"It's hard to stare at a computer monitor for hours after dark, with the rest of the lights turned off in your home or office. Still, this is how many of us play games, myself included. When Antec offered to send the soundscience halo 6 LED bias lighting kit—which is a long official name—I had nothing to lose. If it didn't work, I could write a short, snarky post dismissing it as hokum. If it did work, my eyes would be more comfortable.

"If you thought mousetraps were tough, try building a better lightbulb. Just in time for Earth Day, a team of American inventors have created a bizarre-looking new bulb that turns illumination on its ear, using light-emitting diodes (LEDs) clustered within a conventionally shaped bulb for illumination rather than filaments or fluorescent tubes. It will never end up in a landfill. It will not poison anybody. It may be the light of the future, hopes Switch Lighting CFO Brett Sharenow.

"The latest thing in Japanese orthodontistry involves putting LEDs into braces. Actually, no, but hip young Japanese kids can have their teeth outfitted with LEDs to light up their smiles like a Christmas tree."

"The one that's closest to being here today is a new LED lightbulb that features lighting technology created by Cree, and produces 450 lumens from a power draw of just 7 watts. It'll retail for $25 and be sold door-to-door through Kamen's FIRST youth program." | more

Quantum computers scarcely exist yet, but scientists have already begun working on shrinking them down by creating smaller components. A group of researchers have devised a way to use an LED to generate the entangled photon pairs needed for quantum teleportation, computing, and encryption. While the LED is not quite as reliable as lasers, its smaller footprint should help make quantum applications a bit more practical.

According to recent news from market sources in the LCD display manufacturing industry, the transition to LED-backlit monitors has been growing at a positively increasing rate, and the global market is on track to see the technology becoming mainstream in the consumer sector this year in 2010.

Does the latest generation of energy-saving light bulbs save energy? A comprehensive study conducted by Osram, the German lighting company, provides evidence that they do.

While that may seem self-evident, until the release of the report on Monday the answer remained unclear.
