DLC Releases Final NLC5.1 Technical Requirements

DLC Releases Final NLC5.1 Technical Requirements

The Design Lights Consortium (DLC) has released their final version of v5.1 Networked Lighting Control technical requirements (NLC5.1). NLC5.1 is a minor revision that contains updates to the policy’s energy monitoring and cybersecurity requirements. There will not be a delisting associated with the policy. Existing listed v5.0 NLC will continue to be DLC listed.

Cybersecurity Updates:

  • Now accepts PSA-certified chip level 1
  • Includes updated criteria for acceptance

Other Updates:

  • A new section clarifies Primary Use Designations, such as “Whole Building” and “Portfolio”.
  • The “Requirements Other Than Control Capabilities” section is now formatted as Table 0, rather than as text.
  • The words “Interior” and “Exterior” were changed to “Indoor” and “Outdoor” to align with other DLC documents.

The Final NLC5.1 Technical Requirements can be found here.
