$50 Worth of LEDs May One Day Replace Your Basic 100-Watt Light Bulb. Soon.

Get ready to dump your power-hungry incandescent light bulbs and replace them with some LED-inspired lighting. The government phase-out of current 100-watt incandescent bulbs goes into effect January 2012 and, like it or not, LED may be the replacement.

Light bulb manufacturers are looking at LEDs because they're energy-efficient and easily mass produced. All it takes is a handful of these light-emitting diodes and some bright engineers to figure out how to cram them into a standard pear-shaped bulb. Progress comes with a price tag and these 100-watt LED bulbs may cost as much as $50 each when they first arrive. Don't panic as these prices will go down, eventually. [AP]
