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.
This work will discuss the CALCTP program, its energy savings potential, the challenges in educating an established trade group in new technology, programs stemming from the initial CALCTP effort, and the immediate need for ongoing support to ensure this model program continues to succeed in the coming years. Presented by Cori Jackson at the American Council for an Energy-Efficient Economy (ACEEE) Conference 2012.
Street lights with controls systems offer dynamic dimming during long periods of inactivity, a feature with tremendous potential to save energy, mitigate waste, reduce light pollution, and increase public safety. In spite of all these advantages, there is no nationwide control standard established to date, and LED street lights are being installed en masse without this important feature. These fixtures are likely to be in use for as long as 20 years, so the fixed-wattage, un-retrofittable fixtures sold today represent a significant loss in long-term savings opportunity.
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.
Lighting accounts for about a quarter of California’s electricity use, and installing energy-efficient lighting can lead to significant energy, maintenance, carbon, and economic savings, according to the California Public Utilities Commission (CPUC). In September 2010, the CPUC adopted a plan to achieve a 60–80% reduction in statewide electrical lighting consumption by 2020.
Demonstrations on UC and CSU campuses have proven that SPEED technologies offer reliable, cost-effective solutions for achieving deep energy savings. Effective July 1, 2014, many SPEED technologies will be required under California’s 2013 Title 24 Building Energy Efficiency Standards.
Lighting accounts for approximately 25 percent of California’s energy use, making energy-efficient lighting technologies a vital part of the state’s strategy for meeting its legislated climate goals. The Lighting Action Plan details the lighting portion of the California Energy Efficiency Strategic Plan, a comprehensive roadmap outlining solutions for reducing California’s energy consumption.
Pacific Gas and Electric Company (PG&E) partnered with the California Lighting Technology Center (CLTC) at the University of California, Davis, to assess how education or incentive programs for lighting that uses light-emitting diode (LED) technology might best serve retail business owners within PG&E’s service territory. LED replacement lamps provide a solution for business and building owners looking to increase the energy efficiency of their lighting systems in order to meet, or exceed, 2013 Title 24 standards.
This project examined energy end-uses in the residential, commercial, and in some cases the industrial sectors. The analysis attempts to consolidate, in one document, the energy savings potential and design characteristics of best-on-market products, best-engineered products, and emerging technologies in research & development.
