Greenhouse LED lighting study results:

"US (MN): "43% energy savings under LEDs compared to HPS"

Two groups, Outsourced Innovations, a lighting consulting firm, and Tangletown Gardens, a greenhouse nursery and garden business, recently finished a one-year study. The research project, called LED Lighting to Improve Energy Efficiency in Controlled Environment Agriculture, aimed to show reductions in energy use from greenhouse-specific LED lamps compared to the traditional use of high pressure sodium (HPS) lamps in a controlled crop environment.

The key findings of the research are as follows:
  • Substantial energy savings (43%) was measured under LEDs compared to HPS.
  • Lumigrow LEDs fixtures were reliable and performed better than stated on energy consumption and power quality in this real-world application
  • LED equipment payback was projected to occur in 2.2 years
  • Moving crops closer to the LED light source produced intriguing outcomes in controlled environment agriculture.
In the video below, it is shown and explained how the research has been conducted.
