Field-Adjustable Optics/Distribution

Field-Adjustable Light Distribution

Field-adjustable lighting products are a relatively new trend in commercial lighting where performance characteristics such as light output, color temperature, and optics can be adjusted by the manufacturer, distributor, or contractor before or during installation. This allows manufacturers and distributors to capture greater economies of scale and stock fewer SKUs, reducing manufacturing and distribution costs while providing customers greater flexibility. As of Monday, March 26, 2018, the DLC published Testing and Reporting Requirements for Field-Adjustable Light Output Products and Color-Tunable Products. This new V4.4 DLC policy proposal is for products where the optics or light distribution of the fixture, lamp, or retrofit kit can be adjusted in the field.

The DLC has issued second draft Testing and Reporting Requirements that would enable high performance products with field-adjustable distribution capability to be qualified on the DLC SSL QPL. Please submit all comments using the DLC comment form to info@designlights.org by Monday, October 22, 2018. Scroll down to access the draft requirements documents.
