All you need to know about LED Grow lights

Last Updated on August 15, 2020 by Daniel Cooper

LED’s are certainly not a new technology but their continuous development has led to newer and better lighting technologies that are particularly useful when it comes to indoor farming. This evolution has made them very popular because the lights enable farmers to achieve optimal plant growth with little effort. To get a sense of all these below is everything that you need to know about this lighting technology while also showing why it is better than the rest.

Know about LED Grow lights

1. They are Energy Efficient

One of the main reasons why LED grow lights have been largely adopted is because they consume a very small amount of energy. This energy input is usually measured in Watts and it generally refers to the amount of power that the bulb consumes per time.

Structurally, LEDs do not have filaments, gases, or anything that makes them lose some energy in form of heat. This results in high conversion of the power input to visible light and this is what makes them extremely efficient.

2. They are Controllable

As much as the sun’s light is beneficial to plant growth, there are some light wavelengths that plants do not require in this light. With LED grow lights, it is possible to control the light spectrum so that you can give the plants a huge dose of what they need most at their growth stage.

Blue and red light wavelengths are the most important ones for plant growth and consequently, are part of the wavelengths defined as the Photo-synthetically Active Radiation (PAR).

You can control an LED light to produce red light for flowering or fruiting plants and blue light for leafy plants, giving the crops the best growth conditions.

3. They Produce Less Heat

By producing less heat than other lighting systems, LED grow lights enable you to place the plants closer to the light, leading to maximum light absorption. Plants also transpire more when it is hotter and thus, this cool environment will make them use less water. This will translate to water bill savings because less water will be used for farming.

4. They are durable

While other lighting systems have a lifespan of 2 – 3 years max, high quality LED grow lights can remain operational for up to 10 years. This is one of the biggest benefits you will get from such lighting systems because you won’t have to worry about replacing them for quite some time.

5. They are small but emit a lot of light

The final thing that you need to know about LED grow lights is that they are usually very small but emit a lot of light. This gives you the benefit of planting multiple plants in a squeezed space because the light produced per square foot will be bright enough to cater to the squeezed plants.

Therefore, you can produce more output per the same amount of space as compared to when using other types of grow lights.


The only downside to LED grow-lights is that they are expensive to manufacture and thus, are expensive to buy. However, with their long lifespan, the cost factor becomes a minor issue since they will serve you for a long time before requiring replacements.
