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.
