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.

What’s New in CLTC’s Project Portfolio

Energy-Efficient Lighting System Evaluations for Commercial Applications

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.

Energy Use Reporting through Lighting Control Systems

Energy Use Reporting through Lighting Control Systems

One of the features of networked lighting controls is the ability to monitor lighting energy use over time and adjust the system to achieve the best possible performance. Facility managers can match system use to expectations and adjust system settings to result in optimized user comfort while maximizing savings. Real-time energy monitoring offered by some control systems has also piqued the interest of utility program managers in locations in the U.S. where rebates assist with the accelerated adoption of emerging technologies.

Energy-Efficient Lighting Systems Evaluations for Commercial Applications

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:

Advanced Lighting Control Systems

Advanced lighting control systems (ALCS) provide networked control and monitoring capabilities of connected luminaires via onboard metering and system reporting features. These advanced features allow system owners to dynamically balance visual comfort and lighting energy use. CLTC, in collaboration with SDG&E, developed a technology validation program to determine the accuracy and reliability of onboard metering and system reporting features of advanced lighting control systems.

MR-16 LED Replacement Lamps: Electrical Compatibility and Performance

05/01/2015

As light emitting diode (LED) MR16 lamps become more prevalent in the commercial market, both residential and commercial end‐users are considering these lamps as replacements for currently installed halogen incandescent MR16 sources. While the energy savings associated with LED lamp replacements is evident, the compatibility of LED MR16 lamps with existing electrical hardware is not. In one‐to‐one lamp retrofits, MR16 LED lamps often demonstrate negative performance characteristics such as visible flicker and audible humming.

Searching for the Link between Light at Night and Health
