for June 2023

The AQQA 11W-45W aquarium LED light is bright enough to give plants a rounded, lush look, and it's bright enough to light the entire tank without flooding it. The four different light settings let you control the light's intensity, and the light output can be adjusted from 11W (low) to 45W (high) in 30% increments. The AQQA 11W-45W's LEDs have a lifespan of 50,000 hours, and it has a manual timer function that lets you set the light to shut off at night and turn on in the morning. The AQQA 11W-45W is easy to install, and its light output is evenly distributed and uniform.

The hygger aquarium light is a great aquarium light for fish tanks 18 to 24 inches wide. It's bright enough to provide enough light for plants and fish to thrive, but not so bright that it blinds you. The light has three color modes: white, blue+white, and blue. The white light setting is bright and look very sparkly, while the blue+white setting is subtle and nice for plants. The blue setting is bright enough to provide plenty of light for fish, but too bright for plants. The hygger light's 5730 LEDs have lifetimes that are longer than most LEDs, which is reassuring. The light's dimmer is responsive and makes it easy to change the light's brightness. The hygger light also has an external controller that lets you adjust the light's brightness and lighting time. The hygger light has an adjustable bracket that lets you move the aquarium light to wherever it's needed. The hygger light is also very sturdy, and the light's bracket and lamp head are made out of non-corrosive aluminum.

The FUJIWAY Aquarium Lights LED Fish Tank Light with Aluminum Alloy Shell Extendable Brackets, Waterproof Full Spectrum White and Blue LED, for Simulation Sunrise and Sunset Function is a slick, well-designed light. It's bright, it casts wide, even light, and it's easy to set up. The brackets are metal, and the light can extend up to 54 inches, so it's compatible with most aquarium tanks. It's also worth noting that the light shuts off automatically after 12 hours, so you won't have to worry about forgetting to turn it off. That said, the light isn't suitable for all aquariums, and not suitable for aquariums with rimless glass. This light casts a wide, even glow, but it's too dim for fish to dart around and for plants to grow, and it's too dim for most settings. For larger aquariums, the FUJIWAY Aquarium Lights LED Fish Tank Light with Aluminum Alloy Shell Extendable Brackets, Waterproof Full Spectrum White and Blue LED, for Simulation Sunrise and Sunset Function is a great choice.

This LED aquarium light kit is bright, easy to install, and well made. The bracket is long enough for a 37-inch tank, and the light itself is bright enough to illuminate a tank in a noticeable way. The remote is simple to use, and the light has 16 color settings and 4 different modes, including flash, strobe, fade, and smooth transitions. The remote is small enough to fit into a pocket, and it's waterproof, so you can easily control the light from inside or outside your tank. It has a dimmer, and it offers options for different colored lights, which enable it to create different lighting effects. This is the brightest light we tested, and the 4-mode options allow you to set what light you want and when you want it. According to the manufacturer, the RGB LED aquarium light kit has 140 lumens per watt, which puts it near the top of the list. We also like that the LEDs in this light are super bright, and the lights are white, not yellow, like some other lights we tested.

The Joyhill LED Aquarium Lights are versatile, bright, and easy to install -- and they last for years. They fit any 30- to 50-inch tank, and because the brackets are removable, they can also be used in tanks 20 inches or less. The lights can be set to blue or rainbow color modes, and they can be dimmed with the included remote. The brightness of the LEDs is adjustable, and the light has a very wide range, so it's suitable for tanks of any size. The lights are waterproof, so you can use them inside or outside. The LEDs give off very little heat, so you can use them in any weather conditions without worrying about overheating. The lights come with a power supply and a remote, so they're ready to use right out of the box. The remote is programmable, so you can set it to turn on at a preset time, and the light can turn off on its own after 30 minutes. The lights can also be set to a timer, which is ideal for setting the light to turn on at night and then turn off in the morning. The lights come with 2 extendable brackets, so they're more versatile than our other pick, which has only one bracket. The brackets are adjustable, so they're easy to use. The lights are very bright, so there's very little light loss when adjusting the brackets. The lights come with a 1-year warranty.

The MingDak LED aquarium light has a bright, 6500K white-light, plenty of LEDs, and two brightness settings. The light is relatively bright enough for most aquariums, and it's incredibly efficient, using much less power than other lights. The fixture is relatively small and easy to install, and the included bracket is adjustable, so you can position the light wherever you want. For the price, the MingDak LED light is an excellent buy, and it's especially good value if you're looking for a light that you can position above your aquarium. The mounting bracket is also great for mounting other lights, such as a florescent strip, on top of the aquarium.

The MQ 7W RGB Aquarium Light from MQ Innovations is the best aquarium light for entry-level and experienced saltwater hobbyists alike. It is powerful, easy to use and looks great, and it provides plants with just the right amount of light but doesn't harm them. Its light output and color spectrum closely mimic the natural sunlight, which allows plants to grow well (and look great) without harming them. The MQ 7W RGB has 12 white lights and 24 RGB lights. You can adjust the lights independently, so either set of lights can be on at once. The 36 LED lights provide excellent coverage when placed 24 in. from the tank, and with their 50,000 hour lifespan, they should last for years. The other main reason the MQ 7W RGB is the best aquarium light for hobbyists of all levels is its remote. The remote is compact and easy to use, and it controls all of the lights as well as the aquarium pump and heater. The remote also has a built-in timer, so you can schedule the lights to come on at specific times. The MQ 7W RGB is easy to set up and is great value.

This light has lots of great features, but a few things keep it from being the best light we tested. First, the 23W model we tested is a little on the small side, and it may not be suitable for larger tanks. Second, the light doesn't emit much heat, but the heat it does generate is noticeable. Third, there's no built-in timer, so you'll need to set the light manually. (The 24W and 31W models do have timers.) Fourth, the 7.5ft power cord isn't long enough to reach most aquariums, but AQQA sells a longer power cord separately. (AQQA also sells a 31W model, but we didn't test that one.) On the other hand, the light has a very nice, bright, white color, and the LEDs don't produce any noticeable flickering or buzzing. It's also very bright, so it's suitable for both small and large tanks. The lights are easy to install, and the light extends up to 54 inches, so you can place it close to your tank. The lights also have a remote control that can operate the lights from anywhere in the room. The remote control is reasonably priced, so it's a worthwhile accessory.

The Wate rebirtth LED Aquarium Light is an impressive tank light that has several unique features. The bracket is adjustable, so the light can be positioned to hover over the tank, or it can be angled down to illuminate the entire tank. The LEDs are mounted on a separate circuit board, so they do not emit heat, and the circuit board is isolated from the metal bracket, so it does not heat up. The bracket is waterproof, so the light can be used underwater. The LEDs are full spectrum, so the light provides natural-looking light for healthy plant growth, and the blue LEDs help to induce color in coral and plants. The The light has four brightness levels, and two dimming modes: fixed and fading. The sensor detects the aquarium's temperature and automatically adjusts the brightness. The light is easy to install, and it comes with two brackets, so the light can be mounted in three different positions. The bracket is very lightweight and easy to install. The bracket can also be mounted to the side of a cabinet or bulkhead, so the light can be positioned away from the tank.

The Bright Classic LED Aquarium Light is inexpensive, its bright white light is ideal for plants, and it comes with an adjustable bracket so you can place it pretty much anywhere in your tank. Unfortunately, its light output isn't as bright as our other recommendations, and its colors aren't quite as strong as those lights. The mounting brackets, though, are easy to use and can be repositioned as needed. The lights are also easy to clean, and you can use different colored LEDs for different colors of plants. The Bright Classic LED Aquarium Light is also rather dim, which makes it suitable for low-light levels. But it can be expensive to buy multiple LEDs. And, while the light does come with a two-year warranty, there aren't any replacement parts available.
