DLC Logo Violations

DLC Logo Violation notices are intended to provide utility energy efficiency programs and other specifiers with confirmation that a product in question is using the logo or trademark without permission, and the performance has NOT been evaluated by the DLC. Read more about use of the DLC logos by clicking the green button. The DLC Qualified Products Lists (“QPLs”) are the only source to validate that a product has been evaluated by the DLC and ensure that it meets the DLC requirements and thresholds for performance. 

The DLC Logos and Trademarks are a valuable asset to the DLC, its members, and product manufacturers who have products listed on the DLC QPL. Ensuring that the DLC Logos and Trademarks are properly used protects every DLC stakeholder’s investment in the program - and consumer confidence in the DLC brand. Unauthorized and/or improper use of the DLC Logos and Trademarks causes confusion among consumers, which compromises the DLC brand and its reputation. It may also constitute trademark infringement, trademark dilution, false advertising, fraud and/or other violations of law.

Logo Violation Notices will be posted on this page with the date, information about the company, and product(s) that have violated the DLC’s Logo and Trademark Guidelines. All logo violations will meet one of the following criteria:

     - The manufacturer does not have a DLC account, or
     - The manufacturer has not listed any products within the last 12 months, or
     - The manufacturer has not responded to previous email notifications.

When the DLC has confirmed that all issues have been resolved, the Logo Violation Notice will be marked as “Resolved” and will be archived in an aggregated list on the Logo Violation Notice archive web page. This aggregated list is updated monthly.

What constitutes a logo violation notice?

    - Unauthorized use of the DLC Logos or Trademarks for products that have not been evaluated by the DLC and are not listed on the DLC QPLs.
    - Misuse of any DLC logo or reference to DLC qualification in marketing communications and materials that are not in compliance with Logo and Trademark Guidelines.

Please see the full Logo and Trademark Guidelines for more detail.  

The DLC actively monitors the use of the DLC Logos and Trademarks, and requests the assistance of its stakeholders to help police its brand. Please use the form below to report a trademark violation. To ask for a review of materials, please contact info@designlights.org.
