In anticipation of a new law that will phase out incandescent light bulbs beginning next year, some shoppers are stockpiling large quantities of the bulbs for future use. According to USA Today, people aren't happy using the more energy-efficient compact fluorescent bulbs (CFLs), which are cheaper than LEDs and use 75-percent less energy than incandescents. Some complain that CFLs aren't quite as ...

Rather than carve a plain ol' jack-o'-lantern for Halloween, the guys at Hack A Day installed a 5-by-14 matrix of LEDs inside October's favorite squash. Like Kitt from 'Knight Rider,' the pumpkin flashes a series of disco-like patterns, along with the seasonally obvious greeting "HAPPY HALLOWEEN." The project took eight hours of soldering and required more than 70 holes to be drilled, commanding ...

Share "Most of these works -- if you pause them -- you can't tell what you're looking at," says artist Jim Campbell, as his newest installation flickers in the background. 'Scattered Light' is a 50-foot-long array on an 80-foot wide, 16-foot-high and 16-foot-deep structure supporting over 1,600 lightbulbs fitted with LEDs, which are programmed to display a low-resolution, moving image as ...

Your hybrid car should help reduce your carbon footprint, but what about all the energy you waste when you come home and turn on the lights? Apparently, GE's new hybrid lightbulb can help control your energy usage, without sacrificing your late-night lighting. As Engadget explains, GE's forthcoming product is essentially two lightbulbs in one. At first glance, it looks like any other compact ...

Have you ever wondered exactly how "healthy" a light bulb is for your energy bill? If so, the Federal Trade Commission (FTC) is here to help. According to an FTC press release, every light bulb manufactured after the halfway-point of 2011 will feature a "Lighting Facts" label on its packaging. This label, which is a clear nod to the Nutrition Facts label on food products, will provide information ...

A new solar light bulb could be a safer and more affordable lighting option for people who live in developing nations. According to CNET News, the Nokero N100 solar LED bulb can provide up to four hours of light on a single charge -- making it the world's first solar-powered light bulb. The N100 is about the size of your average incandescent bulb, but the green plastic housing holds four solar ...

In our ongoing look at Tech Art History, we've been examining how technology has revolutionized the ways in which we both create and consume art. And, as we've seen, technology, among other things, has blurred the once impermeable divisions between artist and observer, and between the commercial and the artistic. It's a continuously fluid and evolving paradigm that German researcher Johannes ...

The iPad could be causing restless nights for many who use it to read e-books before lights out. According to the Los Angeles Times, the light that's emitted from the iPad's screen inhibits the release of melatonin, a chemical that tells your body to wind down for the evening. This holds true for any device that emits unnatural light -- be it a TV or a cell phone. But Frisca Yan-Go, director of ...

Hyperspectral imaging might sound like a fanciful process dreamed up by the creator of a crappy sci-fi film, but it is, in fact, a very real and surprisingly simple technology that analyzes light from across the spectrum. Using ultraviolet and infrared rays, scientists have found that specialized cameras can actually help locate unmarked graves, and could potentially aid missing persons ...

On Thursday, General Electric (GE) revealed a new LED light bulb that could replace every incandescent 40-watt bulb in your house. According to CNET News, the Energy Smart LED bulb emits about 450 lumens, which is equal to the output of your average 40-watt bulb, but consumes only nine watts of power. If you used it for an average of four hours each day, the bulb could last 17 years. "This is a ...

In what we can only imagine is an effort to make somebody (please, anybody!) care about the 2010 Vancouver Winter Olympic Games, visitors to the event will be able to participate in a long-distance, mind-control light show that will take place at Niagara Falls. Don't shrug those shoulders; it's more interesting than watching Olympic curling. According to Gizmodo, the exhibit dubbed "The Bright ...

For most of us, getting "twisted" isn't all that complicated. But for a group of scientists, who play with beams of light and not bottles of Henny, an otherwise simple, two-step process can get very complex, indeed. As LiveScience reports, physicists at the University of Bristol in England have found a way to turn beams of light into pretzel-shaped knots, an achievement that's apparently ...

Hold onto those wands, all you would-be wizards. One of Harry Potter's most valuable possessions might soon make the jump from the page to the real world. According to The Daily Mail, researchers at Imperial College in London received an $8.1-million grant to develop an invisibility suit. That's right, you could throw on a garment and sneak around, just like Harry did while stalking the halls of ...

While this lamp is hot pink and looks like a computer mouse with some kind of mutant growth sticking out of its back, it will cost you literally nothing to run. This monstrosity has eight LEDs that provide light to read by, and rather than jacking up your electricity bill, it runs on power siphoned from your local telco. You see, rather than plugging into a standard power outlet, this lamp has ...

Flash photography lets us, among other things, take pictures in dimly lit situations. Unfortunately, when taking pictures of people, it often leads to the dreaded red eye and/or the deer-in-headlights effect, with blown out highlights and harsh shadows. The light itself can also be distracting, hence its exile from many museums, concerts, and public performances. But if NYU student Dilip Krishnan ...
