​Benefits of LED Lighting for Reef Tanks

Due to the nature of the tank elements and water chemistry, reef tanks are quite different to typical freshwater tanks.

Furthermore, you can’t expect optimum growth of your aquatic plants and coral in your reef tank if you are planning on using an LED lighting system which is designed for freshwater tanks.

Why is that?

It’s because coral demands red and white light for faster growth, whereas freshwater plants only require blue light.

So, your reef tank will need a different lighting system.

Okay, but why should you consider installing an LED lighting system rather than traditional tungsten bulbs or fluorescent tubes?

Because of energy efficiency and color versatility.

You should know that LED lights are far more energy efficient and have a much longer life expectancy.

For example, fluorescent bulbs tend to have 7,000 to 15,000 hours of lifespan. On the other hand, LED bulbs have 50,000 to 100,000 hours of lifespan.

In addition, LED bulbs will consume much less energy compared to other types of light.

Perhaps I should talk in more detail about the benefits of LED lights. So, check out these crucial decision-making points:

Brighten Up the Aquarium

Why are you using lights in your aquarium? To brighten up the aquatic environment, right? So, the main and the most important function of lights is to brighten things up.

And when it comes to brightness, LED bulbs outshine any other kind of light. In addition, LED lighting systems can deliver different kinds of visual effects as well as creating a really bright environment.

And that’s not all.

You will probably find different pre-set or programmable modes with many lights on the market right now.

So, it’s safe to say that LED lighting systems are the most advanced lighting systems, technologically speaking, with the brightest lights.

Safe to Use

Having an electric system near an aquarium can be a worry. Nobody wants to electrocute their beloved fish.

A lot of LED lighting systems offer water resistance so that you can have them near your aquarium, eliminating the need to worry.

Even LED lights without a water resistance rating are much safer than older metal halide and fluorescent bulbs.

For example, metal halide bulbs contain tungsten which can burst under many conditions, and fluorescent bulbs contain hazardous gasses. These bulbs can burst, causing the leakage of harmful elements.

With LED bulbs, you won’t need to worry about such unwanted situations.

Generate Less Heat

Most members of your aquarium (both fish and plants) are temperature sensitive. They prefer to live in an optimum temperature condition.

Many of you will use aquarium heaters for this reason, but lights will also dissipate heat with prolonged usage.

Therefore, the water temperature will increase gradually which can bring about an unhappy situation.

Due to the nature of LED bulbs, they tend to produce much less heat. In addition, most good brands include various heat dissipating mechanisms in order to minimize the low heat produced by the lights.

Two of the most common heat dissipating mechanisms include:

– Fan

– Heat sink

Generally, you can expect less issues with excess heat coming from your LED lights.

Better Growth of Plants and Marine Animals

Light is one of the basic needs of life. This is especially true for aquatic plants and coral.

Plants are dependent on light for the process of photosynthesis and coral requires optimum light for a healthier growth rate.

Typically, plants require 6500K of white light. Almost every single LED light on the market surpasses that level. Some lights even offer 10,000K or 12,000K of white light.

More Compact

We all want to have a clutter-free, minimal looking aquarium, at least on the outer peripherals.

In this regard, one of our enemies is wires randomly hanging out of the tank.

The good thing about LED lights is that most systems are compact.

Furthermore, these bulbs are much easier to install and have modern installation mechanisms.

Features of the Best LED Lighting for Reef Tanks

Suppose you are in the market to buy the best LED lighting for reef tanks. What should you look for?

Wattage? Color availability? Light intensity? Or something else?

The correct answer is all of these and more!

Many of us choose a lighting system that simply looks great. This is a marketing technique which is used to make you fall for looks rather than functionality.

So, let’s not fall for such cheap marketing tricks. If you want to own the best LED lights for a reef tank, you should look for these essential features:

Power Consumption

As the lights will need to operate for at least 14 hours a day, you should look for an energy efficient option. Yes, LED lights are generally energy efficient, but there are some models which are more efficient than others.

However, there is a strong relationship between power consumption and light intensity. If a light consumes more power, it should offer more light.

You need to find a balance.

However, there are certain models which offer bright shiny light despite their low wattage.

Installation Process

Not everyone is good with tools and if you don’t have advanced level tools in your house, you should check for the installation process of a lighting system.

Some brands offer a simple installation system, such as using suction cups and simply powering up the system, while some models are just too complex to install.

Make that you buy a simple one.

Ease of Use

How hard can using an LED light be? Don’t push your luck as some LED lighting systems can be very difficult to operate.

This is especially true if the system control has 30+ buttons with programmability. You will need to deal with various modes and settings too much.

Yet again, we are looking at a trade-off. If a lighting system is loaded with features, it will certainly have a complicated usage procedure.

But it shouldn’t be so complicated that you can’t operate it properly. If you are a non-tech-minded person, you should just stick to simpler systems.

Lighting Capabilities

Perhaps this is the most crucial feature of them all. You should never compromise with light capability.

Reef tanks demand more light compared to planted or freshwater tanks.

What is the ideal LED watts per gallon for reef tanks?

It should be somewhere between 4 and 8 watts.

So make sure that your preferred lighting system offers that.

There are a few things which you should check first:

​​> How many colors does the system offer?> What are the wavelengths of these colors?> What is the light dispersion angle (a wider angle ensures wider light dispersion)?> How many channels does the system have?> How many individual LED bulbs does the system have?

These are some of the basic questions which you should ask about a specific model.


Aquascaping is not a short-term hobby. It’s not like you are aquascaping one day, and the process ends after 2-3 months.

It requires long-term commitment.

As with your own personal commitment, your LED lighting setup should also demonstrate a long-term commitment.

Typically, an LED bulb lasts for approximately 50,000 hours. I would say that this is a good figure. However, you should aim for those with the longest life.

Some brands promise lights with a 100,000-hour life or even longer! However, you should still enquire about the warranty period.


I think the winners are pretty clear today.

The number one spot for the best LED lighting for reef tanks goes to Current USA OrbitMarine Aquarium LED Light. It’s an obvious choice as it offers the finest quality lighting.

Next, second place goes to Kessil AP700 LED Aquarium Light in the premium category.

And finally, third place goes to VIPARSPECTRA Timer Control Dimmable 165W 300WLED Aquarium Light for being the perfect budget-friendly option.
