Pacific Gas and Electric Company— California K-12 school districts are in the process of updating and retrofitting the mechanical and engineering systems in their schools, primarily through the implementation of Proposition 39. Improving the efficiency of school lighting is a priority in the effort to increase the energy efficiency of school facilities, due to its relative simplicity in comparison to retrofitting complex mechanical systems.
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.
Due to the increased availability and cost-effectiveness of LED multifaceted reflector (MR) lamps, residential and commercial users are looking to these products for an energy-efficient alternative to traditional, halogen MR sources.
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.

In today’s world, people spend much of their time indoors. Be it at home or at work, out shopping or in a restaurant – the light that surrounds us affects our mood and every aspect of our daily experience. In interior spaces, the lighting has to be flexible and highly customizable to accommodate for changes in the time of day, the seasons and on-site activities.
UC Davis Today—In most classes, coursework involves sitting in front of a computer. But UC Davis students in professor Michael Siminovitch’s Design with Light class are hard at play. They’re using their hands and their imaginations to devise what could become the next big thing in lighting. Read the full story.
The California Lighting Technology Center’s Lighting for Office Applications Guide is designed to familiarize builders and lighting industry professionals with the office nonresidential portion of California’s 2013 Building Energy Efficiency Standards (Title 24, Part 6).
The guide includes the compliance process and requirements, current lighting technologies, and recommendations for implementing the standards in new construction or renovation projects. It serves as a resource for those involved in constructing, maintaining, or retrofitting California's office buildings.
