Lighting Systems Initiative


The 2015 revision of the CEESM Commercial Lighting Systems Initiative expands the previous goal and strategic scope. It aims to improve the effectiveness of the marketplace in delivering energy efficient lighting practices in addition to energy efficient products. Modifying the scope is intended to align program designs with both mass-market strategies that promote efficient products, such as high volume replacement lamps, and with performance strategies to promote energy saving practices at the lighting system level.

The members of this CEE Initiative work to:

  • define and characterize lighting opportunities, approaches, and applications with high savings potential
  • define and establish performance metrics and capabilities to support these program approaches
  • compile, vet, and share information
  • develop CEE work products that lead to expanded implementation of these defined programs and metrics


The CEE Board’s decision to launch a revised, technology-neutral CEE Commercial Lighting Systems Initiative is intended to maintain Initiative relevance in the face of rapid innovation and rising codes and standards. CEE members finalized the new CEE Four Foot Linear T8 Replacement Lamp Specification and qualifying products list, which is designed to define efficiency performance metrics and distinguish high performance standards, while introducing a technology- neutral approach.

The mass-market opportunity remains large. 80% of all lamps in commercial buildings, or 2.2 billion, are linear fluorescent lamps. Of these, 1.6 billion are T12s. Representing 72% of the installed wattage in the commercial sector, linear fluorescent lighting continues to represent savings opportunity in commercial lighting energy. This graph demonstrates the market shift to more efficient fluorescent lighting products—T8s and T5s—that results in part from the efforts of efficiency program administrators.

The 2012 installed stock was approximately 700,000 LED linear luminaires and 400,000 LED replacement lamp systems. In 2014, the installed stock had grown to 9.8 million LED luminaires and 2.7 million LED lamp systems, demonstrating the rapid rate of change in the lighting market.

How to Participate

As with all CEE Initiatives, participation in the Commercial Lighting Systems Initiative is voluntary. To be considered an Initiative participant, an organization must support the CEE Commercial Lighting Systems Initiative through the following activities:

  • support the vision and goals of the Commercial Lighting Systems Initiative
  • incorporate at least one of the Initiative specifications in a regional or local educational or incentive program
  • communicate the scope, duration, and key aspects of the respective regional or local programs to CEE staff when requested
  • allow the use of the organization’s name and program information for the purpose of achieving the Initiative’s goals
