Features

  • Upgrade VersionThis fish tank light is an upgraded version, with a larger size of lamp beads and a shiny surface that is bigger and more stable. It won't hurt your eyes when you look at your fish tank. The retractable stand measures a maximum of 6 inches and fits most freshwater tanks with and without lids. The aluminum housing with grooves provides excellent water resistance and heat dissipation.
  • 24/7 Natural ModeThe Aquarium Light has a lighting pattern that can simulate sunrise to night. By default,the aquarium lights change to orange from 6 am to 8 am, change to white after 8 am, and then gradually change to blue from 6 pm to 11:50 pm, remaining off the rest of the day. You can use the 24H button + 6 time point indication to set the first running time. By default, it turns on at 6 o'clock, and the whole time period can be advanced or delayed.
  • Customization ModeYou can set the light's color, time, and brightness according to your needs. There are eight color settings, white, red, green, blue,purple, orange, cyan, and cycle. In addition, you can set your running time to 6H/10H/12H, respectively. With five brightness levels, you can adjust the brightness from 10%-100% and long press for stepless dimming.
  • High-Quality Lamp BeadsThe fish tank light adopts high-quality 5730+5050 type lamp beads, so the light is more stable, with no strobe. With 85% of the color rendering index is close to natural light, bringing better light perception for fish and your eyes. The lamp beads are made of glue-filled technology, with an acrylic baffle to prevent water vapor from entering, making it more waterproof and extending its service life.

  • Great light, poor instructions, poor amazon customer service
Size: For 24~30inch Fish Tank
If you can get it programmed, this light is great. However, the design of the power cord inline controller, and the instructions for how to use it, suck. (Full disclosure: I have an IT background and consider myself a UX dweeb; I have a website devoted to the usability of medical software.) When I first got it, after reading the instructions, I was able to get it to the automatic 24-hour cycle. But then we had a several-hour power outage, and my wife found the lights shining brightly at 11 PM and simply pressed the power button to turn off the lights. This morning, I realized I needed to reset the timer for the 24-hour cycle. In the spirit of "if a door needs a user manual – even a one-word user manual – it's a design failure" I grabbed the inline controller and tried to figure out how to reset it. Press the 24-hour button? Did nothing. Press it several times? Did nothing. Maybe I need to press the 24 hour button and then the very flat 8 AM button? Nothing. Read the user instructions… didn't help. Looked on this page for more help… couldn't find any. OK, just press buttons at random to see what works. Finally figured it out. Press on/off button to turn unit on (essential) > press 24-hour button > wow, that "8 AM button" is a light that lights up! > press the 24-hour button a few times as those buttons (really lights) cycle through the day until I get back to 8 AM being lit > I'm back in business. **** UPDATE *** just a few days after purchasing I have upgraded my rating to 5 stars. The company contacted me about my concerns, right away, in a respectful way. I did offer specific recommendations for improving the user instructions, which they said they would use in the next revision of their instructions. They also offered a partial refund, which I declined, as I thought it would taint this review update. I will also add that now that I have discovered how it works, the user interaction design seems pretty simple. In UX terms, not very discoverable but very learnable and memorable. When the power goes out, and I reset the timing for the 24 hour cycle, it's really quite easy now that I know how. I did put a label on the aquarium as a reminder but it's really pretty superfluous once I showed my wife how to do it. It is a "see one, do one, teach one" sort of skill. But then, I found out that someone – not me – had requested a replacement unit. I had no problem with the unit, just the instructions. I received the replacement unit without my request and was going to give it away until amazon demanded I return the original. Despite an hour of trying, I was unable to contact amazon to let them know this was a spurious return; I would end up at a dead end with both the text chatbot and the voice chatbot where none of the options applied. One star for amazon.com's customer service. ... show more

I love this light! I don’t want to jinx it, but this light is bright and perfect! I’ve been using a lot of Nicrewlights for the last 2 years and decided to give this a try! Couldn’t be happier! I’ll report back in 6 months.

  • Everything the others aren't
Size: For 48~54inch Fish Tank
The media could not be loaded. I bought a similar item similarly priced recently that was not waterproof, and had many reviews that stated that condensation had damaged or broken them. This will not do on an aquarium, obviously. It had no timer. It had no adjustable colors. It had no brightness settings. It's power supply got hot (hot enough to potentially burn someone!) within a short time of being powered on, every time it was powered on. This light was an excellent solution to every problem the other light had. Waterproof, sturdy, adjustable colors and brightness, natural light mimicking cycle, multiple timer options, and the power supply/plug does not heat up. Only two days in but so far I LOVE it. I'll update if that changes. Also, the protection plan was less than $9 for 4 years. I am very pleased with this purchase. ... show more
