Key Aspects To Consider When Buying Aquarium Lighting for Plants

It’s important to consider all your needs before buying an LED lighting system for your aquarium. Here are a few things to keep in mind:

Plant Type

For plants to grow and perform photosynthesis, they require different levels of light intensity. Some plants require intense lighting while others thrive on subtle lighting, such as mid-ground plants. The number of plants in your aquarium also influences the type of LED system you should put in your aquarium.

Exposing your plants to brighter light for longer periods of time will help them develop better. In a nutshell, knowing what kind of plants you have in your aquarium will help you choose the correct LED lights for them. If you wish to limit the growth, use aquarium LED lights with lower wattage.

Light Color

A light’s color is determined by its spectrum, which is measured in Kelvin. The spectrum of freshwater plants can be broader. Anything between 5500K and 6500K should be fine for them. However, for saltwater corals to grow and develop, they require a specific actinic light.

Saltwater or Freshwater

You need to set up your LED lighting system differently for a saltwater aquarium than you do for a freshwater aquarium. For corals to thrive in saltwater aquariums, specific actinic light is needed, while for plants to thrive in freshwater aquariums, it is not necessary. As bright blue light does not benefit plants in a freshwater aquarium, you must consider the aquarium you have before choosing a lighting system.


As mentioned earlier, there are countless lighting systems for aquariums in the market. Each alternative offers unique features that are ideally suited to certain types of fish tanks. That’s why you should take your aquarium type and requirements into account before investing. When purchasing your aquarium setup, the goal is to avoid wasting money on unnecessary features that are incompatible with it.


In this article, we discuss several devices that are easy to use, long-lasting, simple to use, and will help your plants grow to their fullest. Finnex’s Planted Aquarium LED Light stood out to us as the best among all the lighting systems. It is made for smaller planted aquariums, making it perfect for betta tanks.
