The DLC will be switching to a new application portal for SSL and Hort applications on January 31, 2022. Any SSL and Hort applications that have been created must be submitted by close of business on January 31 in order to complete their review through the old portal. Any applications that remain unsubmitted on February 1 must be recreated in the new portal. There will be no change for NLC applications at this time. Click for more details.

Wednesdays • July 29th, Aug. 26th and Sept. 23rd

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

Session 2: Incentives vs. Regulations – What Do They Mean for Product Selection?

Wednesday, August 26, 2020 from 1pm-2:15pm EST

This roundtable will feature a discussion between cannabis/horticulture regulators and utility energy efficiency program administrators that compares their approaches to constraining energy use and increasing grower/licensee participation. Energy codes versus regulations, incenting beyond regulations, and key challenges for market transformation are a few of the topics we’ll tackle in this session.


  • Explore different approaches to constrain energy use in controlled environment agriculture.
  • Review challenges with accelerating adoption and offering incentives for products in states and/or regions where DLC listed products are required in code or regulations.
  • Understand how incentives can be structured to differentiate products above code.
