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.

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.
