What Makes LED Lighting for Aquariums Different?

The most popular types of aquarium light for fish tanks are fluorescent and LED aquarium lighting.

Fluorescent fixtures use mercury vapor and a ballast, running electricity through the tube to create a glowing bar of light.

The benefit is that they are more efficient and run cooler than incandescent bulbs. But they are larger, and the ballast takes up even more room.

Fluorescent tubes for aquarium lights

Using LED lighting for an aquarium light offers several benefits. Each unit is actually composed of dozens to hundreds of individual LED bulbs.

Each LED (light-emitting diode) bulb is a semiconductor that emits light when a current is passed through it. Unlike fluorescent lighting, they are tiny and also run even cooler.

Aquarium LED light fixtures also last longer, typically between 25,000 and 50,000 hours of runtime. This adds up to nearly 7 years of continuous run time for 12 hours per day!

What Are the Benefits When Using LED Lights for Aquariums?

Besides running cooler and more efficiently, there are several benefits to using LEDs as aquarium light! For starters, each LED bulb burns out individually, rather than an entire set or fixture burning out all at once.

This means you can replace individual bulbs over time if you’re good with tools, extending the lifespan of your aquarium LED light infinitely.

Each LED aquarium lighting unit is also much more easily customized for specific purposes. This is because they are built one LED at a time. If you have plants that need a little more red, you can find LED aquarium lighting that meets that need.

If you prefer stronger actinic lighting when looking at your tank – but also want regular white light for general photosynthesis, many aquarium LED light options can toggle between both outputs with ease!

There are no heavy metals like mercury are used in their construction, lessening their environmental impact compared to compact fluorescents and metal halide lighting.

LED lighting fixtures are also not fragile like fluorescent tubes, which break if dropped and often crack if splashed when running hot.

Things to Think About Before Buying Aquarium LED Lights

What Is the Main Reason You Are Buying an Aquarium Light?

This might sound a bit silly, but the reason you are buying an aquarium light actually matters a lot. There are many features that plant and coral LED lights have that you might not want to pay for if you are lighting up a fish-only aquarium.

And vice versa; the needs of a fish-only tank are mostly aesthetic in nature. You can use dim LED aquarium lights or lights that output unique colors so long as they make the tank look as good as you wish!

What Are the Needs of Your Aquarium Animals and Plants?

If you are buying an aquarium light to provide radiation for plants or coral, you’ll need to be sure that you’re buying the right intensity and color temperature. If you keep mostly low light plants, a light that’s higher in intensity might still do them good and boost their growth.

However, if their growth can’t keep pace with available nutrients, then you’ll see an immediate boost in algal growth as well.

LEDs and Photosynthetically Active Radiation

Photosynthetically active radiation (PAR) is what’s most important when providing light for increasing plant growth. As you likely know, plants use sunlight to crack apart water and carbon dioxide, creating simple sugars that they use for food. However, not all light is created equally.

PAR is mostly in the green-yellow-orange spectrum, similar to the color temperature output by LED lights made for planted tanks (5600-7000K).

Incandescent lighting, which is used in many older aquarium hoods, has a warmer temperature of around 3-5000K, while fluorescent lights can go anywhere from under to well over this range, as high as 10,000K (actinic lighting).

Many of the best aquarium light fixtures for coral mix in actinic light bulbs, which have the effect of brightening the colors of coral. Many species have fluorescent pigments that become positively vibrant with the right aquarium lighting.

Many species are also photosynthetically sensitive to actinic blue LEDs, though precisely how much is required is still a topic of intense debate.

Some aquarists find that providing purely actinic lighting or standard 5600K lighting is all that’s required for healthy coral growth, depending on the species. Others find that a mixture of the two light temperatures is best.

What Are the Dimensions of Your Tank?

The length of your tank only matters so much as to make sure that your new aquarium light reaches across without too much overlap. But the width and depth of your tank matter even more.

A bright light is very important if you have a deeper tank. Shallower tanks, such as a 20-gallon long (12 inches high), need less light intensity than a tank that’s taller, such as a standard 20-gallon tank (16 inches).

That extra 30% of height translates to needing as much extra light intensity if you want the same amount of light to reach the bottom.

If you’re growing corals, you can always move them closer to the light source. But if you grow carpeting plants like Dwarf Baby Tears or Monte Carlo, then there is no substitute for having an LED light that’s strong enough to light up the bottom properly!

Empty Aquarium

When buying a wide tank, such as a 40-gallon breeder or standard 75-gallon aquarium (both 18 inches wide), the light may be intense enough directly under the bulb or strip. But you will likely see significant falloff along the sides of the tank.

Depending on the fixture’s design, you may see as much as a 50% decrease in intensity along the sides of a wider fish tank versus directly under the fixture.

In this case, buying two fixtures will give you better coverage along the sides, ensuring all of your corals and plants grow naturally! Some aquarium LED light models are designed to spread their output fully across the bottom, but this usually comes at the cost of total light intensity.

What Features Are Included With Each LED Light Option?

Besides the LED lights themselves, you should also think about what features each aquarium light has to offer. Are you looking for water resistance?

Some of the units here are only protected via a plastic or glass guard, while others are fully waterproof and can even be briefly submerged.

Some use LED bulbs with color temperatures maximized for coral viewing pleasure or plant photosynthesis. Are you looking for a remote control to operate the unit? Weather simulations, timers, and so on…

There are many additional features that will influence your buying decision of any aquarium lighting. Having a list of “must-haves” for your fish tank light can make shopping easier since you can then make informed decisions on which “nice-to-haves” are worth spending a little more on!

What Sort of Budget Do You Have to Work With?

Lastly, you should carefully consider the budget you have to work with. Some of the most affordable LED lights don’t have the customizable controls and other features that pricier models do.

You’ll likely have to pay extra for the top-shelf features. But if you’ve invested thousands of dollars into a mature coral reef tank, there’s little reason not to provide them with the best quality lighting!

LED Light Fish Tank Frequently Asked Questions

Are LEDs Good for Plants When They’re Growing?

Absolutely! While they run cooler than fluorescent and incandescent lights, LED fixtures offer bright lighting for plants that’s both cool running and power efficient!

Does the LED Light Spectrum Affect the Growth of Plants?

Yes, the light spectrum is very important when choosing an aquarium light. LED lighting that’s too warm (below 5600K) or too cool (greater than 7000K) is less efficient for photosynthesis to occur and can cause plant growth to slow or stall out entirely, no matter how bright your aquarium light is.

The same is also true for coral in reef tanks, except that they can use light as cool as 10,000K+ (actinic lighting) for photosynthesis.

Will My Aquarium Plants Grow Under LED Lights?

Yes, plants grow as readily under LED lighting systems as they do under fluorescent lights or even the sun.

Are LEDs Really Better than Fluorescent Tubes?

LED lighting offers several advantages compared to fluorescent light tubes. Fluorescents run hotter, take up a lot more space, don’t last as long, and are very easy to break.

LED lighting systems use less power, are cool to the touch, can be as slim as a few inches across and a few millimeters thick, and are typically very durable.

How Long do LED Aquarium Lights Last?

An Aquarium LED (light-emitting diode) will last anywhere from 25,000 to 50,000 hours of continuous run-time. That’s up to 7 years of usage if run for 12 hours per day.

Many aquarium LED light manufacturers give ratings for their bulbs. And since the diodes burn out individually, they can be replaced one at a time!

Do LED Aquarium Lights Cause Algae?

underwater shot of clownfish

Any light source can cause algae to grow since algae is a plant. So providing the right intensity is important. In fact, LED aquarium lights are less likely to cause algae so long as they provide a proper spectrum of light for your plants or corals to grow.

Healthy plants and corals will out-compete algae for nutrients. On the other hand, poor lighting will make plants and corals unhealthy, which can cause algae problems to arise.
