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.
Generally, people expect two light sources with the same rated color appearance to appear identical when installed in their homes and businesses. Obvious variation often leads to dissatisfaction, complaints and product returns. To avoid these issues, it is important that light sources have sufficient chromatic consistency to ensure color matching for most people. Currently, the lighting industry relies on binning for correlated color temperature (CCT) and Duv to address this issue.
The California Lighting Technology Center, in collaboration with the California Energy Commission, is conducting research to develop and evaluate technology that integrates automated controls for heating, ventilating and air conditioning (HVAC), electric lighting and dynamic fenestration systems. The integrated system is referred to as the Integrated Building Control Retrofit Package (IBCRP), as it is aimed for retrofit projects in existing commercial buildings.
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.
