Buying Guide: How to Choose the Best Aquarium Light?

If you’ve ever asked yourself how to choose the best aquarium light, you’re not alone. More and more people are setting up fish tanks in their homes, and that number is only going to grow.

Before you get started with finding the best light for your tank though, there are some things you need to know about fish tanks.

Aquarium lights don’t just help fish live better lives; they also help make your home look nicer. Not only will a brighter light make your fish happy, but it will also give off an inviting atmosphere in your house. With this guide, choosing the best aquarium light has never been easier!

What is the Best Aquarium Light?

Like plants, fish need a certain spectrum of light to thrive. The best aquarium light will provide the proper balance of UV and visible light that your fish need to stay healthy. If you’ve been struggling with finding the right lighting for your tank, it might be time to invest in a new light fixture. You can find fixtures at your local pet store, as well as online at sites like Amazon.

The next big question is whether or not you want a fluorescent or LED light. It all depends on what you’re looking for in a light. Fluorescent lights are cheaper and easier to find but they don’t offer as much color as LEDs do. LEDs also produce more heat than fluorescents which might affect how comfortable your fish feel in their environment.

The importance of light in fish tanks

Fish tanks are more than just decorations for your home. They’re actually a living ecosystem of their own. And, like any other ecosystem, it needs light to survive.

Different fish require different amounts of light in order to thrive. Some fish need more than others. For example, some tanks only need natural light that shines into them from the sides or top. These tanks don’t need any additional lights because they get enough sunlight on their own. On the other hand, other tanks might need a lot more light in order to sustain life and give off a healthy appearance for your fish and decorations.

Choosing the best aquarium light is important because you can customize it to meet your fish tank’s needs and keep your fish happy and healthy!

Types of Lights

There are two types of light in the world of aquarium lighting: fluorescent and incandescent. They both have their own drawbacks, but there are some pros to each type.

Fluorescent lights are popular because they’re energy-efficient and come in a wide range of color temperatures. However, they also need to be replaced more often than incandescent lights.

Incandescent lights are generally cheaper than fluorescent lights. They can also emit more light than fluorescent lights, which is perfect for larger tanks with lower water levels. But the downside is that they don’t offer much light at all when submerged underwater.

Different Types of Aquariums

A simple way to choose the best aquarium light for your tank is to consider the type of aquarium you have.

  • Fish tanks are one of the most common types of aquariums. It’s easy enough to find a light that will work for this type of aquarium, although you might want to choose a higher wattage light because fish tanks typically have more water in them.
  • Nano fish tanks are another popular option for pet owners who can’t afford a large tank or don’t have room for one. These small tanks allow you to keep just one or two fish at a time, but they also come with their own set of challenges when it comes to lighting. Nano fish tanks are typically lit with LED lights, which are usually low wattage and provide less light than other lights.
  • Freshwater fish tanks like these often need high-wattage lights because they’re full of algae and different plants that need more light in order to thrive.

How to Choose the Best Aquarium Light for Your Tank

Aquarium lights are usually used to help provide fish with the natural progression of day and night. Most aquarium fish come from different parts of the world, so they need a light cycle that mimics their natural habitat.

The most important thing you should consider when choosing the best aquarium light is the tank size. As you increase your tank size, you’ll need to adjust your lighting needs accordingly. A larger tank will need more powerful light than a smaller one, so keep this in mind when deciding which type of light to buy for your tank.

It’s also important to think about how close your aquarium will be set up to a window or bright outdoor space where it can get plenty of natural sunlight. If there is a window nearby, make sure it isn’t too sunny or cloudy outside that it disrupts your aquarium’s natural lighting cycle.

Another factor that should influence which type of light you purchase is the color spectrum. The color spectrum plays an important role in how much energy fish use and how healthy their scales stay. Generally, fishes from warmer waters require tanks with blue lights while fishes from cooler waters require tanks with red lights.


Picking the best light for your tank can seem daunting, but it doesn’t have to be! We’ve compiled a list of the top 10 best aquarium lights to help you make an informed decision.

If you’ve never owned an aquarium, or haven’t updated your lights in a while, this list is for you. Make sure to keep this article in mind while you shop to ensure you find the best light for your tank and for your budget.
