The chart below compares the two most common types of lighting systems found in today’s greenhouses.

(High-Pressure Sodium Fixture)
(Light Emitting Diode)
Traditional LED Dynamic Lighting
(lights + software)
Wavelengths produced Fixed spectrum Fixed spectrum Able to alter/adjust the spectrum
The chart displays the different wavelengths for Sunlight, LED and HPS lights.
Blue light rays encourage photosynthesis, where LEDs shine.
Note: CFL, compact fluorescent lamps are not used in commercial growing settings, and commonly found in household applications.

Everything a traditional LED can do plus:

  • Enables growers to create a “light recipe”
  • 25% energy savings over traditional LED
  Drawbacks Relative to an LED fixture:

  • Shorter lifespan
  • Generate more heat when in use
  • Give more shade, having a wide reflector (fixture style)
Light is more directional, can target plant canopy.

Need knowledge & expertise to run these lights effectively.
