Energy Optimization for Horticultural Lighting
As a rapidly growing sector, controlled environment agriculture is ripe with potential for energy savings, and installing energy-efficient LEDs from the get-go can improve crop yields while reducing climate impact. The DLC’s Horticultural QPL is the first Qualified Products List for energy-efficient horticultural lighting. Growers rely on the Horticultural QPL to validate performance claims so they can find efficient and effective indoor lighting options for their crops and keep up with cutting-edge technologies. Together, we can improve the efficiency of sustainable indoor agriculture, and could save up to $240 million worth of energy every year through horticultural lighting optimization.

total possible annual energy savings if horticultural facilities switch to LED lighting
Updates to Horticultural Technical Requirements
The DLC has adopted a preset revision cycle for the Horticultural Lighting Technical Requirements and QPL to give greater predictability surrounding changes to end users.
The QPL will undergo 24-month major revision cycles focusing on efficacy and structural updates, and 12-month minor revision cycles focusing on administrative and process improvements.
