Field-Adjustable Light Output

Field-Adjustable Light Output


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. 

The DLC temporarily suspended the qualification of new field-adjustable light output products against the requirements published as a part of Technical Requirements V4.3 in order to revise the policy. An updated policy has been released as a part of Technical Requirements V4.4, and the DLC will resume qualification of field-adjustable light output products on October 18, 2018.
