Desired Outcomes and Benefits


New product application types enable additional reliable replacement LED lighting products to be qualified and listed on the DLC’s SSL QPL. 


The new application types include 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 a greater variety of high quality, energy efficient replacement products in their lighting rebate or procurement programs.



DLC listing of 3-foot, 8-foot, and 2G11 base lamps in combination with utility rebates leads to higher market adoption and increased customer satisfaction.
