Cheaper LED Lightbulbs Are on the Way

Cost has been a major barrier in keeping people from buying energy-efficient LED lightbulbs. While they last much longer than $1 incandescent bulbs or $4 compact fluorescents, their sticker-price is daunting: a 60-watt equivalent LED bulb costs $15 to $25. Now one of the world's largest LED makers, Osram Opto Semiconductors, says it has perfected a technique that could significantly cut the production cost of LEDs.
