The California Energy Commission has adopted a voluntary lighting quality specification for LED replacement lamps. The new standard requires LED lamps to meet certain performance criteria in order to qualify for incentive programs and rebates. These criteria include the color of a lamp’s light, its consistency over time, and its accuracy in rendering colors. The specification for incentivized LED lamps also includes requirements regarding dimming and flickering.
The Collaborative Labeling and Appliance Standards Program (CLASP), an international nonprofit, partnered with CLTC to conduct laboratory testing of LED lamps currently available in the U.S. market. Data collected and analyzed in the course of testing helped the California Energy Commission develop a voluntary quality-based performance specification for screw-base LED lamps, with requirements for color characteristics and dimmability. CLASP and CLTC are also assisting the Energy Commission in developing a test methodology for measuring these quality characteristics.
The California Lighting Technology Center (CLTC) at the University of California Davis collaborated with the California Energy Commission to provide this educational video series in support of the 2016 Building Energy Efficiency Standards (Title 24). Sensors and controls can achieve significant energy savings by automatically adjusting lighting based on time of day, available task needs, daylight, occupancy, and electricity supply or cost.
Lighting projects that involve updating CFL lighting systems should consider all viable retrofit options. When retrofitting between CFL four-pin lamps and LED solutions, it is important to observe safety precautions and consider performance variables.
Widespread adoption of LED lighting for general illumination applications is poised to be the single, largest advancement in lighting efficiency during the 21st century. Due to its potential, a variety of market actors have introduced LED products and made associated performance claims that have set the technology up with somewhat unrealistic expectations regarding system efficacy and longevity. To compete in this market, LED manufacturers have focused on research to improve efficacy and reduce product costs, often at the expense of product quality and feature optimization.

The 2015 Lighting Technology Overview (LTO) provides overviews of commercial and residential lighting technologies and strategies with the potential to significantly reduce California’s lighting energy use. The guide includes information on expected energy savings, factors to consider when comparing products, sample products, and case studies for indoor and outdoor lighting and controls technologies. Products in the guide include:
The potential to reduce energy consumption in existing and commercial buildings is enormous. On average, 30% of the energy used in commercial buildings is wasted, according to the U.S. Environmental Protection Agency. Lighting has a large potential for energy savings for any U.S. building end use, with a significant fraction of that potential coming from lighting controls.
CLTC, in partnership with Southern California Edison, recently kicked off a new project portfolio to assess controls, lighting, and daylighting technologies and their potential for commercial applications. The new projects will have elements of market assessment, EM&V, and selected demonstrations.
The project focus is on evaluating the following technologies:
