Introduction

Version 5.0 of the Solid-State Lighting (SSL) Technical Requirements is the first of two policy updates (V5.0 and V5.1) designed to improve the quality and controllability of high performance, energy efficient commercial lighting products by establishing requirements and reporting standards for DLC listed products. V5.0 lays the groundwork to capture and promote continuing advances in energy-efficient technology so that maximum energy savings and user satisfaction are possible. The requirements in this version are focused on efficacy and dimming, whereas V5.1 includes additional metrics around quality of light and controllability. The phased approach of V5.0 and V5.1 to incorporate quality of light metrics on the QPL will help ensure that high-quality products are listed, superior performing products can be differentiated, and additional energy savings are realized.

V5.0 applications will be accepted beginning on February 18, 2020. More information can be found in the V5.0 & V5.1 Manufacturer and Industry Guidance, published along with the V5.0 and V5.1 Technical Requirements.
