3-Foot, 8-Foot, and 2G11 Base Replacement Lamps

3-Foot TLEDs, 8-Foot TLEDs, and 2G11 Base Replacement Lamps

3-foot TLEDs, 8-foot TLEDs, and 2G11 Base Lamps are the next set of replacement lamps to be considered for eligibility on the DLC QPL. Including these lamps will facilitate incentive payments on high quality and energy efficient LED replacements in even more applications, such as 3- and 8-foot commercial strip fixtures and 2x2 luminaires designed for lamps with a 2G11 base, also known as PLL, Biax, or T5 twin-tube compact fluorescent lamps.

The DLC has issued second draft requirements that would allow these new form factors of LED replacement lamps to be qualified on the 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.

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.
