On Nov. 14, 2011, the Department of Energy (DOE) announced new fluorescent lamp ballast efficiency standards that take effect Nov. 14, 2014, and affect seven product classes. These regulations cover T8, T5 and T12 ballasts, including ballasts designed for nonresidential and previously exempted residential use. They also cover previously exempted outdoor sign and T12 dimming ballasts. READ MORE

On July 14, 2012, Department of Energy (DOE) standards covering many popular incandescent reflector lamps will take effect, eliminating a majority of lamps from the market in favor of more efficient, higher cost alternatives. READ MORE

Stairwell lighting is typically operated continuously at full output in nonresidential buildings even though these spaces are only intermittently used. In recent years, lighting manufacturers have begun offering a solution that can reduce energy costs while providing satisfactory levels of illumination for emergency egress. These lighting fixtures adjust light levels based on occupancy. READ MORE

By Oct. 18, 2013, all states in the United States must put in place a commercial building energy code at least as stringent as the ASHRAE/IES 90.1 2010 energy standard, according to a Department of Energy (DOE) ruling on Oct. 19, 2011. READ MORE

While experimenting with high-frequency current, inventor Nikola Tesla developed an electrodeless lamp, but the concept remained largely unexplored for the next century (except as a novelty lamp in the 1980s). The first practical electrodeless lamp appeared a short time later, and the technology continues to gain in popularity today due to its energy and maintenance advantages. READ MORE

By now, the electrical industry is well aware that national energy standards have eliminated the manufacture and import of fluorescent magnetic ballasts for 4- and 8-foot standard and energy-saving T12 lamps, with few exceptions. On July 14, 2012, Department of Energy (DOE) rules regulating general-service fluorescent lamps will go into effect, eliminating many popular models. READ MORE

Common household lamps (light bulbs) now carry uniform labeling to facilitate educated decisions focusing on light output and energy costs, not watts, helping consumers transition to more efficient lamp types. People typically purchase traditional incandescent lamps based on wattage. READ MORE
December 2011
Energy codes, green building projects, user interest in flexibility and other market forces are driving demand for lighting solutions, including high-intensity discharge (HID) lighting systems, such as high-pressure sodium and metal halide. HID lamps may be dimmed using either step or continuous dimming. READ MORE
