Session 1: Evolution of the DLC Horticultural Lighting Specs and Rebate Program Models that Support Market Adoption

Wednesday, July 29, 2020 from 1pm-2pm EST
Immediately following from 2pm-3pm a 1-hour Discussion Group on Access to Rebates

Struggling with the difference between PPF and PFFR? SQD and PPID? This series of webinars will start with an overview of horticultural lighting industry metrics and will explore existing gaps in research and standardization. Some, but not all, utilities offer a custom incentive/rebate for LED horticultural lighting products which may take the form of $/kWh, kW or $ per fixture incentives. Panelists will discuss the evolution of their incentive programs in this roundtable and dive into the data needed for prescriptive rebates.


  • Review the metrics behind the DLC Technical Requirements
  • Understand some of the incentives available for horticultural lighting and how they influence market adoption
  • Understand industry challenges in providing prescriptive rebates for horticultural lighting and explore potential solutions


  • Utility staff
  • Growers
  • Implementers
  • Manufacturers
