The DLC is pleased to announce the final release of Horticultural Lighting Technical Requirements Version 3.0, with a proposed effective date of March 31, 2023. At the same time, Surveillance Testing Policy Version 3.0 is released, Planned Round 1 Surveillance Testing is expected to begin in Q1 2024. 

The main changes of DLC HORT V3.0 are as follows:

Change 1: Increased efficacy threshold

The Hort V3.0 PPE threshold has been increased to a minimum of 2.30 μmol × J -1, the -5% tolerance for PPE has not changed with this revision.  

Change 2: New requirements for reporting intended use of products, dimensions, and images

To support the development of prescriptive/midstream energy efficiency incentive programs, Hort V3.0 will collect and report application (intended use of product) information of listed products to give users insights into the intended controlled environment and lighting scheme for all listed products. Additionally, product dimensions and a representative image are required and will be published on the Hort QPL.

Change 3: Introduction of product-level controllability requirements

To enable additional energy savings, promote interoperability, and lay the groundwork for future demand-response systems and programs, Hort V3.0 will require dimming capability for certain AC-powered luminaires, all DC-powered products, and all replacement lamps.

Hort V3.0 also requires reporting of additional controllability details, including dimming and control methods, connector/transmission hardware, and integral control capabilities.

Change 4: Introduction of LM-79-19 report

Only tests performed according to the 2019 version of LM-79 (ANSI/IES LM-79-19) will be accepted for new applications.

Change 5: Introduction of a surveillance testing policy

To protect the integrity and value of the Hort QPL for all stakeholders, the DLC will actively monitor the validity of data and other submitted information through a surveillance testing policy. The first round of surveillance testing will begin in the first quarter of 2024 for DLC HORT V3.0 listed products
