Planted Aquarium Lights

The proper lighting is crucial for owning a successful planted aquarium. Choosing the best LED planted aquarium light is one of the most essential aspects of maintaining a planted aquarium. You should consider its color, light intensity, your budget, etc. Read this article and learn how to pick the best planted aquarium light. We also list the 5 best planted aquarium lights for you to choose from.

How To Pick The Best Planted Aquarium Light

Color Spectrum

Since aquarium plants can grow in a wide range of Kelvin temperatures, the color spectrum actually doesn’t matter that much when it comes to growing them. We don’t want to look at aquarium lights that are too red or blue, so the decision mostly comes down to personal preference.

Since this neutral white light is thought to most closely mimic natural daylight, many hobbyists prefer to use it. Simply put, you can choose a light with almost any color spectrum as long as it isn’t too blue (like those used to grow saltwater corals).

Light Intensity

How bright of light should you get? First of all, it depends on the kind of aquarium plants you want to grow. Anubias, cryptocoryne (or crypts), ferns, and other low-maintenance plants can be grown under low lights (or low-intensity lights).

With the exception of the picky carpeting plants, medium lights are ideal for stem plants and the majority of other species. Any kind of plant can be grown in high lights, but to keep up with the rapid plant growth and reduce algae blooms, carbon dioxide (CO2) injection is frequently necessary.

Since low-light plants are some of the hardiest, most beginner-friendly species, we advise most people to start with them because of the complexity that comes with high-light planted aquariums.

Light Spread

How much the light disperses or spreads is the final category to take into account. The majority of aquarium lights have a good 1-foot light spread directly below them, which means that plants outside of that window won’t receive as much light and possibly won’t grow as well.

Planted Aquarium Lights

In contrast, a shop light has a broad light spread because it is intended to illuminate an entire space. (Just remember that a shop light’s color spectrum might not accurately depict the hues of your plants and fish.)

Plant Type

Different species of plants require different levels of light intensity to grow and perform photosynthesis.

While some plants need very strong lighting, others, like plants that grow in the middle of the ground, benefit from subtle lighting. Not only that, but the number of plants in your aquarium also influences the type of LED system you should have in your fish tank

If you want to promote better development in your plants, expose them to a brighter light source for a more extended amount of time.

Use aquarium LED lights with a lower wattage if you want to restrict growth. In other words, knowing the type of plants you have in your aquarium will help you choose the right LED lights for them.

Light Color

The spectrum, which is measured in Kelvin, determines the color of light. Freshwater plants are more tolerant and may use a broader spectrum than saltwater plants.

For them, temperatures between 5500K and 6500K are sufficient. However, saltwater corals require a specific actinic light to grow and develop.

Saltwater Or Freshwater

There is a significant difference between how you install your Setup instructions for a freshwater aquarium’s LED lighting system and a saltwater aquarium. Corals in saltwater aquariums need specific actinic light, while the plants in freshwater aquariums do not.

Plants in a freshwater tank do not benefit from the intense blue light. In order to properly light your aquarium, you must first take into account the type of aquarium you have.


Numerous aquarium lighting options are available, as was already mentioned. Each alternative has distinctive qualities that work best with particular kinds of fish tanks.

That’s why you should take your aquarium type and requirements into account before investing. The objective is to buy the best aquarium setup you can without spending money on extra features that won’t work with your aquarium.
