Revision Schedule and Listing Fees

Schedule of Technical Requirements Revisions

  • The DLC revises the Networked Lighting Controls Technical Requirements annually, with final revisions completed and released on June 1st of each year.
  • Each Technical Requirements revision is distributed through the DLC Stakeholder Input Process and comments will be considered for each revision. This process begins in January of each year to allow sufficient time for stakeholder input for each proposed revision.
  • Manufacturers must requalify and relist their systems each year, in line with the annual Technical Requirements revision schedule.
  • Grace Period Policy: A one-year listing grace period will be provided for systems that have been qualified under a previous version of the Technical Requirements but do not meet revised requirements. This grace period provides a period of one year for manufacturers to revise their current systems or offer a new system that qualifies according to the most current version of the Technical Requirements.

Delisting and Next Release

NLC Version 4.0 delisting:

Any NLC4 systems that have not been updated to NLC5 (that is, that do not have DLC-recognized cybersecurity) will be delisted on February 28, 2022. (This date has been extended from October 31, 2021 because of COVID-19-related complications in product development.) Before February 28, 2022, if a new system applies without cybersecurity or a listed system reapplies without cybersecurity, the system will be listed as NLC4 until proof of cybersecurity is submitted. When cybersecurity proof is accepted by the DLC, the listing version will be updated to match the application version most recently submitted for that system.

Application Timeline and Delisting:

The current plan for the timeline is shown below. The DLC has extended the validity timeframe of NLC5.

Annual renewal invoices are issued in July, due in 30 days.

NLC5 products will remain on the QPL provided that annual invoices are paid promptly.

Interior and Exterior Systems

The DLC will list interior and exterior control systems separately. It is recognized that some systems exist that function in both interior and exterior environments. For a single system to be qualified for both an interior AND an exterior listing, two applications must be submitted, one for the interior listing, and one for the exterior listing. A reduced fee is offered for the second listing.

The DLC offers reduced fee amounts for family member and private label systems. Family member systems are child or derivative systems of a parent system that may offer small differences in feature sets and/or characteristics, but are otherwise identical to the parent system. For complete definitions of family member systems and private label systems, see the System Definitions page. Manufacturers interested in preparing a family set of applications should contact info@designlights.org to confirm a plan before completing the applications.


Why Listing Fees?

Qualification and listing fees are required for review of system applications and updating of system information displayed on the QPL. These fees support the overall implementation and annual revision of the Networked Lighting Controls QPL. The DLC seeks significant energy savings for its Members and their customers through networked lighting control systems. Listing fees are leveraged with grant funding and additional funding provided by DLC Member utilities and energy efficiency programs to continually drive energy efficiency through the QPL and achieve widespread adoption of lighting control systems in the market.

Backed by financial incentives of DLC Member utilities, qualification on the QPL creates new opportunities for product differentiation and delivery of customer value. The DLC aims to support market expansion and to provide a single point of entry for manufacturers to participate in energy efficiency programs.
