Aquarium lights are crucial when it comes to maintaining healthy aquarium fish, and choosing the right ones for your aquarium is no easy task. Aquarium lights come in a variety of types including fluorescent, incandescent, and LED. Fluorescent lights emit a yellowish-green light that is ideal for planted aquariums, while incandescent lights emit a white light that is ideal for saltwater aquariums. LEDs are the newest and brightest aquarium lights, using less power than fluorescent and incandescent lights.

Aquarium lights come in two varieties: incandescent and fluorescent. Incandescent lights are the oldest type of aquarium light, but are the cheapest. Incandescent lights have a short lifespan, and need to be replaced about once a year. Fluorescent lights are more expensive but last much longer. The lifespan of a fluorescent aquarium light depends on the model, but can last up to 10 years.

While aquarium lights come in a variety of types, all aquarium lights have three basic functions: providing light, heating the water, and filtering the water.

Aquarium lights with extendable arms are a great option, allowing you to adjust the height of the light to position it exactly where you want it.

Here are the best aquarium lights with extendable arms of 2022:

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.

AQQA Aquarium Light

by AQQA

Full Spectrum Brightness,Sutable for Freshwater Plantsfull specturm ratio for aquarium,make aquatic plants more comprehensive photosynthesis and color development, which is helpful for plant growth and viewing.

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 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.
