Horticultural Technical Requirements

Technical Requirements V3.0
Hort V3.0 increases the photosynthetic photon efficacy (PPE) threshold by 21%, placing the DLC threshold for LED-based horticultural lighting at 35% above the most efficacious non-LED option. V3.0 also introduces product-level controllability requirements, requirements for reporting the intended use of products, and a surveillance testing policy to maintain the integrity of the QPL.

Technical Requirements V2.1
As a minor update to the Technical Requirements, Hort V2.1 expands the range of horticultural lighting products eligible to be qualified on the Hort QPL, creating greater access to utility incentives for horticultural lighting manufacturers and providing more avenues to achieve savings for energy efficiency programs. Under V2.1, lamps, DC and PoE powered products, and actively-cooled products are eligible for qualification.
