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 CLTC is excited to announce a new publication in our Lighting Best Practices series, the Daylight Harvesting for Commercial Buildings Guide! This publication provides guidance towards meeting and exceeding California's Building Energy Efficiency Standards for daylight harvesting.
Interested in the current state of residential lighting products? CLTC recently presented on linear LED lamp technologies as part of a webinar panel focused on light sources for the residential market. The webinar was conducted in support of Bonneville Power Administration and can be revisited here.
Heading to the lighting aisle soon? Keep these key factors in mind when selecting your new light source:
The Million Lamp Challenge has officially been launched by the University of California system in consultation with the California State Department of General Services! The groups have issued their purchasing standards to encourage the purchase and installation of high-quality LED lamps in their buildings:
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.
