CLTC collaborated with the Emerging Technologies group at the Pacific Gas & Electric Company to evaluate linear LED lamps in a variety of fixture applications as well as identify any interoperability issues.
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.
In 2013 the SPEED team collaborated with UC San Francisco to demonstrate three lighting retrofits of fluorescent fixtures. Three control systems, each with different system architectures, were installed in three different UCSF corridors. All three systems utilize occupancy controls, but each one provides a different level of control, different programming capabilities, and energy and maintenance monitoring features. The demonstrations produced energy savings of 53–68%, based on occupancy rates of 12–16%.
Fluorescent lamps currently constitute 80 percent of lamps installed in the U.S. commercial sector, according to the Department of Energy's latest Lighting Market Characterization report. LED lighting products are receiving a great deal of attention for their potential to replace fluorescent lighting, reduce energy use and improve lighting quality in a variety of indoor commercial applications, including offices, classrooms and retail stores.
Linear fluorescent lamps account for 83 percent of installed lamps in the California commercial sector per a lighting market characterization performed in 2014. LED lighting products are receiving attention for their potential to replace fluorescent lighting, reduce energy use and improve lighting quality in a variety of indoor commercial applications, including offices, classrooms and retail stores. LED alternatives to linear fluorescent lighting products fall into three main categories: linear retrofit lamp solutions, linear retrofits for troffers and dedicated luminaires.
These presentation slides cover best practices for residential lighting design. The material is designed to help builders meet, or exceed, California's 2008 Title 24 Building Energy Efficiency Standards. It includes background and policy, common lighting terms and technology updates, guidance in residential lighting design, a step-by-step overview of the Title 24 compliance process, and additional resources.
CLTC at UC Davis is on a mission to get energy-efficient lighting into offices and homes.
CLTC Director Michael Siminovitch discusses improvements in fluorescent lighting.
Michael Siminovitch, director of the California Lighting Technology Center, maps the history of fluorescent lighting. In its original use as an art form, fluorescents were "quite beautiful, quite ornate and they were decoration light sources."
Adaptive exterior lighting products are entering the marketplace at a rapid rate. By coupling features such as occupancy-based lighting controls with efficacious, dimmable sources, these solutions offer 30 – 75% energy savings over traditional systems.
