How to choose LED lights for planted aquariums?


There are many factors to consider when you are in the market for good quality LED lights for your planted aquarium. These factors include the product’s Kelvin Rating, PAR value, lumen value, etc.

The types of plants present in your aquarium are also an important variable. These parameters can help you determine which product is the best fit for your particular case.

Light color (Kelvin rating)


Color temperature (wikipedia.org)

The first factor to consider is the product’s color temperature, determined by its Kelvin Rating. For planted aquariums, a product that has a Kelvin rating of 7,000 to 9,000K is most desirable, as this range provides a simulation of a natural source similar to daylight.

Light quantity (Lumen)

Another aspect to consider when buying an LED light is that it provides enough light to the plants. This quantity of light is measured in lumen (Lm).

Since different aquarium plants require different levels of light to flourish, you must determine whether the plants in your aquarium are low light, medium light, or high light plants. This will determine how many lumens are required for your particular LED light, as the following information illustrates:

PAR (most common and easy to use)

Perhaps the most essential factor for plant growth is the PAR value. This value measures the amount of radiation required for photosynthesis and plant growth.

Generally, a higher PAR value promotes plant growth. However, different types of plants need different PAR levels to grow correctly. It is recommended that the plants be placed in varying locations from the source as per their requirements.

The manufacturer usually provides the specification values of an LED light. The following information can serve as a guide for plant needs:

Frequently asked questions

What happens with planted tanks without light?

In the absence of a light source, the plants will look for other sources to fulfill their needs. Every plant needs light to survive, but the amount required varies from one plant to the next.

For example, some plants with a lower light requirement can survive purely on the natural diffused sunlight in your house, while other plants with a higher light requirement require additional support.

How long should planted aquarium lights be on?

You may always be tempted to leave your new LED lights on but doing so will harm the aquarium’s environment. Fish and plants both require periods of darkness to simulate the day/night cycle. The recommended time for LED lights to be left on is 8 hours.

Why use a light timer?


It is incredibly convenient to use a timer for your LED lights if you forget to turn them off. They can also come in handy if you are not around for an extended period.

What happens if too much light, not enough CO2?

We can think of the relation of CO2 with light in an aquarium in a straightforward way. More light present in the tank will cause more CO2 to be required by the plants. However, if enough CO2 is not present, it can cause a breakout of algae in the tank, so it is imperative to find the right balance for your particular needs.

If, on the other hand, the amount of CO2 is increased without a corresponding increase in lighting, the plants will not photosynthesize well, and the CO2 level will reach such a level that it will become toxic to the fish and invertebrates.

Where to buy planted aquarium lighting?

The best place to shop for aquarium lights is on the Internet, as websites like Amazon provide many options, making it easier to compare products and identify what you are looking for.


The vital role LED lights play in the overall health and well-being of an aquarium, and its plants is clear to all. It is also an essential part of decorating the aquarium and making it look like a true attraction. Choosing one of the many options available in the market takes some prior knowledge as well. We hope this guide will enable you to make the best choice for your aquarium. Have fun!
