Best Light For 5 Gallon Planted Tank (Get The Best One For You)

Regardless of the size of the tank, finding the best light for plants is crucial for planted tanks. With the appropriate illumination, you can keep your plants healthy and enhance the color of your tank. 

However, finding the perfect lighting for a small tank can be challenging. An algal problem will ensue if the light is too bright or the plants die slowly from lack of light intensity.

Smaller-than-5-gallon fish tanks, known as “nano tanks,” are notoriously difficult to have the ‘perfect light’ because of their wide range of forms and sizes. 

For the most part, this issue may be remedied by using clip-on LED light fixtures. In addition to being simple to install on nano tanks, these items also supply ample illumination for the tanks.

In this blog post, we’ll be reviewing some of the Best Light For 5 Gallon Planted Tank. So if you’re interested in keeping plants in your tank, keep reading!

How Many Watt Do You Need For 5 Gallon Planted Tank

If you have a fish-only aquarium, you’ll need about 1 to 2 watts of lighting per gallon, 2 to 5 watts per gallon for freshwater planted aquariums, and about 4 to 8 watts per gallon for reef tanks.

Using 10-watt lights for a planted tank of five gallons can be a good place to start. In some cases, though, these criteria may be more lenient.

Buying The Best Light For 5 Gallon Planted Tank: Things To Consider 

Buying The Best Light For 5 Gallon Planted Tank Things To Consider

Intensity Of Light

The PAR (Photosynthetically Active Radiation) wavelength ranges from 400 to 700 nm and is critical for plant growth. Photosynthesis and development in plants can be aided by light in this spectrum.

All manufacturers do not publish the PAR value because it varies substantially depending on the depth of the tank.

Human eyes can distinguish between four primary colors: blue, red, green, and white, which make up the electromagnetic spectrum. Aquatic plants require all of the colors in the spectrum to thrive.

Optimal plant development can be achieved with at least 50% red light, 35% green light, and no more than 15% blue light. But there’s no need to stress your aquarium plant’s light needs while being grown with LEDs.

Light Spectrum

A plant can thrive as long as the light spectrum is between 2700K and 10000K. In a planted aquarium, anything outside of the 10000K range tends to fail (beyond that, lights become too blueish)

In terms of lighting, you can pick between 6500K and 7000K (the most popular choice among fishkeepers), which is similar to the sun’s light.

In reality, you have complete freedom to choose the color spectrum of your aquarium light, except for a very blue light (which is used for growing corals).

Types Of Plants

Light intensity is mainly determined by the aquatic plants you intend to have in your aquarium. It is possible to group plants into low-light, medium-light, and high-light plants.

Low-maintenance plants like Anubis, Java moss, and Ferns can thrive in low-light conditions. Moderate light levels are ideal for stem plants and a few other plants.

To keep up with the rapid plant development and prevent algae blooms, you may require a CO2 supplement for high-intensity lighting.


Don’t scrimp on essentials like an aquarium light, even on a tight budget. When something is cheap, it’s usually riddled with flaws and won’t last or meet your needs. As a result, it’s always best to spend the extra money and get something more reliable.

Final Word

So there you have it. Our top picks for the best light for a 5 gallon planted tank. Hopefully, this article has been helpful, and you are now one step closer to finding the perfect lighting for your aquatic friends. 

Finding the correct lighting for your aquarium is the most difficult challenge for most aquarists. Smaller tanks like 5-gallon, which have a limited selection of alternatives, are more likely to have this problem. However, for most small tropical fish/shrimp aquariums, these LED lights may be clipped onto the aquarium.
