Best Aquarium Lights for a Balanced Fish Tank

Starting your fishkeeping adventure means, among others, getting the parts and supplies that are essential for keeping your fish happy and safe. When you try to create a balanced environment inside your fish tank, aquarium lights are crucial and a mandatory addition to the shopping list. Depending on your aquarium’s size and the type of fish and plants you plan to have, you need to find the fish tank lights that meet all your particular requirements.

Your fish tank light will do more than merely make your aquatic ensemble look more attractive and make it easier for you to enjoy every small detail that you have carefully planned. Light is essential in creating an environment as close to the original as possible. That way, your fish won’t feel any discomfort, and you will be able to handle the aquarium’s maintenance much easier.

Aquarium lights are crucial if you want a planted aquarium, as they will need the right amount of light to grow and stay healthy. And keeping your plants healthy means more oxygen for your little finny friends. On the other hand, a good aquarium lamp will help you keep a close eye on the water quality and immediately notice any issues that may come along. Everything inside the aquarium, from fish and plants to corals and healthy bacteria, needs light. So, finding the right fish tank lights is a crucial step.

Below, we will go over the best aquarium lights you can find on the market and then take a look at the features you want to keep an eye on before making a decision. You will find that many aspects are involved, but the time you spend setting up the ideal fish tank will definitely be worth it.

Unlike others on this list, the aquarium LED strip from S Smiful is waterproof, and you can completely submerge it into the water. But you have to make sure to keep the power adapter, the switch, and the remote out of the water.

While definitely a cool option, it’s not the best if you plan to add live plants. For aquarium plants, lights should be placed on top. This strip can also be mounted on top of the fish tank, but it doesn’t really make sense to buy a submersible version and not take advantage of all its features.

It works well, comes with a decent price tag, and since you can place it anywhere you want inside the tank, it can be fun to use. Still, if you have a planted tank, you must use it at the top, so you won’t get to enjoy all the cool features. But overall, it’s a great option and worth buying.

#5 – Koval Aquarium Lighting 

The Koval LED aquarium light is another great option for creating a comfortable environment for your fish and your live plants. These are full-spectrum LEDs and quite a top-quality product, so you can count on them to light your aquarium for at least 50000 hours.

Still, the LED aquarium lights work well, and for the price, they are worth purchasing.

Elements to Consider when Choosing the Best Aquarium LED Lighting

Many products are available on the market, but that doesn’t mean choosing the best aquarium lighting fixture is always easy. If you’re not sure which one would fit your fish tank best, the easiest way to decide is by keeping a few crucial aspects in mind.

The type of fish tank you have

There are actually a few different elements that you must consider at this point. Your tank’s size is one of them; depending on its dimensions, you can decide how many lights you need and how bright they must be. A narrow strip may not be enough if you have a wide and deep aquarium.

Apart from the size, it’s also important what you plan to place inside the tank. Different fish and plants require particular lighting conditions, so make sure to do a bit of research before starting your shopping list. If you want a planted aquarium, lighting is essential, and you must make sure it will be bright enough for the live plants to grow but not too bright, so you can avoid an algae outburst.

There are even different lighting requirements between saltwater and freshwater aquariums, but we’ll address those a bit later.

Light modes

Using different light modes or just one is more connected to your preferences, rather than your fish’. Think about what you would like to look at every day, a single setup or a changing environment that can even include storms. If you are into special features, look for cool fish tank lights that you can adjust any way you want.

Your fish may not be that interested in your stormy setting, but if you set the lights to mimic the natural light cycle, they will probably feel more comfortable. Any feature that brings the aquarium closer to the natural environment is useful.

Waterproof or water-resistant

These may sound similar, but, in fact, they are quite different. Waterproof aquarium lights are those that you can submerge and place anywhere you want inside the tank. Many products can be used both underwater and above the water surface, as you saw on our list.

Submersible fish tank lights need to be waterproof, for obvious reasons, while those you place on top of the aquarium only have to be water-resistant. Splashes can happen, and humidity can be dangerous if you don’t choose the right product.

Types of Aquarium Lights

The easiest way to categorize the fish tank lights available on the market is by dividing them into two major types, freshwater fish tank lighting, and saltwater tank light.

Freshwater aquarium lights

Freshwater aquariums host fish that come from environments where the sun is usually abundant, like rivers or lakes. So, you must consider that and opt for freshwater aquarium lighting that can mimic that level of light as well as possible.

At the same time, your freshwater fish will also need a few darker hiding places, just like they would have in the natural environment. That means you don’t want lights so bright that they cover every little segment of the fish tank. Plants will also help create these hide-outs for your finny friends, so they can have a bit of privacy and feel safe.

There are a few different choices for freshwater aquarium light; we have chosen LEDs for our list because they are the most versatile, but there are a few others you can look into:

  • Incandescent aquarium light can be an option, though it’s not exactly a popular one. Incandescent aquarium light bulbs do create a softer and more pleasant light, so you may be tempted to use them to create a more natural-looking environment. But they also produce a lot of heat, which is not right for aquariums.
  • Standard fluorescent fish tank lights are a cheap and easy-to-use option that many people choose. They come in many colors and can be placed on different types of fixtures. The disadvantage is an aquarium fluorescent bulb is quite large, so it won’t fit in a standard fixture. On the other hand, if you create personalized aquarium fluorescent light fixtures, they will be far from subtle.
  • Compact fluorescent aquarium light is a better option because the bulbs are smaller, and the light is more intense. They still eliminate significant heat, so if you decide to use compact fluorescent lighting for fish tanks, you will have to find a way to counterbalance that heat.
  • T-5 HO bulbs are another variant of fluorescent aquarium light, but it’s still not a very popular one. These bulbs don’t create as much heat as the others, but the brightness is also low, so they are only suitable for shallow aquariums.
  • VHO, or Very High Output bulbs, do a great job lighting up your fish tank. Unfortunately, they also create a lot of heat, so you need to use a strong fan or an aquarium chiller to keep things under control.
  • Metal Halide lights are also quite powerful, and people sometimes use them for large and deep tanks. But, again, you will have to deal with the extra heat.
  • LED aquarium lights (or light-emitting diodes) are the best option for many reasons. They are small enough to be easily hidden in a modern-looking shell, strong enough to penetrate even a deeper aquarium. They don’t eliminate heat, and they are incredibly energy-efficient.

Saltwater aquarium lights

Saltwater fish tank lighting is essential for the healthy development of your fish but also those beautiful corals you may want to add to your underwater environment. They need bright light to thrive. Saltwater tank lights must meet the needs of various inhabitants: fish, invertebrates, corals, and even live rock.

Apart from the intensity of the light, it’s also crucial to maintain a steady temperature in the tank. Saltwater environments are quite sensitive to change and must be kept as balanced as possible, so you need light fixtures that don’t generate a lot or any heat.

While Metal Halide and fluorescent fish tank lights are sometimes used in saltwater tanks, their usage is limited for the reasons we mentioned above. LED saltwater aquarium lighting remains the best option, as it helps you create and maintain a balanced environment for all the tank’s inhabitants.

Also read – Is Aquarium Salt Necessary in Freshwater Tanks?

If you’re wondering what to look for when buy LED lights for a saltwater aquarium, the requirements are pretty much the same as for freshwater tanks. There is, however, one aspect you should keep in mind; look for LED lights for saltwater tanks that offer spectrum stability. It’s essential that the light maintains both color and brightness over time to keep the water parameters stable.

Do I Really Need Fish Tank Lights?

The answer to this question depends on what you intend to place inside the tank. If it’s a fish-only tank, you don’t necessarily need additional aquarium lights. Your fish don’t really need high levels of light. In fact, you may notice that they sometimes look for a darker retreat to relax a bit. Still, if the natural light in the part of the room where you keep the aquarium isn’t that great, adding lights can help.

But if you want live plants, light is essential, and you must make sure it’s strong enough to meet the needs of your plants, according to their height and type. Corals and invertebrates also need life, as mentioned above. So, if you want to set up a reef tank, saltwater fish tank lighting is a must-have.

Aquarium lights may not be mandatory if you have a nano tank without any plants. But considering how affordable fish tank lights are and the cool features they offer, why not use them? LED aquarium lights will create a fantastic effect in your tank, will last for a long time, and won’t add that much to your electric bill, so they are worth buying even if your aquarium doesn’t really need them.

The Algae Dilemma

While fish tank lights can look great and turn your underwater environment into an eye-catcher, they also come with particular concerns. You may worry that too much light can cause an algae infestation; it’s a common preoccupation, especially among beginners. One of the most frequent questions is ‘what kind of lights cause algae in a fish tank?’.

The fact is you cannot blame the algae problem in your aquarium on light alone. There are usually more factors involved. A small amount of algae isn’t necessarily a problem, as it’s a natural element; it’s when it gains too much ground that the issues begin. But that doesn’t always happen because the light is too bright.

To make sure algae won’t become an issue, you need to keep the tank as clean as possible. That means conducting water changes regularly and monitoring the water quality. You may be dealing with too much waste. As for the light, it’s not only the brightness that matters but also how exposed the fish tank is during the 24 hours cycle. So, if you’re wondering, ‘how long should I leave the lights on my aquarium to prevent algae?’ the answer usually is 8 to 10 hours.

So, it’s not all about finding the best aquarium light to prevent algae; other factors are involved, too. For example, choosing the right live plants can help keep algae under control. Fast-growing plants will do their part and compete with algae for the same nutrients, thus preventing them from getting out of control.

The solution also depends on the type of algae you are dealing with. For instance, if you have rust-colored algae in the fish tank, it means you need to check the water quality and improve it by using a nitrate-removal.

FAQs on Aquarium Lights

How to tell what lights are needed for plants according to the size of the fish tank?

The size and shape of the aquarium play essential roles in choosing the best aquarium lights. As a general rule of thumb, if you have a fish-only tank, you need one or two watts per gallon, and if you want live plants, you need three to five watts per gallon. As for reef tanks, they require four to eight watts per gallon to keep the corals thriving.

How long to leave aquarium lights on a planted tank?

The usual rule for planted tanks is not to leave the aquarium lights on more than eight hours a day. For a new aquarium set-up that includes plants, you need to keep the lights on for at least six hours every day. Then, as your plants begin to grow, you can slowly increase the period. If you leave the lights on for too long from the start, algae may become a problem, as they may grow faster than your plants.

How to hang LED aquarium lights?

If your aquarium lighting fixture isn’t set in a hood or mounted on the tank with brackets, there are other ways to fix them in place. You can hang them, either from the ceiling or from the wall. You can use cable kits for the first option, but you will have to drill holes in your ceiling and be extremely careful centering the lights in the right place.

The easier way to hang LED aquarium lights is from the wall. You can use brackets that are usually used for heavy shelves; they come in different versions, some of which look quite nice. Since they are coated, the humidity from the fish tank won’t be an issue. You also need a few strong toggle bolts and a couple of cables, and you will be done in no time.

Where can I buy aquarium lights?

You can buy fish tank lights from your usual pet suppliers if you want to go to the store in person. The more comfortable alternative is to order it online, from Amazon or Petco; you will probably have more options to choose from this way. Our list of best aquarium lights on the market also mentions the prices on Amazon to help you plan your shopping list.

How to dim aquarium bright LED lights?

Many fish tank lights come with a dimmer to help you set the right level for your fish and plants. Those that don’t can also be customized quite easily, using a PWM dimmer controller switch. Take a look at the video below to see exactly how to install the dimmer:

Why do my fish stay at the bottom of the tank when the lights are on?

You shouldn’t always worry if you notice your fish tend to stay at the bottom of the tank when the lights are on. Just like us, they need their moments of relaxation, when they will find a darker place to rest a bit. That place can be hidden in the aquarium plants or at the bottom.

Still, if you notice that your usually vivacious fish start spending too much time at the bottom, you should look into it. They could be sick or simply bothered by the too intense light. It’s also important not to leave the lights on for longer than necessary because it can get the fish to swim around until they are exhausted. If they cannot rest well and enough, they can get sick easier.


Aquarium lights are another essential element you need to consider for your fishkeeping experience. They may not be mandatory for all tanks, but they sure enhance the beauty of your fish, and your aquascaping efforts will be more obvious. On the other hand, for certain types of underwater environments, fish tank lights are necessary.

And the fact is choosing the best aquarium lights isn’t that difficult, especially if you consider the elements we have talked about. As we have shown, LED aquarium lighting is the best option, as it checks all the boxes, and it helps you reduce costs in the long run. With so many variants available, you will definitely find the one to help you make your beloved aquarium stand out.
