Phase Two of DesignLights Consortium’s Final Performance Standards for Commercial LED Lighting Takes Effect July 1, 2020

July 6, 2020
Solid-State Lighting Technical Requirements V5.1 will improve the quality and controllability of high performance, energy efficient commercial lighting products.

MEDFORD, MA – July 1, 2020 –The DesignLights Consortium (DLC) today began accepting products under new performance standards for high-performing solid-state commercial lighting that will maximize energy savings and user benefits of commercial LEDs by capturing advances in lighting quality and control functionality of installed products.

Solid-State Lighting Technical Requirements V5.1 is designed to improve the quality of DLC listed products. The DLC established requirements and reporting standards for characteristics such as color performance and discomfort glare based on light distribution. The new policy also ensures that products listed on the QPL have the capability to be dimmed, should customers wish to take advantage of dimming. Since LEDs installed now may run for a decade or more, strengthening controllability requirements such as dimming at the time of installation locks in potential energy and cost savings for years to come.

“Adding these performance standards not only boosts the quality of products listed on the DLC’s Qualified Products List, but provides product performance data that enables users to better distinguish characteristics needed for different installations,” DLC Executive Director and CEO Christina Halfpenny said. “Our new requirements will promote better quality of light for people in the built environment, while supporting additional energy savings.”

The DLC’s SSL QPL supports energy efficiency incentive programs for commercial and industrial electric utility customers across the US and Canada by providing objective, third-party evaluation of product performance. Resources that explain new the new metrics, benefits to customers and trade allies, and timelines for transitioning to the new requirements are available to utility energy efficiency programs.

The DLC is also providing manufacturer and industry guidance materials to ease the transition to V5.1

QPL applications under V5.1 of the SSL Technical Requirements will be accepted beginning today.  A detailed timeline is posted on the DLC’s website.
