The DLC offices will be closed from December 25th, 2024 through January 1st, 2025.  We do not anticipate any delays in application processing from this closure.  Please email info@designlights.org with any questions.

Due to the continuing disruption to operations for both our members and stakeholders as a result of COVID-19, the DLC is extending the delisting date for products qualified under SSL Technical Requirements V4.4 by two months. The new dates are:

  • January 31, 2021: Deadline to update V4.4 listed products to V5.0 or V51.
  • February 28, 2021: Delisting date for V4.4 listed productsthat have not been updated.

Please review the Manufacturer and Industry Guidance for additional details about the delisting extension. The updated delisting timeline is also summarized below.

The DLC remains dedicated to our mission to enable energy optimization through quality and connected solutions for people and the environment. As a consortium, we also recognize that our success is collective and that this year has presented unprecedented challenges for the lighting industry. We are committed to work with our stakeholders to balance future needs with current realities. If you have questions about the changes to the SSL Technical Requirements, please email us at info@designlights.org.
