it connected to a mechanical timer. The light stays on for six hours each day. I stopped adding liquid fertilizer because the plants are growing too fast for my liking. This tank has approximately 10 freshwater mussels and an assortment of shrimp. I have Amano, Ghost, and red Cherry shrimp in this tank. Yes, I know the mussels and the Amanos will not complete their lifecycles in this tank. The former will need a host fish while the later will need brackish water. I do not keep fish in this tank.I can recommend this LED lighting system for fish-only tanks. It will also work well for tanks which only have medium-demand to low-light demand plants. It is perfect for floating plants. The angle of the light covers the surface area of a 10-gallon tank.This is a basic but solid light. It does not come with fancy lighting effects. It comes in daylight and that is it. You cannot create lightning effect and thunderstorms. But ask yourself if you really need those. I do not. It does not have a remote control. You will need to provide your own timer. Other than that, it is a great light for a 10-gallon tank.Highly recommended.

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.
