Field-Adjustable Products

Field-Adjustable Products

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 has issued second draft requirements that would enable high quality, energy efficient field-adjustable products to be qualified and listed on DLC SSL Qualified Products List (QPL). The comment period is now closed.  Scroll down to access the second draft cover letter and draft requirements documents, as well as the first draft requirements for your reference.

DLC refinement of draft policy

Desired Outcomes and Benefits


New policy enables reliable and efficient field-adjustable lighting products to be qualified and listed on the DLC SSL QPL.


The policy inclues clear definition(s), performance criteria, and testing requirements to ensure listed products are high quality and energy efficient.

Energy efficiency program administrators and others support the installation of high quality, energy efficient field adjustable products in their lighting rebate or procurement programs.



Reduced manufacturing and distribution costs along with greater flexibility leads to greater market adoption of efficient lighting and increased customer satisfaction
