Best LED Lights for Planted Fish Tanks

How to Choose an LED Light for Planted Aquarium?

Since you already know that choosing the ideal LED light is the best thing you can do for your fish tank, then you better be careful with what you settle on.

Note that it’s not only about the lighting, you also need to put into consideration the growth pattern of the fish and aquatic plants.

Before we delve into our recommendations, you can begin the filtering process from these specifications.

Size of Aquarium

When choosing a LED light it is important to fit the length of your aquarium. However, you need to also take in consideration the height for your tank. Some LED lights have stronger light output, while other are dimmable and can adjust light level.

In a shallow tank you don’t want a very strong light, because that will only cause algae growth. For a taller aquarium, you will need a much stronger light, in order to provide the necessary light level for plants that are growing on the substrate of your aquarium.

LED Temperature

Light temperature refers to the number that is expressed in Kelvin. Lower Kelvin rating means warmer temperature, while higher Kelvin rating is considered cooler temperature.

The inner deeper parts of an ocean are darker than the upper parts. Well, when light passes through water, only the colors with stringer wavelengths make it past to the deepest part of the water column. Those with lower wavelength strength are absorbed, resulting in the darkening of the deeper areas.

LED light usually designed with light temperature of up to 20,000 K, which what most marine animals like.

On the other hand, freshwater planted tanks like much warmer light temperature, while they live in much shallower waters. Most freshwater aquatic plants thrive under 4,500-8,000k rated LED lights.

Aquatic Plants

As mentioned before, some aquarium plants require more light, while others plants can thrive in lower light conditions. Before you choose a LED light for your planted tank, you have to know what type of plants you are going to plant.

LED Lights Durability

You don’t want to buy something that won’t last. There are many companies that manufacture LED lights for aquariums. BUt which should you choose? Which aquarium LED lights are the most durable?

There are some questions that you may have in your minds before you make a purchase. The following are some of them and their answer according to experts’ view.


What Kelvin rating LED Light Should you choose?

This is a question that many ask, but because of lack of accurate information, they make mistakes that cost them in the long run.

Let’s set things straight. According to research done by “that Fish blog,” LED lights to come with different Kelvin rating from 5,000k to 20,000k. The higher the Kelvin rating, the higher it mimics the deeper environment.

With this in mind, the right Kelvin rating will depend on what you want to put into the water. If you are still in the dark, this example may help.

The daylight spectrum is suitable for freshwater fish tanks. Their Kelvin rating runs from 5000 to 10,000k. On the other hand, saltwater aquariums need higher Kelvin rating spanning from 6700k to 20,000k. This is ideal for reef aquariums.

What is the Ideal Lumen for Planted Tank?

The answer to this question will depend on your choice of the plants. However, the common ground for all plants begins at 10 lumens per liter. Below that may cause damage to the plants.

Now, light-hungry aquatic plants will not survive with such light. They’ll thrive in fish tanks with 40 lumens per liter. Medium plants would fall on the category that needs 20-30 lumens per liter.

All in all, the ball is in your court to determine the type of plant in the fish tank.

What PAR Value does Aquarium Plants Need?

A research done by Aquarium lighting helped to bring light to this controversial question that many have failed to wade through.

To begin with, PAR means the amount of light that passes through water that the plants use to photosynthesize. So the higher the PAR value, but not too much since it also has its downsides.

In their conclusion, the Aquarium lighting experts found out that PAR is divided into three categories of plants.

These are low light plants, medium-light plants, and high light plants. Their PAR level is 15-30, 30-80, and 80 plus, respectively. So if you know your PAR level, you can easily gauge your plants’ PAR level.

Do Aquarium LED Lights Produce Heat?

To answer this question, we can experiment. Use a standard bulb with at least 60 watts in a cold room for one hour and then exchange it with an LED bulb.

What’s your experience? You must have noted that the temperature increases when you used the standard bulb was more than when you used an LED light.

True to this experiment, Aquarium LED lights use 80% less electricity than the typical aquarium lights. So, they indeed generate heat, but in smaller quantities that’s not harmful to the fish or aquatic plants.
