Horticultural Lighting Listing Fees

The DLC application fee covers the costs of application review, as well as in developing, creating, and hosting the informational infrastructure of the Horticultural QPL. The specific fee amount is dependent on the particular characteristics of the horticultural fixture, as described in the price tables below. Please review the Technical Requirements page to clarify any policy requirements, and contact horticulture@designlights.org with any questions about submitting an application.

Expedited Application Fees

The DLC is offering a limited time option to expedite your horticultural application review. Learn more about expediting your application here. Expedited applications are held to the same requirements as non-expedited applications.

Expedited Application
Expedited application fee$1650 per application

The expedite fee is due at the time of typical application invoicing, and is paid in addition to the regular fees associated with your application. Once an application is submitted as expedited, the application will be processed as expedited through to completion. Failure to pay the invoice with the expedite fee will result in appropriate consequences, including, but not limited to, placing application on hold.

Notes:

The DLC reserves the right to extend any application review timeframe due to holidays and application volume spikes. These extensions will be communicated via the DLC website and the Application Portal.

Closed, canceled, or rejected applications cannot not be reopened – instead, a new application must be created. To avoid having to create a new application, please either provide missing information or documentation within 10 business days of being notified of application issues, or provide an estimated time-frame for submitting the missing information or documentation within 10 business days of being notified of issues.
