Draft Horticultural Requirements V1.2 Overview Webinar

Horticultural Requirements V1.2 focuses on broadening the variety of horticultural fixtures eligible to be qualified on the DLC QPL and staying in line with emerging technologies and the state of the industry. This webinar, held on Tuesday, August 6, 2019 at 1:00 pm ET, reviews the proposed changes, which include:

  • Eligibility of DC-powered fixtures - starting on October 15, 2019, the DLC proposes that DC-powered fixtures are eligible for listing on the DLC Horticultural QPL.
  • A revision to the flux maintenance policy - the DLC will begin requiring flux maintenance data in horticultural-specific units, and will no longer accept lumens or radiometric watts LM-80 or LM-84 reports starting on October 15, 2019.
  • A revision to the TM-33 requirements - the DLC is proposing to delay its required implementation of the TM-33 format by one year and maintain the current method of reviewing and publishing data on PPID and SQD
