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

I upgraded to this light since my Dwarf Hairgrass carpet was not growing like it should have been with the cheap Hygger light I had on it. I put this on the tank, set it up with the easy-to-follow instructions, and it works great! Looks just like natural sunlight shining into the tank, and can get nearly as bright! It really makes colors pop! It ramps up and down for sunrise-sunset, you can set what time you want it to turn on, manually turn it on and off without screwing up your previous settings, adjust the brightness, and more! My only complaint (if you can even call it that) is the fact that it isn't water-proof like my other lights. That's fine, since I have a glass top on the tank I put it on, but even so, I like not having to worry about dropping my lights in the water. I definitely recommend this purchase, and it was surprisingly affordable for the design and performance I've seen thus far from Nicrew.

I have a 40 gallon breeder tank heavily planted with low tech plants like Anubis, crypts, some moss and a ton of guppy grass. Nothing incredibly care intensive mind you. For years I had used a very expensive ($150 at the time) Finnex planted plus 24/7. It was a great light that cycled through day and night lights to mimic the sun. However, it never seemed like enough and even though I have a low tech tank the growth was extremely slow. Loved the features and ease of use but disappointed with the light output Unfortunately it died on me. I needed a replacement quick so jumped on here and found this one. Some pretty good reviews, more basic in features, but with a wall outlet timer for $5, it seemed like it would work. Honestly, i've been blown away with it's performance. I've had it for close to a year now and it's been amazing. The light output is much higher than the other without seeming like it's blinding the inside of the tank. I don't currently have it raised at all, as it's only 2 inches above the water, and the plant growth in my tank has been outstanding. All my plants are generating new growth, the moss and guppy grass is exploding to where I have to toss handfuls of it every other week. Anubias, which are typically slow growers, are growing much faster, taller, and fuller than ever before! For $40... i'm super impressed. I'm not sure how this light would do with higher tech tanks, as in tanks that have more intensive plants, CO2, etc... but for most fish hobbyists I bet this would do the trick. I'm sure some of the negative reviews come from them breaking down quickly or arriving non operational, and unfortunately you take that risk with every "electrical" item out there. My $150 finnex light should have lasted a few years longer, but it didn't. So coming from somebody who, I would say, is fairly experienced in the hobby, this has been a great light.

Absolutely awesome!! Love the dimming feature. Great light for the price!! Pulled it out the box, made a slight adjustment to the length, plugged it in and set it up in a matter of minutes. Haven’t been this pleased with a purchase in a while.

I bought this light for use with my ADA 60P planted tank, which measures at just under 24" across (60cm). This light is decently built, but warns it is not water resistant. It was easy to set up with the sliding arms and works well with the timer I purchased separately. The light is pretty bright and should be good for medium and low light plants, but will struggle with carpeting plants such as HC, Monte Carlo, and Glossostigma. As I was dry starting my tank, I had some gloss planted in the foreground to carpet the bottom of the substrate. After a few weeks, while there was signs of a little growth, it was not the growth I was hoping for. No new runners, no explosive growth, just a little change in height. I ended up buying a Twinstar II 600S, and after running it for a week I noticed an immediate difference in growth. I now use this light in my 7 gallon nano tank and while it's a bit too big for the tank, it does work well and plants are thriving in it. It is a good value and overall a nice light, but just be warned that it's not a light for a heavily planted tank with demanding plants.

I bought the NICREW ClassicLED Plus 15W light for my 20-inch aquarium, and it’s been a fantastic upgrade. The light is sleek, easy to install, and fits perfectly on tanks between 18 to 24 inches. It provides a beautiful balance of daylight and moonlight modes, which makes my fish and plants look vibrant while mimicking natural cycles. The built-in timer is a game-changer—it automatically switches between lighting modes, so I don’t have to worry about turning it on or off. The adjustable brightness lets me fine-tune the lighting depending on the time of day or the needs of my aquarium. It’s energy-efficient and runs cool, which is great for maintaining a stable tank temperature. Whether you’re a beginner or a seasoned aquarist, this light offers excellent value and performance. My tank looks brighter, healthier, and more dynamic since I installed it. Highly recommended!

This is the second Nicrew light I have purchased for my aquariums. I originally purchased the Classic model for my 15 gallon tank and I liked it so much I came back and purchased a Classic Plus for my 56 gallon. Both are quality lights, well built with excellent output. This one is solid aluminum construction with extendable brackets - in fact it came with two types of brackets, one for thin framed aquariums and another for thicker frames which is very nice. It has a switch that allows you to go from full spectrum to blue only for a nighttime effect but I don't use it since all my lights are on timers. It does give a nice look though if that's what you're going for. A comment about customer service: I have been absolutely amazed at the quality of the customer service at Nicrew and will probably be buying products from them for a long time because of it. When I ordered my second light it arrived with a dead transformer. I knew it was the transformer because I plugged the light in with the transformer from my previous purchase and it worked fine. So I contacted customer service and asked them to send me a new transformer. Because the item is fulfilled by Amazon they aren't able to send out transformers without a light so they asked me if I would be alright with them sending me out a return from someone else's order - their logic was that it probably wasn't returned for a dead transformer so I could just take the transformer from that package and have a working light and this way they wouldn't have to waste an entire working light. That sounded like a good plan to me so I agreed it was worth the risk. They immediately sent out the package via UPS but UPS lost it. I eventually saw the tracking slip and it was terrible. UPS sent it all the way from Arizona to Virginia then from Virginia to Washington state, then to Ohio and Illinois and West Virginia before finally making it back to Virginia again. This was completely the fault of UPS - Nicrew had nothing to do with the lost package, but they felt so bad about it that they sent me a really nice algae scraper as a gift. Ironically when the return light arrived the person who had returned it hadn't bothered to put all the pieces back in so it arrived without the transformer I needed. I contacted Nicrew again and told them the plan hadn't worked, and once again they felt terrible about it, apologizing for wasting so much of my time (even though 90% of the wasted time was actually UPS not Nicrew!). At that point they decided to send me a brand new light and told me I didn't even need to bother returning the two lights they had already sent me - both of which worked, they just didn't have working transformers! So I now have three working lights, even though I can only plug in one at a time, and an algae scraper. Amazing! And through it all the Nicrew representative was very nice and quickly responded to all of my messages. They are in a different time zone so most of their responses came in the middle of the night, but they responded to every single email and even periodically checked up on the progress when I hadn't emailed them in a couple of days while waiting on UPS. Really a great experience despite the problems, I happily recommend buying this and any other Nicrew product you may be interested in.

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.

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.

Si quieras está lámpara para alto requerimientos de terrarios o acuario no la recomiendo debes de usar dos para ese propósito, aunque por lo demás es liviana, cómoda y funcional

Not as bright as I thought it would be. A bit dim looking.

Excellent results so far. My plants started pearling more rapidly as soon as it was turned on. Adjustability a great bonus!

Light is bright, easy to program and will grow low tech plants. Fantastic option if your not looking to spend alot of money on big brand lights

Por el precio no está mal pero definitivamente le falta potencia de luz, yo las utilizo para terrarios y no son lo suficientemente potentes para plantas de altos requerimientos, no las recomiendo si necesitas potencia igual son bastante incómodas para configurar
