The technological advances transforming “Edison’s 130-year-old industry” promise to revolutionize the way light is integrated in our homes, workplaces, and cities.

As “the last industrial-age analog technology” is digitized, Felicity Barringer looks at “the fundamental rethinking of lighting now under way in research labs, executive offices and investor conferences.”

"Innovations on the horizon range from smart lampposts that can sense gas hazards to lights harnessed for office productivity or even to cure jet lag. Digital lighting based on light-emitting diodes — LEDs — offers the opportunity to flit beams delicately across stages like the San Francisco-Oakland Bay Bridge — creating a light sculpture more elegant than the garish marketers’ light shows on display in Times Square, Piccadilly Circus and the Shibuya district in Tokyo."

She explains other possible applications, such as lampposts that function as “nodes in a smart network that illuminate spaces, visually monitor them, sense heat and communicate with other nodes and human monitors.”

"James Highgate, an expert on the new technology who runs an annual LED industry conference, sees a transition period ahead ‘for the next three to five years, until the eight billion sockets in the U.S. get filled’ with LEDs. ‘Some people will never change,’ he added. ‘They’ll be in the alleys buying 100-watt incandescents.’”

Cheaper LED Bulbs Make It Easier to Switch Lights - NYTimes.com
LEDs last about 25 times as long as incandescents and three times as long as CFLs; we’re talking maybe 25,000 hours of light. Install one today, and you may not own your house, or even live, long enough to see it burn out. (Actually, LED bulbs generally don’t burn out at all; they just get dimmer.)
You know how hot incandescent bulbs become. That’s because they convert only 5 to 10 percent of your electricity into light; they waste the rest as heat. LED bulbs are far more efficient. They convert 60 percent of their electricity into light, so they consume far less electricity. You pay less, you pollute less.

 60-watt LED bulb to break $15 mark, Lighting Science says | CNET News
 Lighting Science Group and Dixon Technologies India today touted an LED light bulb equivalent to a 60-watt incandescent that they say will hit store shelves with a price below $15.

The omnidirectional LED bulb, in the traditional A19 shape of household incandescent light bulbs, will become available in India by the end of the year and worldwide, including in the U.S., early in 2012, the companies said. It’s the first in an expected series of products, including streetlights and industrial fixtures, that Lighting Science and Dixon plan to jointly manufacture and distribute.
Prices for LED bulbs meant to replace incandescents have been trending downward, but 60-watt equivalents typically have been priced at about $40 apiece. Advantages of LED bulbs include lower energy use and longer life.

Budget LEDs debut on Amazon
Lighting manufacturer Lighting Science Group announced yesterday it  will begin selling low-cost LED lightbulbs on Amazon.com beginning  today.
The company’s A19 omnidirectional 8.5-watt bulb (40-watt  equivalent) will sell for $21.98, and is only the first in a line of  low-budget LED bulbs planned for sale at the online superstore,  according to Lighting Science Group.
The company says its bulbs will last up to 23 years, and are 76 percent more efficient than a standard incandescent bulb.
"Lighting  accounts for more than 18 percent of the average U.S. household’s  energy bill—that’s because incandescent bulbs are essentially space  heaters that give off a little bit of light," Lighting Science Group CEO  Rich Weinberg said in a statement.
