Buyers’ Guide 

What are some things to look for when buying LED aquarium lights? 

Here are some aspects of LED Aquarium Lights you should think about before going out to purchase one: 

  • Build Quality 

The quality and durability of your LED lights matter a lot. There’s no point investing a large sum of money in a product that’s going to break down in a few months. It’s a good idea to look into reviews of people who’ve had the product for a long time in order to ensure it will be able to give good performance consistently for a long time. 

When you’re in the shop and looking at LED lights, start by observing its outer layer and making sure it’s tough and water-resistant and that it will be able to protect the lights inside from any splashing. 

  • Customizability 

LED lights give you the liberty to customize, control and program them in limitless ways so it’s a good idea to get a lighting fixture that has features that will let you use them to their fullest potential. 

There’s no telling what kind of changes you make to your aquarium down the line. For example, there may come a time when you introduce fish to your aquarium which may require a different intensity of light. In that case, having a lighting fixture that is able to control the intensity of light in it will be very convenient for you as you won’t have to go out and purchase different lights for your new fish. 

  • Aquarium Size and Type 

Obviously, the size of your aquarium matters and you need to get lighting that will be able to light up every corner of your aquarium adequately. Be sure to get lighting that will be able to effectively penetrate the water all the way to the bottom of your fish tank.

These days, different LED lighting setups are specifically catered to different types of aquariums. You should definitely decide on what type of aquarium you intend on having in your home before you go out and buy lighting for it. Some different types of aquariums are freshwater tanks, saltwater tanks, brackish tanks and coral reef tanks.

Why are LEDs the preferred type of lighting for aquariums? 

LEDs have become the number one option for every kind of fishkeeper. This is because they are pretty much better from their competitors in every way. 

  • They last longer. 
  • They use less energy. 
  • They are very customizable. 
  • They don’t produce heat. 
  • They are smaller in size. 

Is there an instance where I would want some other type of lighting for my aquarium?

Yes. There do exist some unique cases in which you may want to opt for other forms of lighting. 

For example, if you have a fish tank that’s deeper than 24 inches or an aquarium that’s generally very large, you may want to invest in metal halide lights to light it up as they have much higher penetration power in water than LEDs. LED lighting may not be able to get to every nook-and-cranny of these larger aquariums the way metal halide lights can. However, it has to be noted that metal halide lights create a lot of heat. If you do intend on getting metal halide lights for your aquarium, you’ll have to invest in a chiller as well as these lights tend to make the tank water hot which could prove fatal for your fish if not addressed properly. 

How do I Install LED lights onto my aquarium?

Setting up aquarium lights is not usually a very difficult process since most companies take great pride in boasting that their lights are very easy to set up. That’s why many LED lights feature intuitive designs that help you set them up in no time. 

Since there’s such a wide variety of LED lights out there, the individual process of installing them onto your aquarium may differ slightly from product to product. 

Most come with brackets, hinges or fittings that can attach to the walls or lid of your aquarium. Others can be hung on top of your aquarium. 

For most standard-level LED lights, they are good to go as soon as you mount them onto your aquarium, all you have to do is turn them on. 

For other more expensive models with more features, you may have to set up and program them digitally. This may include setting up a timer for them, setting their mode and any other small features which you may want to tinker with.

When should I turn off my LED aquarium lights?

You should never leave your LED aquarium lights on indefinitely. It’s a good idea to turn them off at night as you’re going to sleep.

Frequently Asked Questions (FAQs)

Do I really need LED aquarium lights?

Yes. Investing in good LED aquarium lighting is a very good idea because not only do you need decent lighting to show off the brilliant colors of your fish and aquarium plants, you also need it to simulate a natural environment for your fish and also for proper nourishment of your living aquarium plants.

Can’t I just use regular LED strips to light my aquarium rather than investing in expensive lighting?

Yes. You can definitely use regular LED strips to light your aquarium but you can imagine how arduous the process would be. You’ll have to adhere them to your aquarium and make many adjustments in order to ensure that every corner of your aquarium is lit properly. 

Not only that, you won’t get any customization options with LED strips as you would in a proper LED lighting fixture such as brightness control, pre-set modes, sunset/sunrise simulation options, timers, color changes, etc. 

How long does LED lighting normally last?

LED lighting has a very long lifespan. Normally LED lights can last from anywhere between 50,000 to 100,000 hours. 

Are LED lights submersible?

No. In most cases, LED lights are not meant to be submerged underwater. Most aquarium LED lighting available in the market is meant to be hung above the aquarium away from the water.

That being said, submersible LED lighting does exist. There do exist brands that have made a name for themselves by selling LED lights that can be completely placed underwater. As you can probably imagine, these lights have an aesthetic that’s all their own.

We strongly advise you don’t submerge any of your LED lights unless they have explicitly stated that they are submersible.

Can I use LED lights to grow aquarium plants?

Yes. LED lights can definitely be used as a grow light for aquarium plants. There are even LED lights available that are specifically made for the growth of live aquarium plants.

Does the color of LED lights affect aquatic life in any way?

Yes. It’s been scientifically proven that fish in aquarium settings respond the best to a combination of cool white light and blue actinic light. This combination is not only pleasing for humans to look at, but it’s also very relaxing for fish. 

If you have a coral reef tank, this combination of light is very beneficial for them as well as it has been proven to promote coral growth. 

As for live aquarium plants, the colors of blue and violet in lighting have been proven to be the most beneficial for them.

Do blue LED lights cause algae?

Yes, blue lighting can cause excessive algae and low kelvin lighting that’s peaking in the red area can cause algae in marine environments. This is usually caused because bulbs tend to degrade over time which causes the color temperature of the lights to change slightly. 

You can fix this by first putting your aquarium in complete darkness for a day or two and by replacing your LEDs to prevent this from happening in the future. 

Is it dangerous to leave my LED lights on overnight? 

LED lights tend not to get hot like its competitors such as metal halide lights or fluorescent lights. That being said, it’s still a good idea to turn them off at night so the transformer has time to cool down so you can still avoid any potential risk of overheating. 

Furthermore, constant lighting on your aquarium is not beneficial for the aquatic life inside it either. Your fish definitely need some downtime so they can rest and develop a natural circadian rhythm.

How much light does a freshwater aquarium need? 

Light intensity in aquariums is usually measured in watts per gallon. Generally, most freshwater aquariums require about 3 – 5 watts per gallon of light for 8 hours every day.

How much light does a coral reef aquarium need?

Coral reef aquariums generally require a higher amount of light than a freshwater aquarium. In most cases, you will need somewhere between 4 – 8 watts per gallon of light for 12 hours every day in order to successfully run a coral reef aquarium.

Final Verdict

Your fish, plants and corals are all beautiful creatures that have brilliant, bright colors and patterns to display; It’s only fair that you invest in a decent lighting setup so their beautiful appearance can be displayed properly.
