High Intensity Discharge (HID)

Applications:

HID lighting is traditionally used for applications that require higher light intensities than fluorescent lighting, such as cereal, forage, citrus and C4 plants.

Benefits:

  • Well suited for promoting leafy plant growth
  • Produces brighter light than incandescent, fluorescent and LED lamps

Considerations:

  • Shorter rated average lamp life than fluorescent and LED lighting
  • Generates significant heat and often must be positioned a considerable distance from the plant canopy
  • Unsuitable for rapid cycling of lamps due to slow lamp restart times
  • Limited ability to dim lamps
  • Introduces significant heat into the controlled environment, creating vertical temperature gradients
