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.
