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.
On June 10, the California Energy Commission unanimously approved building energy efficiency standards that will reduce energy costs and increase comfort in new and upgraded homes and other buildings.
The standards, which take effect on Jan. 1, 2017, focus on three key areas: updating residential requirements to move closer to California's zero net energy goals, updating nonresidential and high-rise residential requirements, and improving the clarity and consistency of existing regulations.
The retail sector, which represents 13 percent of California’s lighting electricity use, has historically not embraced the use of lighting controls to save energy. California regulators have responded to retailer’s concerns that lighting controls and lighting power density restrictions may have a negative impact on sales and customers. Currently, building lighting energy-efficiency standards for the retail sector are less stringent than regulations imposed on other commercial space types.

Exterior lighting for streets, roadways, parking lots, and other outside sites represents nearly 10% of the electricity consumed on military bases. Lighting in these areas typically consists of high pressure sodium or sometimes metal halide lamps that are normally controlled by photo-sensors located centrally or sometimes on each fixture. This limited functionality includes turning the lights on in the evening and off in the morning regardless of occupancy levels, thereby consuming more electricity than necessary.
The California Lighting Technology Center (CLTC) at the University of California, Davis announces the publication of five downloadable lighting design guides to help builders, contractors, and other lighting industry professionals meet or exceed California’s 2013 Building Energy Efficiency Standards (Title 24, Part 6).
Electrical Marketing—Smart building control and management system maker Daintree Networks, Los Altos, Calif., has formed an affiliate partnership with UC Davis' California Lighting Technology Center with the goal of advancing lighting controls. Daintree and CLTC will collaborate on efforts to raise awareness about the benefits of networked lighting controls.
