Best LED Aquarium LightingMost of us care for our pets unconditionally, and the same goes with your fish as you strive to create a fantastic habitat. One great way to ensure their health is optimal is to provide them with the best LED aquarium lighting you can.

These unique aquarium lights are designed specifically to enhance the life of plants and corals, which have become increasingly popular over and above fake plants (this is a good thing)! After all, plants and corals need light to grow and photosynthesize, but you can’t leave a glass box full of water in direct sunlight. Such LED lighting is suitable for most types of fish, both freshwater and saltwater.

LED lights are manufactured to support aquarium life by enabling conditions under which plants and fish can thrive. They provide the ideal temperatures and lighting scenarios for them. Though the LED lights have practical functions, they’re a solid foundation of the modern aquarium; aesthetics. Special lights enhance the coloring of corals, natural plants and even the freshwater fish or saltwater fish themselves.


Areas to think about:

The LED aquarium light market is huge. The fishkeeping industry is extremely large and lighting companies almost always have an aquarium LED range. But not all types of lighting are suitable for aquariums. There are some key areas to think about before you buy the best LED aquarium light for your tank. Let’s go through them one by one so you can make an informed decision.

1. Size of the your fish tank

This is an obvious one for LEDs. The first aspect to consider is going to be the size of your fish tank, depending on how large or small your aquarium will determine what caliber of LED lighting is needed.

It might seem really obvious but it’s not simply down to covering a larger space. A large aquarium will be wider, deeper and you’ll need an LED whose light can penetrate the entire tank. It is easy to find sub-par lights with poor coverage, that might be suitable for a small or shallow tank. There are many types of saltwater aquarium, such as Fish only, Fish only tanks with Live Rock (sometimes abbreviated to FOWLR) etc.

2. Types of aquarium plants

Another crucial factor is the aquarium flora that you’re keeping. A mature tank with fully developed plants will require a varying level of light intensity than say, a newly planted tank. A newly planted tank will be very much in the growing phase – and your coral or tropical plants will need strong light to develop.

There are many types of aquarium plants, and each of them have different light requirements. That means there will be unique LED setups for each version, which is why it’s important to consider this when you’re planting your tank. If you don’t you’ll end up with plants that require different types of light and that’s a logistical nightmare.

3. Varying light spectrum and LED brightness

Look at the image to the left, there are so many LED spectrum’s and intensities for an aquarium. Some lights are programmable for different limits, but cost will be a factor. The vast majority have one setting and it’s important to find the right one.

The varying levels of brightness and spectrum’s of the lights are unique to the fish and fauna that you have. That’s why we’re fans of having tanks that contain the fish and plants from the same area. That is both satisfying to create, and the best environment for the fish.

4. Costs & Characteristics

A final factor that you need to be aware of is the cost. There’s something for everyone in the range of LED systems and don’t be fooled by price points. Like most consumer products, brands carry a heavy price tag but that doesn’t always equal performance. Some LED lights come will a lot of extras that aren’t worth the budget in the long run. You’ll be able to find some very suitable systems at a price that won’t break the bank.

Because there’s such a diverse range, from seasoned coral expert to beginner, there is something for everyone – so don’t worry, there will be a way to find a product to fit your budget.

Comparing Value: Best LED Aquarium Lighting

We’ve compiled this list of the most popular led aquarium lighting systems for 2020. Each one offers great value and have it’s own positives and negatives. Consider the above factors when looking at each product and weigh up value vs benefit.

What makes LED aquarium lighting different?

LEDs are essentially just diodes that when connected to a source of energy, electrons within them convert into photons that emit light radiation. LED aquarium lights are small Light Emitting Diodes, that when put together on mass, produce a powerful light. These lights are easy to design in an array of colors and intensity settings.

The best aquarium LED lights often come with various programmable settings; such as sunrises and sunsets, bright growth phase lights, and even moonlight settings for fish that enjoy them.

LEDs also have various colors and spectrum’s, which means exceptional growth for plants, corals and even live rock.

What are the benefits of LED aquarium lighting?

benefits of aquarium LED lighting

The benefits of LED lights for aquariums is well documented. Let’s quickly cover the main reasons why this type of lighting is essential for your fish tank:

  • LEDs produce about 8 times more light per watt of energy than standard bulbs. Most companies list lifetime at 30k-50k hours, that’s 7 years minimum even if you run it 12 hours a day.  You certainly save on the electrical bills here!
  • Not only energy efficient, but have a low base price initially too.
  • LED lighting generates less heat than other aquarium lighting. That means less temperature changes throughout the day. Unlike a heater, you can’t let the aquarium cool if the lights give off radiant heat as well.
  • The LED lights are excellent for fish and coral and plant life. They deliver 8,000K to 10,000K of lighting, which allows for optimal growth – providing UV rays without the damage.
  • Small, compact and water resistant make them perfect for use as a fish tank light.
  • LEDs go individually, meaning you won’t have to replace the whole unit if the lights go out!
  • The good quality LED lights can produce light of different intensities and colors, which in turn produces an optimum ambiance for the aquatic growth in your aquarium, whatever be its kind and stage of growth.
  • No toxic waste is created when using LEDs: they are much safer than metal halide and T5 fluorescent lights. With a lack of metal filaments and noxious gasses, these are environmentally friendly.
  • They won’t shatter like tubes
  • Dimmable – AquariumLEDs have great dimming capacity, whereas fluorescent tubes are expensive to dim and do so poorly as well
  • Quality of light – less flickering
  • Finally, the LED lighting systems are known as visual effects for an aquarium. They shimmer of plants, coral and fish, bringing out vibrant colors you didn’t even know were there.

As of right now, we cannot really think of any major downside to using LEDs over standard tubing. Aside from the initial cost difference, which really is irrelevant because the cost of savings offsets that. Let’s get down to the in-depth reviews and select you the best aquarium LED lights!

We also have specific articles on the best LED lights for reef tanks and the best LED lights for tropical tanks too.

Wrapping up: LED Fish tank Lights FAQs

Are Aquarium LEDs best suited for plants in a growth phase?

Absolutely. If you’re trying to grow plants quickly then you’ll want to get hooked up with a LED lighting system and also consider a CO2 generator.

The light spectrum emitted by the LEDs mimics natural sunlight, without causing excess algae.

How should I set them up?

Depending on the size and shape of the tank, you can either use a hanging LED light system, or the standard clip on systems. We’ve profiled both above. We tend to use two led strips or one large one in the middle.

Some of them have a bigger 120 degree profile and can adequately cover the whole area. Take a look at some aquascaping examples to see how they’ve lit up some areas of the tank over others.

How does LED light spectrum affect growth of plants?

LED aquarium lights are designed to help plants grow. They mimic the sunlight and promote photosynthesis needed for plant growth. The spectrum of light is both visible and non-visible.

They are much better than light tubing because of the broader light spectrum and the colors they emit. Furthermore, with programmable LEDs – you can construct the natural changing of light within a day.

Will my aquarium plants grow under LED lights?


My aquarium plants aren’t doing well, what’s wrong?

The most common issue here is that the aquarium isn’t aged, i.e. good bacteria hasn’t built up in the filter and you introduce plants too soon. Also, you may have purchased the wrong plants; check out requirements at the aquatic plant database.

When should I turn off an aquarium LED light?

That totally depends on what fish and what plants you have in the tank. This is why we’re fans of using fish and plants from the same regions. Fish from Europe may get 8 hours of medium light a day, if you pair them with afircan fish that have strong sunlight for 12 hours, then you will end up with sick fish.

Always ensure that it is off at night! Use a timer.

How high should I hang LED aquarium lights?

There’s no requirement here. We usually hang them about 3-4 inches above the surface of the water. This is the same for both clip on and hanging types.

Are LEDs really that much better than fluorescent tubes?

Yes they are. We’ve summarized the benefits of them, above in the What are the benefits of LED aquarium lighting section. Essentially, they provide a better light spectrum for plant growth, longer lasting life, less energy consumption, are programmable, bring out the colors in fish and live rock better and are mercury free.
