Handpicked Review of The Best Aquarium Light for Plants

Let’s look at our list of the best LED lights for plants.

1. Finnex Planted Aquarium LED Light


  • 24/7 light cycle
  • Can be customized
  • Value for money


  • The 24/7 cycle is not customizable

General Characteristics

The Finnex Planted+ 24/7 Aquarium LED is a low-profile LED light with an ultra-thin profile. The light is equipped with a set of legs that firmly place the device on your tank’s surface. These legs are adjustable to fit smaller tanks, include screws for rimless tanks and a detachable inner section for larger rimmed tanks.

Lighting Power

It is aimed to care for a large number of the plants in your aquarium. To provide the appropriate lighting, the fixture has strong LED bulbs that can produce 7000K daylight. This light, like actual sunshine, is vital because it helps aquarium plants in photosynthesis.

Photosynthesis requires about 8-10 hours of light every day for the plants in your aquarium. However, excessive lighting is harmful to your fish and plants. Therefore, it is essential to turn off the lights on time. Fortunately, the Finnex Planted+ 24/7 LED light includes a controller that can automatically turn on the lights and switch them off when required.

The controller is programmed with a 24-hour automated lighting cycle, which provides a hands-free operation without any hassle. The 24/7 function also simulates the sunrise and sunset in nature, giving your aquatic plants a sense of the natural day and night cycle.

Integrated Colored LEDs

Apart from ensuring proper plant growth, the Finnex Planted+ 24/7 includes blue, green, and red LEDs. They offer various lighting effects that add to the appeal of your tank both day and night time. However, if you don’t want to use the 24/7 preset on this device, you can cycle through some ready-to-use presents built into it and choose the one that suits your preference.

The 24/7 cycle begins in the morning, progresses to a rising sun, and ends at noon. It then develops into a red sunset and, eventually, starry blue moonlight. On the next day, the lighting cycle is repeated on time. It is automatically regulated by the built-in controller, removing the need for daily fixture management.


The lighting system is made of high-quality aluminum, which provides adequate cooling and heat dispersion and increases its durability. Additionally, it is equipped with a  water-resistant splash guard that adds to its durability.

To control this light, you must first download the app that enables you to modify every element, including the color, brightness, and time. Although this fixture includes numerous pre-programmed lighting cycle options, you can easily create your own using the app.

It is easy to set up the light for a 24-hour cycle, and you can decide when it starts and ends. As it rises to full daylight mode, it will go through a morning cycle. The light will then begin to dim at the next preset time for sunset. You can then specify how long you would like the moonlight to continue before turning off for the night. We encourage experimenting with the light spectrum in the day and night sections of the mobile application.

Once you modify the settings, there is no way to automatically restore the light to its default configuration values. So, make sure to list down the light preset settings before you begin experimenting with it.

Easy Installation

When it comes to installation, the Fluval 3.0 lights provide a lot of conveniences. It features extendable brackets that can be adjusted smoothly, allowing you to manage the light to match your tank.

Key Aspects To Consider When Buying Aquarium Lighting for Plants

When it comes to choosing the best LED aquarium lighting, it’s essential to consider all your needs. Following are a few factors you need to keep in mind before buying an LED lighting system for your aquarium:

– Plant Type

Different species of plants require different levels of light intensity to grow and perform photosynthesis . While certain plants require extremely intense lighting, others thrive on subtle lightings, such as mid-ground plants. 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. If you wish to limit the growth, use aquarium LED lights with lesser wattage. In a nutshell, knowing what kind of plants you have in your aquarium will help you choose the correct LED lights for them.

– Light Color

The color of light is determined by the spectrum, which is measured in Kelvin. Freshwater plants are more tolerant and may use a broader spectrum than saltwater plants. Anything between 5500K and 6500K will be enough for them. 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 LED lighting system for a saltwater aquarium and how you set it up for a freshwater aquarium. Corals in saltwater aquariums need specific actinic light, while the plants in freshwater aquariums do not. The bright blue light is not beneficial to plants in a freshwater tank. Therefore, you must consider the type of aquarium you have before investing in a lighting system for it.

– Cost

As mentioned earlier, there are countless lighting systems for aquariums in the market. Each alternative offers unique features that are best suited for certain types of fish tanks. That’s why you should take your aquarium type and requirements into account before investing. The goal is to purchase the best possible setup for your aquarium without investing in unnecessary features that are incompatible with your aquarium.
