By 2012, over 40 percent of the 80,000 streetlights in Detroit were not functioning, leaving the troubled city mired in darkness. To compound the problem, much of the grid relied on a series of outdated circuits—if one transformer went out, every light in the series went dark.
Flush with the resources needed to execute his vision, Jones’s team has outpaced expectations—the Authority is well over halfway to its goal of relighting the entire city, and has replaced more than 42,000 lights. Localized engineering studies have given the team the resources to discourage copper theft by switching to aluminum wiring, and the PLA is moving away from the faulty series circuit system. The new bulbs being installed are 150-watt equivalent LEDs—more energy efficient and two times brighter than the archaic high-pressure sodium bulbs they replace.
Lighting, like everything else, has gone digital. Instead of creating light with wires and gas inside a hot enclosure, we now use semiconductors known as light-emitting diodes, or LEDs. Diminutive and durable, they’re a far cry from Edison’s incandescents—and they’re enabling a lot of competition. Soraa, a lighting company founded in 2008 by Nobel Prize in physics winner Shuji Nakamura, sells commercial lights to California Pizza Kitchen and Starwood Hotels. Ketra, a six-year-old startup, provides lighting for the Art Institute of Chicago and Tiffany & Co
The rapid shift has the incumbents scrambling. In March, Philips announced plans to sell its LED component-making division. Siemens spun out Osram through an initial public offering. Rumors suggest that GE’s lighting division could be for sale. (The company denies it.) “The rapid transition to LEDs has caught the major manufacturers a bit unawares,” says Will Rhodes, a market researcher at IHS Technology. “Their traditional business is falling faster than their LED business is taking off.”
Leave it to Disney and its technologies to make you part of the show – even when you are far from their parks
At a mall
Love the bit where the guy says on his phone "I think I am being shadowed by Goofy". How did person at other end react?
Also geeks, sure you know what Umbra and Penumbra are?
By making you part of a show
Mickey hats with LEDs allow audiences to Glow with the Show. BTW there is also a Minnie Mouse-inspired headband, a Mickey Mouse glove and, my favorite, a magical wand that reminds me of Sorcerer Mickey.

As for the spire, it contains about 1,500 LEDs of its own—which could allow for a breathtaking light show. “We can define any hue or brightness level,” says Mark Domino, the digital-media artist behind the building’s illuminations. “There’s an RGB value charged to each light that can be controlled independently.” The result is millions of potential color combinations and even animation (building operator Durst Organization is developing a control system). Domino has real-time control over the lighting program via his phone, though he says he doesn’t know whether management will let him use this custom-built software when 1WTC opens later this year.
University of Florida researchers say they can alter the levels of antioxidants and other healthy compounds in sprouts, including kale. They are employing a technology found everywhere from traffic signals to computer power buttons: light-emitting diodes (LEDs).
LEDs are small, cool and energy efficient. They also produce light from narrow bands within the spectrum, making it easy to give plants a focused dose of, say, red light. This functionality is important because scientists have known for some time that a plant’s chemical processes can alter depending on the wavelength of light to which it is exposed. Studies have shown sweeping metabolic changes occur in plants when they are grown under different qualities of the light, including some humans cannot see.
It was only a matter of time before Walmart would try to take command of the LED light bulb market by drastically undercutting the competition. That's now happened; the massive retailer has unveiled a new line of LED bulbs under its in-house Great Value brand. The light bulbs, immediately available from all US stores and soon at Walmart.com, start at under $9 — priced even lower than Cree's $13 breakthrough bulb. Walmart isn't new to selling LED light bulbs, but this is its most aggressive push yet to make them affordable for shoppers. In all, the Great Value line includes 26 different bulb types, the cheapest of which costs only $8.88.

“On Feb. 7, Deepak Chopra showed up at the Silicon Valley offices of German software giant SAP (SAP), causing quite a stir. Hundreds of people packed SAP’s cafeteria and an overflow room to listen to the New Age guru. Chopra, wearing a black suit with red sneakers, advised workers to sleep more, eat right, and meditate on their place in the world. And, if anyone needed help, Chopra recommended his line of consciousness-altering Dream Weaver glasses. “I got the idea for these during my first LSD experience at the age of 17,” Chopra told the SAP employees.”
That would have been in 1963, btw.
Whether you believe Chopra is such a far looking technology visionary, or needs hallucinogenics (btw he clarified on Conan his LSD use was during medical school) his device uses light and sound pulses at specified frequencies. “Behind your closed eyelids you will see a complex kaleidoscope of color, multidimensional layers of fractals and a variety of dream-like imagery”
It is supposed to help the user relax and reach trances states as in “Gregorian chanting, Hebrew davening, Tibetan prayer bowls, Native American drum circles and rain chants, Sufi chants and Whirling dervishes, and African trance dancing.”
That may be too “far out” for many users but here is Chopra describing the product
