What are the benefits of aquarium LED lights?

Regardless of whether we talk about a fresh or saltwater environment, the LED lights are an absolute must. LEDs are economical, efficient, and do a great job of facilitating plants and corals growth. If we talk about the fish and other aquatic creatures, most of them enjoy an aquarium LED daylight simulation.

Some fish and plant species prefer though lower lights, that’s why it is important to choose a dimmable LED lighting system. We never know when we might change our aquarium setup or its inhabitants.

The aquarium lighting systems offer a multitude of benefits. There are many options on the market to choose from, and we are reviewing below the finest of them.

What to consider when buying an aquarium LED lighting?

  • LEDs are much smaller in comparison to the traditional lighting, but they are way more effective.
  • LEDs are directional, so that they light specific objects in the aquariums, without missing any important spots.
  • LEDs use mixed lights such as green, red, blue, or white.
  • LEDs are by far cooler, more energy-efficient, and have lower heat emissions.
  • LEDs are a fabulous choice for aquariums, however, there are a few things to keep in mind when seeking the ideal LED lighting system for your tank.

How can we improve the lifespan of our aquarium LED lights?

Avoid using LEDs underwater. The LEDs are labeled as waterproof or water-resistant, yet do not use them underwater unless the manufacturer instructions specifically mention you can. Or else, the equipment might suffer irreversible damage.

Do not allow the LEDs to get hot. They should not be mounted very close to other light types such as metal halides. This will reduce the lifespan of the LEDs.

Do not allow water droplets to accumulate on the lighting devices’ surface. Keep a watchful eye for mineral and salt accumulations as they may corrode the lightning parts. The lights should be cleaned regularly.

When using LED lighting for reef tanks, one should be careful where the lights are installed, to have the proper height, otherwise corals might suffer. The LED light can cause shock to corals and bleach them. LED lights should be gradually introduced to corals and reef tanks.

Not only corals or freshwater plants, but the fish as well have particular requirements when it comes to lighting. While some species enjoy higher intensity lights, others prefer dim lights.

Therefore, thorough research should be done as well about the fish species you are planning to house, before purchasing the best aquarium lights for your tank.
