Following a major technological shift from mercury vapor to metal halide in the past decade or so, high-intensity discharge (HID) product innovation is focused on this source type, specifically pulse-start systems.
Joel Spira, who founded Lutron Electronics Co. in 1961, invented the first solid-state dimmer in 1959. For decades after, dimmers were largely used to control the aesthetic environment. Only in recent years has dimming become an important part of the energy costs saving debate.
“The new and emerging energy market is creating quite a buzz among ECs at conferences like Lightfair International with LED lighting at the center of the conversation,” said Steven Witz, vice president, Continental Electrical Construction Co., Oak Brook, Ill.
With lighting and communications technology evolving rapidly, lighting manufacturers are under pressure to determine how to best reach out to and train busy electrical contractors (ECs) on new and existing products.
More than 8 billion lamps illuminate the United States, accounting for nearly 20 percent of all electricity consumption in the nation, according to a study released by the Department of Energy (DOE). The “2010 U.S.
The International Energy Conservation Code (IECC) is a model residential and commercial building energy code produced by the International Code Council, an organization dedicated to building safety and fire prevention.
Is it possible that some T5 lighting fixtures are perfectly efficient? One might get that idea based on some efficiency ratings of 98–100 percent, although it might not seem possible. Such a rating must be a mistake, right? But it’s not.
The ongoing quest for more efficient, greener power seems to touch on almost every aspect of modern life, including cars, home electricity, manufacturing and building construction. Even lighting has come under scrutiny. In that regard, a recent report by the U.S.
Lighting continues to be a huge chunk of a building’s annual energy costs—between 20 and 40 percent. While the need for light will never go away, analyzing its costs through energy modeling can help secure the installation of more efficient technologies.
Rebates and incentives offered by electric utilities and regional energy-efficiency organizations are currently enjoying a major upswing, providing a significant resource that can reduce the cost of investing in energy-efficient lighting.
As thousands of attendees gathered at the Lightfair International Conference in Las Vegas on May 10, 53 commercial light-emitting diode (LED) indoor lighting products were recognized and awarded in the fourth annual Next Generation Luminaires (NGL) solid-state lighting design competition.
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.
