5 Best Aquarium Lights For Your Home Aquarium

Adding an aquarium to your home is a delightful way to enhance its ambience, but it’s essential to provide proper lighting to ensure the health and happiness of the aquatic creatures living inside. However, selecting the ideal aquarium light can be an overwhelming task, as there are numerous options to choose from in the market.

In this article, we’ll present a detailed guide on the best aquarium lights, covering various types, factors to consider, and suggestions for different aquarium sizes.

Types of Aquarium Lights

There are four main types of aquarium lights available in the market:

Fluorescent Lights

Fluorescent lights are the most commonly used lights in aquariums, mainly because they are affordable and easy to find. They come in a range of sizes and colours, making them suitable for different types of aquariums. However, they are not very energy-efficient and need to be replaced frequently.

LED Lights

LED lights are becoming increasingly popular due to their energy efficiency and longevity. They produce less heat, making them suitable for delicate aquatic life such as corals.

LED lights are available in a variety of colours and can be programmed to simulate natural lighting, making them ideal for planted aquariums.

Metal Halide Lights

Metal Halide lights are the most powerful and brightest lights available in the market, making them suitable for large aquariums with deep water. They are also ideal for aquariums with corals as they simulate natural sunlight, promoting coral growth.

However, they are expensive and produce a lot of heat, which can be harmful to delicate aquatic life.

Incandescent Lights

Incandescent lights are the least energy-efficient and the least popular among the four types. They produce a lot of heat and emit a yellowish light that can distort the colours of the aquatic life within the aquarium.

Which type of light is the best for an aquarium?

The best type of aquarium lights will be LED lights. They are bright, energy-efficient and last for a long time. That’s the reason why we see a lot of new fish aquarium light products to be LED lights.

We foresee that LED lights will dominate the market for a very long time and it makes every sense to use LED lights for your aquarium tank.

Factors to Consider

When it comes to selecting the optimal aquarium light, there are several important factors that need to be taken into consideration. By carefully evaluating these factors, you can ensure that you make an informed decision and provide the best lighting conditions for your aquatic environment. Let’s explore these factors in detail.

Type of Aquarium

The type of aquarium you have plays a crucial role in determining the kind of lighting it requires. Different types of aquariums, such as planted aquariums and coral reef aquariums, have specific lighting needs. Planted aquariums thrive under lights that provide a specific spectrum, promoting healthy plant growth. On the other hand, coral reef aquariums require lights that closely replicate natural sunlight to support the growth and vitality of the corals.

Size of Aquarium

The size of your aquarium is another essential factor to consider. The dimensions of the tank directly impact the type and number of lights needed. A smaller aquarium may only require a single light source to provide adequate illumination, while larger aquariums necessitate multiple lights to achieve an even distribution of light throughout the tank. Properly lighting the entire tank ensures that all areas receive the necessary light for the well-being of your aquatic life.

Type of Aquatic Life

The specific type of aquatic life you have in your aquarium also influences the lighting requirements. Different organisms have varying light needs. For instance, corals typically demand high-intensity lighting to thrive and display their vibrant colours. On the other hand, fish and plants may have different preferences when it comes to the spectrum and intensity of light. It’s important to choose a light that caters to the specific needs of the organisms in your aquarium to promote their health and overall well-being.


Establishing a budget is an essential step before embarking on your search for the ideal aquarium light. The cost of lights can vary significantly depending on their type and brand. By determining a budget, you can narrow down your options and focus on lights that are within your price range. However, it’s crucial to strike a balance between your budget and the quality of the light. Opting for a reliable and durable light may be a wise long-term investment, as it can save you from frequent replacements or potential issues down the line.

Energy Efficiency

Considering the energy efficiency of the aquarium light is not only environmentally responsible but also helps save on electricity bills. LED lights are widely regarded as the most energy-efficient option available for aquariums. They consume less power while providing ample light output. Following LED lights, fluorescent lights are considered relatively energy-efficient. By choosing an energy-efficient light, you can reduce your environmental footprint and enjoy long-term cost savings.

Aquarium Lights for Different Aquarium Sizes

Different aquarium sizes will need different aquarium lights. Let’s look at the 3 main sizes and what will be the recommended products.

Small Aquariums (10-20 gallons)

For small aquariums, LED lights are the best option as they are energy-efficient and provide ample lighting. We recommend the Nicrew ClassicLED Aquarium Light as it is affordable, provides a good spectrum of light, and has adjustable brackets to fit different aquarium sizes.

Medium-Sized Aquariums (20-50 gallons)

For medium-sized aquariums, we recommend the Finnex Planted+ 24/7 Aquarium LED Light. This light has a customizable 24/7 mode, allowing for a sunrise and sunset effect, as well as a variety of color spectrums to promote plant growth.

Large Aquariums (50+ gallons)

For large aquariums, metal halide lights are the best option as they provide the necessary intensity of light for deep water and coral growth. We recommend the CURRENT USA Satellite Freshwater LED. This model could cater for tanks as wide as 60 inches.

Choosing the best aquarium light can be a daunting task, but it is an important decision for the health and well-being of aquatic life within the aquarium. Consider the type of aquarium, size, type of aquatic life, budget, and energy efficiency when choosing the best aquarium light.

LED lights are the most energy-efficient and versatile, while metal halide lights are the best for large aquariums with corals.
