Full Spectrum: The fish tank light contains 6500 K white light, 450 nm blue light and 660 nm red light. LUX: 2500; PAR: 55; CRI: 90. The vivid lights can reproduce the real colors of objects to relieve the visual fatigue, and thus improve the comfort of the environment.
2 Lighting Modes: Short press the M button repeatedly on the fish tank light to switch between daytime and night modes. Hold the M button for 3 seconds to turn all lights off. Simulate natural sunrise and sunset to energize your fish and give them a sound sleep.
6 Intensity Levels: Daytime Mode (all lights are on): Press the W button to control the brightness of white and red lights and press the B button to control that of the blue light. Night Mode (only blue light is on): Press the B button to adjust the luminance.
For 12″ to 18″ Tanks: With an extendable bracket (min length: up to 11.5″; max length: up to 20″), the LED aquarium light always stays steady on the fish tank. Work best on tanks of 12 to 18 inches long.
Heavy-duty Design: FCC-certified aquarium light. The clear board is strictly sealed with silicone to keep out moisture or droplets. Solid aluminum shell can accelerate heat dissipation. The long-lasting bulbs and ETL-certified adapter ensure safe and continuous lighting.

Great tank light!
Great little light. Love the timer function and all of the customization you can do for such a good price! Doesn’t use a lot of electricity, high power, easy to set up, and easy to control. Great light coloring and options!

Excellent LED lights for aquariums
Excellent LED lights for aquariums. They have multiple colors, provide good illumination, and make the aquarium look much more beautiful. The colors are vibrant, they don’t bother the fish, and they are easy to install. Very good quality and stable performance. Highly recommended.

Great lighting
Have had and been using for months and still working well so already good lifespan. Has perfect variance in light setting for terrarium hermit crab setup. Helps with the natural circadian rhythm of the crab. She follows the artificial light as if natural sunlight. Love the remote control which where it turns itself on and “rises/sets” like sun. Absolutely worth the price. LED makes an energy efficient option also. Easy to install even on our older aquarium top.

Good color and bright but only lasted one year.
Worked great for about one year. Was nice and bright and fit well. Minus one star for short life and that’s generous I think. Probably should be minus two stars. Now it just barely comes on and flickers and sometimes won’t come on at all. (It’s on timer). Has definitely gotten moisture inside and can see the corrosion around the LEDs and traces.

Amazing product !!
I’m really happy with this aquarium light. It’s very bright, and the brightness is adjustable, which is perfect for different setups. The blue light is beautiful and makes the tank look amazing. It’s lightweight and the adjustable fit makes it easy to install. Overall, really good product and great quality. I definitely recommend it.

Perfect and insanely cheap
Works with my Kasa Wi-Fi plug timers, #1 most important thing (in other words, has “memory” after power turns back on).Fits both my 2.5 gallon (12 & 3/16″) and 5.5 gallon (16 & 3/16″) Aqueon glass aquariums perfectly.Light can be set bright or dim, I really needed that dimmer. I have yet to be disappointed in any Pawfly products.Cord length could be a touch longer would be the only downside, but it worked for me. Could see it being an issue if aquarium for some reason was not set up very near to a plug… But I’m not sure why you would do that in the first place.For the price I got it for, it’s unbeatable.

Great little plant light—plants are thriving!
I’ve had this light in my tank setup for over six months, and it’s been fantastic. I Velcroed it to the inside top of my tank lid, and it’s helped my plants really thrive. I love the different functions—full spectrum, blue light, and the built-in timer—so I don’t have to adjust anything manually. It’s small but powerful, easy to set up, and completely low-maintenance. Definitely a great addition for anyone looking to boost their aquatic plant growth!

An explosion of algea growth.
The light is very bright. However I find it difficult to use the timer and the shades of lighting. It will definitely cause algea to grow !! Would not really recommend.

I recently purchased the Pawfly 21W LED Aquarium Light for my 36-inch fish tank, and I am beyond impressed! The full-spectrum lighting (white, blue, and red LEDs) makes my aquarium look absolutely stunning—my fish and live plants have never looked better.What I Love:✅ Perfect Fit & Extendable Design – The adjustable brackets fit my 36-inch tank perfectly, and the build quality feels solid.✅ Day & Night Modes – The daylight mode enhances colors beautifully, while the blue night mode creates a calming moonlight effect.✅ Adjustable Brightness – I can fine-tune the light intensity, which is great for my plants and fish.✅ Paired with a Smart Plug – By connecting this light to a smart plug, I automated the schedule (on/off at sunrise/sunset), making maintenance effortless!Final Thoughts:This light is affordable, high-quality, and packed with features—way better than more expensive brands I’ve tried. The smart plug integration takes it to the next level for convenience. Highly recommend to any aquarium enthusiast!10/10 – A must-have for your fish tank! 🐠💡

Hay que dejarlo prendido siempre o desconectarlo de la corriente eléctrica, lo que es incómodo para hacerlo diario.La iluminación es buena.Opción aceptable para su costo.

Absolutely love these lights! I love how you can adjust the brightness, and my plants love the lighting!!! Only downside I find, the brackets that hold the light up, can be a little flimsy as you adjust them.Overall, I would buy again though!
