NICREW ClassicLED Gen 2 Aquarium Light, 18 Watts, Dimmable LED Fish Tank Light with 2-Channel Control, White and Blue LEDs, Size 24 to 30 Inch

Update to previous review. After responding to the requested technical testing and submitting a video. Full refund was issued. And again, great tank light, my favorite. I just have bad luck with it.I can not recommend this product. Great light when it works, otherwise garbage. Folks, it simple to set up and use, bight lights, dimmed lights, timer and then one day nothing! No power, no reason, same power strip, everything else plugged in and working. But here's the absolute worst part: this seller will send you a 2 page long winded list of demands plus sending them a video to prove its not working. Really?! They think I have nothing better to do than make false claims about a product failing yet again. You insult your customer? This is a difficult seller and an unreliable product. I do not recommend this seller at all.

I'm about 2 years into being an Aquarist and received a 30 gal tank and supplies from a neighbor who hadn't used it in many years. It had one of those traditional black plastic hoods with bulged section for the fluorescent tube light. It was fine, I was just starting out and it didn't cost me much to start the hobby. I enjoyed it except the one annoyance of not being able to use a timer with a fluorescent light. So having to turn on/off all the time and sometimes being out my fish spent some time in the dark until I came home to put the light on.So my search began recently after seeing so may nice online pictures of pristine aquariums beautifully lit. I first searched for complete LED hood sets to replace what I had, but all seemed cheap with mixed reviews. Then started seeing these light bars for tanks and wondered how those work with hoods. Then progressed my search onto glass tops that fold and this light bar sit over one section. Not bad I thought. Ordered this light and glass top only to find the glass top is like a 1/16th too wide to sit inside the tank opening on the ledge. Damn!Then remembered my old tank hood actually separates from the Fluorescent light part and reveals a glass window. Well this light bar fits right over that perfectly and rests on the edge of tank with it's extendable support bars.WHAT A MAJOR TRANSFORMATION!!! It's like a new aquarium and I am newly enjoying the aquarium. Get rid of your fluorescents if you still have them! Wonderful brightness with blue mood settings, mix of white/blue, just white and dimmable as it says. So nice.So what about my timer dilemma? It has a 8, 10 and 12hr setting. So I set it one day expecting it to go off on its own. It does. But viola! It also comes back on again at the same time next day you turn it on prior day! So a complete timer all by itself now comes on at 11am and goes off by itself at 11pm, with no other plug-in timer needed.Want more?? Well how about this! It is fish friendly for those slow morning risers and nocturnal type fish, cause it comes on dim first then brightens to max on its own. Opposite at night with it going dim to blue for a while before shutting off. TOTALLY AWESOME!! LOVE IT!! and Highly recommend this product.Looks like good quality to me and longevity I can't say at this time. But I am super happy I bought this product!!Well designed and thought out. Has re-energized by aquarist hobby mood!

I love Nicrew lights. This light is really nice and works great. It has 5 light adjustments of white and blue, has a timer for 8, 10, and 12 hrs., and fits perfectly. I have 3 of them and switched to a different model with other colors. Highly recommend.

The media could not be loaded. Update: Well, the good news is the white lights on this system are still work so my plants will survive, and that's the majority of this lighting system. The bad news is the blue lights failed and now won't turn on at all. I don't know why, but they just won't turn on which is frustrating! I haven't had them that long [two months] so it's really disappointing. I think the multicolor systems do better, but I wanted a brighter light which is why I added this. Hopefully, this is just the ballast they sent me. Either way, that's way too short of a life span.I am using this with two other of Nicrew's LED lights. I have the planted tank ones with the colors. I added this one to brighten up the tank a bit and it really made all the colors pop. I recommend using a mix of their lights. The ones with blue red and white for plants work great but I need some blues. This light has two channels and you can select the brightness of the blue or white light. I put it at max and put it in the middle. I added the ones that were more like 6700's on the opposing sides to add the red lighting. I have a 120 gallon tank and the plants are liking this mix. Also, I get a barely visible shimmer effect with this combination. If you like planted tanks, use this one and one of their NICREW ClassicLED Plus Planted Aquarium Light, Full Spectrum to get this effect. As other posters have noted, this is REALLY bright. It's missing the reds though so I think you have to do a combination. I've got two planted ones and this one. FYI - the dimmers they sell do work on both channels [those are the dial ones for the classic], but I don't see the point of doing that when you can just lower it hitting the buttons. Oh, the mode button is the off switch. I noticed this one has a sort of spring action to put it on the tank. I would recommend this going over a glass top. It's VERY close to the top. I'd say it's slightly shorter than the Nicrew Classic LED light. Value wise, this is fabulous. Very low amounts of heat. I had my mom look at the plants under these lights and she said my burgundy ones finally look nice as these lights brought out their colors [classic] and the blue from this one brought out the blues in my fish.

So- my pet store uses this brand and told me to get it. And it’s so bright but a size smaller than your tank. The legs will sit nicely on the glass top. My tank is 48 long. The light In the photo is 36. It’s plenty bright enough!! And in this photo it’s even dimmed a bit!! That’s my tip. Buy smaller than your tank this light is that good!!

Tengo una semana con la lámpara y funciona bien, me gusta, espero dure así por mucho tiempo

I love it, very bright and high quality for the money. 2 of the 18-24inch sets fit perfectly on my 55 gallon aquarium. Very aesthetically pleasing and I like that it’s flat, not curved like some lights out there. It has pretty bright white and blue lights with lots of settings, all work well. One thing I would want to change is, it doesn’t have an actual on/off switch, it just has different setting so I need to actually unplug it if I want it off. So far so good though. I just keep it on the lowest blue setting at night. Brackets were a bit difficult to put into the lights but it worked out well. Overall I give it a 4.5 out of 5. Very high quality but not completely perfect... in my opinion. Definitely worth the money and I would by from this brand again!

I like this better than the one I bought next to it from the pet store. It's brighter and I expect it will be great for my plants. I wanted to trade out my florescent for this one. As I wanted it to match on both sides. I am also using my florescent for plants. This is an excellent choice and I am glad I got it.

I really like the light for my 15 gallon tank. I do have a planted tank and this was the only light available in the size I needed. Time will tell if it is enough light. The only thing I don’t like is the timer. It is easy enough to use but I much prefer the timer on the Classic LED for planted aquariums. I was excited to see a timer can be purchased separately until I realized this is a 2 channel timer and it will not be compatible. I will one day buy a timer for this light to have it come on when the other 4 tanks come on. Aside from that the packaging and shipping was great and the light is working.

Excellent product. My light burned out in my aquarium hood and looking at the prices to replace it was incredible, if you could find one for your specific aquarium. You can set the lights on this and you can slowly dim it so its not just on and off. My fish are really enjoying it and I’ve noticed they are eating better and I don’t have left over food in my tank and when I turn the light on they know its feeding time. You have the option of different settings, colours etc. Really worth the money and it is adjustable so it fits on my aquarium. Love it!
