Plant cultivation is one of the largest pillars of human life. Humans would not survive if plants ceased to exists. Plant cultivation technologies have continued to evolve over time. Farms, both big and small, are making use of top technology to propagate cash crops. Some people grow plants as a hobby and for fun. At the center of plant growth technology is LED Grow lights. LED grow lights have been around for quite a while now. This is a comprehensive guide that explores what they really are, as well as the pros and cons of using them.

What are LED Grow Lights?

Let’s begin with what grow lights are in general. Grow lights are lights used in plant propagation. They are designed to produce a specific type of illumination, and them hanging over the plants. Some even look like your average light bulbs. There are many types of grow lights. Incandescent fluorescent grows light has been in use for long, but they are now being phased out by LED grow lights. LED grow lights use a combination of many LEDs to provide the needed illumination. LED grow lights are now preferred because they are energy efficient, and have a longer lifespan. LED lights consume on a fraction of the energy consumed by the fluorescent lights with similar illumination.

LED grow lights are the present and the future as far as plant growth technology is concerned. The LED grows light technology continues to improve with every daylight. The idea is to ensure the lights consume as little energy as possible, without affecting their efficiency. There are many other advantages of using LED lights over the other types. Let’s explore some of the pros of using LED grow lights.


The following are the five main advantage of using LED grow lights.

  • Improved Lifespan – As compared to the increscent fluorescent lights used before, LED grow lights have a longer lifespan. They can last up to 100,000 hours. Also, LED grow lights do not just suddenly stall. They reduce brightness slowly as they deteriorate.
  • Full Spectrum Wavelengths – The LED grow lights have full spectrum wavelengths. You can provide a targeted wavelength for your plants. You do not have to buy another light when you need a different light wavelength.
  • Low energy consumption – LEDs are semiconductors. They, therefore, consume very little energy as compared to the fluorescent lights.
  • Flexible Designs – LED lights are designed to be very flexible. You can use them as ceiling lights, vertical lighting systems, or inter-lighting systems.
  • They have less heat dissipation and stronger light intensity


  • The lights produce directional light. The light is illuminated in one direction only. This means they have a smaller coverage.
  • LED grow lights are generally more expensive than the other types of grow lights
  • LED grow lights produce blue light, UV and IR radiations that are harmful to humans.
  • They are very sensitive to temperature changes. The LED bulbs are made of semiconductor diodes that are susceptible to temperature changes.
