LED vs Traditional Grow Lights

LED’s are considered efficient for several reasons. One of which is that they can be customized to provide the exact colors that plants need leaving out the colors they don’t.

For the best all-around growing conditions for all parts of a life cycle LED lighting should contain some:

  • Red LEDs (600-700 nm)
  • Blue LEDs (400-500 nm)
  • Some Green LEDs (500-600 nm)
  • Some Far-Red LEDs (700-800 nm)
  • Some White LEDs
  • Some IR. UV LEDs


There are many LED grow lights are configured with the proper spectrum for all stages of growth, meaning you can use the same light for the whole grow.


Traditional Grow Lights

When we say traditional grow lights we pretty much talking about everything not LED. This includes fluorescent, HID, and CFL lighting.

These lights do not emit the single colors that LED lights do. When looking at the light emitted by a typical glow light we usually see either a bright daylight or a soft yellowish hue.

Typical grow light is measured by color temperature in the measurement of “Kelvin”.

At the lower end of the scale, the red spectrum of light, is the soft hue, At the other end of the scale, you have more of the blue spectrum of light, the daylight hue.

In addition to the red and blue spectrums, even though we can not see it, there are the other color spectrums being given off by these lights as well.
