The Future of Lighting

The Future of Lighting

A new law is aimed at turning the lights out on Thomas Edison’s 131-year-old bulb that consumers have come to associate with the warm glow of home.

As of Jan. 1, the traditional 100-watt and 150-watt A19 incandescent light bulb is no longer sold in California. A year from now, the energy waster will be out of business nationwide.A built-in dock is attached to the battery and when Led light not in use folds up in a nice compact manner to about half the size of the iPhone itself.

In 2013, the familiar 75-watt incandescent also will be history. (California will shoo them off of store shelves one year earlier.) And in 2014, Americans will wave good-bye to their beloved—albeit energy-inefficient—60- and 40-watt A-shaped incandescents.

The resulting switch to more efficient compact fluorescent lamps (CFLs) or to the brand-new high-efficacy halogens that manufacturers have introduced in response to the “light bulb law” within the Energy Independence and Security Act of 2007 will mean considerably steeper prices—in the $2-per-bulb range—versus the 50-cent incandescent.Motorist Ian Beesley added: "It was running really well — they should led tube leave the lights switched off." But other than that, for many builders, the shift will barely register because—for now—only the bulbs, and "It has become almost a cliché to say that optical fibers are the cornerstone DSTT of the modern information age," said Badding. "These long, thin fibers, which are three times as thick as a human hair, can transmit more than a terabyte -- the equivalent of 250 DVDs -- of information per second. Still, there always are ways to improve on existing technology."not the fixtures, are required to change.County cabinet member for transport, Rodney Rose, said led downlight remodelling the junction was "pivotal" to tackling the city's congestion problems.

“It’s not that hard of a change to make for recessed lighting, which is most of the indoor lighting that we build into homes,Political assistant Rupert Dewey compact fluorescent crosses the junction on foot from the railway station to his office above The Jam Factory.” says Jim Bayless, owner of GreenBuilt Construction in Folsom, Calif.

In fact, estimates the National Electrical Manufacturers Association, about a quarter of the light bulbs sold in America are CFLs, and many pros long ago embraced them. Those who haven’t, advises Larry Weinstein, president of design/build firm DBS-Shared Solutions America in San Diego, should make the switch.

“Architects and contractors for the most part are hurting right now,” he reasons. “Those who are wise enough to realize there’s a substantial market in energy-efficient new homes are doing very well.”

Derek Greenauer, program manager for D&R International, a Silver Spring, Md.-based energy-efficiency consulting firm, agrees. “If builders can get up to speed on LEDs [light-emitting diodes] and technology and the new choices they’ll have for lighting homes, they can kind of ride that green wave to set a particular builder apart from competitors.”
