Hort V4.0 – New Technical Requirements Released

We are pleased to announce the final version of the Hort V4.0 Technical Requirements! This document was released as a draft in November 2024 and has incorporated changes from feedback received during the stakeholder comment period. Thank you to everyone who collaborated with us on developing these requirements.

By updating the Technical Requirements for DLC-listed Horticulture lighting products, we are improving the efficacy and quality of LEDs used for controlled environment agriculture (CEA). Accelerating energy efficient lighting in this growing sector will result in lower costs, energy use, and carbon emissions.

Manufacturers, utilities, testing labs, and regulators should note the three key updates in Hort V4.0:

• Increasing the photosynthetic photon efficacy (PPE) threshold 
• Removal of lamps as a category eligible for the QPL
• Clarifications to various requirements throughout the new policy

Further details can be found via the links below. 

Join us for a webinar about the new technical requirements on 3/25.
