Definition - What does Light Emitting Diode (LED) mean?

A light emitting diode (LED) is a small electroluminescent light. LEDs are energy efficient, and they emit little to no heat. These lights come in many different shapes and sizes, and have a wide variety of uses. LED lights have risen in popularity as grow lights within the field of horticulture, especially for urban farms and grow rooms.

In relation to horticulture, LEDs are very popular because they offer many benefits over traditional grow lights. One major benefit over traditional lighting is that LED lights have a much longer lifespan. This is very important for greenhouses or other indoor growing spaces where constant light is needed.

LED lights can last up to 100,000 hours, therefore reducing maintenance time and cost. Another crucial benefit is that LEDs put out far less heat than traditional lighting methods, which is important because too much heat can damage plants. In addition, LEDs consume far less energy, and when implemented correctly can reduce energy consumption as much as 75 per cent.

LEDs are also beneficial when gardeners need a particular wavelength of light to be emitted. Most plants flourish under both red and blue light. However, different plants require different amounts of the red and blue wavelengths, which different color LEDs can provide.
