Why use LED lights for aquarium plants?

LED aquarium lights deserve praise for their amazing features that are beyond compared to traditional fluorescent bulbs. Here is why: 

Long lifespan

Generally, LED lights are sold at a higher price than the standard lights such as halogen, fluorescent, or incandescent counterparts. However, LED bulbs last longer than the aforementioned lights, which turns out to be an economical way in the long run.

You can expect a LED light bulb to 10 or 20 times last longer than the traditional bulbs. So for a typical good LED aquarium light, it can stay with you for at least five years or more. 

Brighter but more energy saving

LED lights will deliver brighter and clearer light to your aquarium. This will greatly enhance the colors from the inside creatures, creating a beautiful and lively picture of a small aquatic world. What makes the LED aquarium light ideal is it’s brighter but doesn’t cost you more money on electric bills. With an equivalent light outcome as a traditional bulb, the LED counterpart will draw fewer watts, then save up your energy consumption.


Your aquarium fish and plants will definitely not enjoy a too hot environment. Luckily, LED lights are less likely to emit heat to the outside environment, keeping the aquarium water at an adequate temperature, which is ideal for aquatic creatures inside the tank to develop and behave naturally. 

What to consider when buying LED aquarium lights for plants?

You can buy the most modern and expensive LED light doesn’t mean you bring the best condition to the planted aquariums. There is so much more than just the price or technology to consider when buying LED aquarium lights for plants. Refer to the following factors that might affect how you choose the most suitable light for your fish tank:

Color spectrum

The good news is aquatic plants can grow under a wide range of the color spectrum. However, we should know that the RGB (Red, Green, Blue) colors are best for this environment. Therefore, when choosing LED aquarium lights, you can look for the ones that offer a full-color spectrum or either red, green, or blue shades rather than just a simple white color. 


As mentioned above, RGB is ideal for planted aquariums, but how bright should the lights be?  The exact answer will actually depend on the kinds of plants you are growing inside the tank. In fact, different plants require different light intensities, making it quite complicated to adjust the perfect brightness that suits any plant kind. 

However, we would say that a 6500K to 7000K color temperature is considered the most suitable range for the LED light outcome because it is closest to natural daylight. Our advice is you should start building your own fish tank with low-light-intensity plants such as anubias or crypts because these plant kinds are beginner-friendly. 

Tank size and light spread

You cannot just randomly pick a somewhat LED aquarium light from a store and install it in your fish tank. Before shopping, you need to measure the tank size to make sure that you will buy the light with the proper dimension. For instance, if you have a big and long aquarium, you might need multiple LED lights or a long-tube one that can cover and spread the light to the entire tank and deep down at the bottom. Thereby, plants at the bottom of the aquarium can receive a good amount of light to keep growing. 

In fact, most manufacturers provide aquarium lights that have a good one-foot light spread deep down. Some brands also offer higher-quality LED lights for fish tanks with a high degree spread (about 120 degrees), allowing the light to even reach outside the aquarium area. 

Features and price

Not all LED aquarium lights are the same, each manufacturer will provide different features on their lighting products. Some LED lights are equipped with new technology, such as remote control via smart devices, or color and light intensity changing based on a timer setting. As a result, the price for each kind of light will vary either. Generally, the more features the light has, the more expensive they are.
