The Best LED Lights for Planted Tank Reviewed 2021

When you’re looking for the best LED lights for planted tank, there’s one big thing to keep in mind. You’re not just looking for lights that will make your aquarium look pretty.

The plants inside your aquarium depend on that light for survival. That said, you must also remember that too much light can cause problems, too.

There are a lot of factors that go into deciding what LED lights are the best for planted tanks.

How to Choose the Best LED Lights for Planted Tank?

In order to choose the best planted tank lighting, it’s important to keep a few factors in mind.

First, make sure that you’re getting a reliable product. One way to do this is to make sure you choose a well-known brand with a good reputation. Good LED lights will be consistent and put out the same amount of light over time. Pick LED lights that are durable and will last. It’s also a good idea to keep in mind how difficult the LED lights are to install so you can choose one that isn’t unnecessarily complicated.

In order to make sure your plants are getting enough light, pay attention to the light spectrum. This refers to the colors of the spectrum that are actually present in the light. The broader the spectrum, the better the light will be for your plants because it will promote more efficient photosynthesis. The Kelvin rating or lumen is another thing to keep in mind to determine the temperature of the light and how it will affect your plants. Look for LED lights with 6500 to 7000K.

Speaking of light, you can find some models that allow you to control the settings to make it look like various times of day inside your aquarium. This is a purely cosmetic feature that can give the room a different look depending on whether it’s morning or night. If you decide this is something you want, make sure to find LED lights with settings that are easy to control. You don’t want to spend too much time looking for the right combination.

Cycles are also important to make sure that your plants aren’t getting too much light. If the LED light you use has a preset day/night cycle or an automatic timer, this will make it a little easier to make sure you’re giving your plants just the right amount.

From a more practical perspective, make sure that your LED lights have good ventilation. All lights produce heat and it’s important that it can dissipate properly. A splash guard is also another feature to keep the lights safe from being too close to the water.

Planted Tank LED Lighting – FAQ

How many lumens for a planted aquarium?

Lumens are more important for what you see than what your plants need. This is mostly because, while a lumen tells you how bright the light will appear to the human eye, we see different light than what plants need. Plants thrive on red and blue light so you have to make sure you’re providing enough to give them what they need.

For a rough guide, consider trying 5 to 10 lumens per gallon.

How much light is required for aquarium plants?

It depends. Light is the single most important factor when you’re growing plants in your aquarium. The reason is simple – plants need light to grow. Lumens are a measurement of light and how much light you need depends on a number of factors. Two of the biggest things to consider are: What kind of plants are you growing? How large is your aquarium?

As far as what plants you’re growing, you should know what their light requirement is. Some plants need a lot of light, some don’t. One thing to keep in mind is that plants requiring a lot of light are often more difficult to grow. So many factors have to be just right for these kinds of plants to flourish. You’ll have to consider more than light and pay closer attention to any changes in the water, maintaining and pruning the new growth, and how to or even if you should use fertilizer.

At the same time, too much light can also breed too much algae. Low light plants tend to be a little easier to grow just because there’s less to worry about.

How many hours of light for aquarium plants?

This is actually really important and the reason that so many of the better LED lights have been designed with a 24-hour cycle. Aquarium plants should get light anywhere from 8 to 12 hours a day, which makes a lot of sense if you think about it. In nature, these plants are only getting light when the sun is up, not 24 hours around the clock.

If you find that your tank is growing too much algae, it could be a sign that there is too much light. You can change this by using less light for the same amount of time or by shortening the amount of time that the lights are left on for about 8 hours.

These are all reasons why having an LED light with a preset or programmable cycle make things a little easier. You won’t need to worry about whether or not you forgot to turn the light off or if you’re helping breed more algae. Automatic cycles and times take care of these things for you.

There are a few exceptions. When you introduce new plants, leave the light on for a little longer to give them time to take hold and flourish. Stop and go back to a more normal schedule if you see algae appearing. You might also think about leaving the lights on a little longer in the winter because there will be much less natural light available.

Conclusion

As you can see, choosing the best LED lights for a planted aquarium is really important. The right light is more than a way to make your tank look nice. It’s the most important aspect of having a thriving plant life.

While you may not prefer something with preset cycles and timers, in the end, these really will make it easier on you when it comes to maintenance. These features are the best way to make sure that your plants are getting the right amount of light because they follow a more natural cycle. Your plants basically get a simulation of the kind of day they’d have if they were growing in the wild and truly depending on the sunlight.

Still, if you prefer to have more control for whatever reason, there are plenty of great choices available. Just make sure you pay close attention to the length of time you leave the light on so your plants can thrive in algae-free environment. Your plants (and fish!) will be happy and you’ll end up with a beautiful tank to look at and enjoy.
