Looking for the best LED aquarium lighting? We’ve got you covered.

Lighting is without doubt one of the most important factors in creating a healthy, happy aquarium environment.

Read on to find out why lighting is so important, how it works, and which is the best LED lighting you should buy for your aquarium…

What Is Aquarium Lighting?

In a nutshell, aquarium lighting is any type of artificial light used to illuminate the interior of an aquarium.

There are 3 main types of aquarium lighting available in various colors, light intensities, and levels of energy efficiency — some of which also serve to heat tank water.

Different types include LED lighting, fluorescent bulbs, and metal halide lighting.

This article focuses on what is possibly the best type of aquarium lighting available today — LED lighting.

Why Is It Important?

In their natural environment fish, aquatic plants, and other water dwelling creatures need light to survive and be healthy.

Plants require light for photosynthesis, and fish need on average between 8 to 12 hours of light per day in order to mimic the natural day and night cycle and to enhance color pigment, aid digestion, and attain peak health.

In salt water aquariums corals will die without light as they rely on a symbiotic relationship with a photosynthetic algae which needs light to photosynthesize and pass nutrients to the coral.

From a human perspective, lighting also allows you to see in detail exactly what is going on in your aquarium such as the health of your fish and how they interact and behave, create different aesthetics, and provide a wonderful ambient focal point in a room.

How Does LED Aquarium Lighting Work?

Highly energy efficient and with great longevity, LED aquarium lighting works by using semiconductor technology, which unlike ordinary incandescent bulbs means that they won’t burn out or get especially hot.

LED lights are usually installed in the hood of an aquarium, but if this is not possible they can also be installed externally at the top of the tank.

The majority of LED aquarium lights can be adjusted to different intensities to suit your needs.

Many can be used with a handy timer to automatically turn on or off when required, and some more high tech LED light systems for aquariums can even be adjusted as desired using a remote control.

Pros and Cons of LED Lighting for Aquariums

Pros

  • LED lights create virtually no heat so won’t alter delicate water temperatures
  • They can be used to mimic the natural daytime / night time cycle
  • As they are available in different colors LED lights can be used to create different moods within the aquarium
  • LEDs are highly energy efficient
  • Bulbs are durable and have a long life span
  • LED aquarium lighting is small and discrete
  • Some LED aquarium light systems are configurable, allowing you to add different colors or additional lights
  • Light levels can be adjusted dimmer or brighter
  • EDs are safe to use in an aquarium environment
  • Usually arranged in a strip, LEDS give excellent light coverage across the aquarium

Cons

  • LED lights tend to be more costly than other types of aquarium lighting, so require a higher initial budget
  • If you prefer to purchase an aquarium kit, LED lights are less likely to be included
  • LEDs may not be bright enough for certain aquatic plants

How To Install LED Lighting

If your aquarium doesn’t come with LED lights already installed — don’t stress.

LEDs can easily be installed in most tank set ups. Here’s how…

In a Planted Aquarium

Light spectrum is an important factor when choosing LED lights for a planted aquarium.

The light spectrum should include as many colors as possible to ensure that plants receive the right kind of light to promote the best possible photosynthesis, so full spectrum LEDs are the best choice.

Most LEDs work well for plants that require low levels of light, but if you want to have a wider plant choice it is best to choose LED lights that emit around 6000k to 6500k.

The number and size of LEDs you will need to install for your aquarium is dependent on aquarium size, depth, and type and number of plants you intend to grow.

The lights should be well distributed to cover the length and depth of the tank to ensure that all plants receive as much light as possible.

In a Reef Aquarium

When it comes to reef tanks, the right lighting is crucial, and finding the right balance can be a complex process of trial and error.

As with planted aquariums, LEDs that provide a full light spectrum are essential, and set ups that enable you to adjust individual color spectrums — such as red, violet, and blue light — are best as they allow you to fine tune the light that your marine environment receives.

LEDs should be installed the full length of the aquarium to ensure the best coverage possible, and lighting that can be angled to reach certain areas more intensely, or to let less light reach more cavern like areas, have the added advantage of giving a choice of light intensities for different coral types.

What To Consider Before Buying LED Aquarium Lighting

Size

The size of your aquarium dictates the size of LED lights that you will need to buy.

The larger the tank, the bigger the LEDs will need to be in order to provide good coverage and penetrate deeper into the water without losing intensity

Cost

Although they work out cheaper in the long run, LEDs can be pricey up front, so may not be suitable for small budgets. If you’re not sure what you can afford, set up a plan and budget accordingly.

Try to get the set up you want without going over your initial budget if possible

Energy Requirements

Compared to other types of aquarium lighting, LEDs are very energy efficient; however, not all LED lighting is made equal, and the better quality the bulb, the more energy you will save.

This is a particularly important factor if you have a large aquarium which requires lots of lights.

Maintenance

An aquarium light set up that is difficult to maintain is a hassle.

Whenever possible choose LED lighting which can be easily accessed for cleaning, is waterproof, and which allows you to change or add lights, and / or lenses quickly and with the minimum of fuss

Light Intensity

Different fish and aquatic plants require different levels of light intensity in order to thrive.

Choosing adjustable LEDs that can be dimmed or brightened will allow you to optimize light levels to suit the fish and plants that you intend to keep

Premium Features

For added convenience you may want to consider LED lighting with remote control features, and an advanced control panel which is easy to use yet allow s for things such as multiple color programs, changes in light intensity for different portions of the tank, and a range of timer options
