Performance Testing Report: Omni-directional LED Replacement Lamps

08/07/2014

A number of lighting manufacturers now produce LED replacement lamps for traditional 60W incandescent lamps, and stakeholders at the state and national levels face decisions regarding quality standards for this product category. To assist these stakeholders and assess the current state of this segment of the lighting market, CLTC performed photometric and electrical tests on samples of 26 commercially available A19 and A21 omnidirectional LED replacement products.

LED Lamp Project Lights the Way to Flicker-Free Replacement

Jade Sky Technologies (“JST”) collaborated with UC Davis's California Lighting Technology Center (CLTC) on a project designed to further the development of replacement lamps that meet the Voluntary California Quality LED Lamp Specification. Lab testing and characterization at CLTC showed that lamps incorporating JST's driver architecture met, or exceeded, the California Quality specification, using cost-effective and easily accessible components.

Since its establishment in 2003, the California Lighting Technology Center (CLTC) at UC Davis has conducted extended photometric and electrical testing of light sources. During the last 18 years, CLTC has been successful in establishing an array of testing facilities, some with unique capabilities, including complete photometric and electrical testing laboratories, and chambers for lifecycle testing under customized operational conditions.

This working paper, co-written by CLTC Directors Michael Siminovitch and Konstantinos Papamichael, urges manufacturers, regulators and utilities that offer product incentives to consider quality and consumer satisfaction first when it comes to LED products. Their arguments in favor of lighting quality, over efficiency, were also presented in "Trading Up," an article published in the August 2011 issue of LD+A.

Choosing the Right Light: Light buying guidelines from UC Davis Professor Michael Siminovitch

02/01/2013

A growing number of LED products are entering the market, adding to the many choices consumers already face. By 2025, 60 percent of residential lighting across the U.S. will likely be LED-based. While nearly all LED lighting choices offer energy savings, not all LED products are created equal, and LEDs may not always be the best type of lamp to use. Professor Michael Siminovitch, director of the California Lighting Technology Center at UC Davis, urges people to consider five things when looking for the right light.

Directional LED Lamps – Laboratory Testing Program

12/01/2012

The retail sector constitutes one of the largest energy consumers in the U.S., and halogen parabolic aluminized reflector (PAR) and multifaceted reflector (MR) lamps are common retail lighting choices. LED replacement lamps have the potential to transform lighting energy use in this sector, and manufacturers of LED PAR and MR lamps now claim comparable photometric performance, as well  as much greater longevity, than traditional halogen lamps.

CPUC Support

CLTC communicates and collaborates with the Energy Division of the California Public Utilities Commission (CPUC) to provide objective information and expert analysis that may inform the Commission’s lighting-related energy policies, programs and mandates. CLTC supports the CPUC’s Energy Division in its lighting-related goals, initiatives and activities, including the Lighting Action Plan, a near-term implementation guide for achieving the goals stated in the Lighting Chapter of California’s Long-Term Energy Efficiency Strategic Plan.
