California Quality LED Lamp Specification

California Quality LED Lamp Specification

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.

CLASP Project: LED Replacement Lamp Testing

CLASP Project: LED Replacement Lamp Testing

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.

IES LD+A Research Matters: Studying chromaticity binning - what should we expect from today’s LED light sources?

08/15/2019

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.

Integrated Building Control Retrofit Package for Commercial Applications

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.

Million Lamp Challenge

Million Lamp Challenge

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: 

Educational Video Series: Lighting Controls Technologies & Requirements

Lighting Controls
08/10/2017

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.
