Halving the cost of LEDs

Wall Street Journal : Bill Watkins, the former CEO of hard-disk drive maker Seagate Technology, wants to shake up the prices of solid-state light-emitting diodes.Watkins became CEO of LED maker Bridgelux in January. On Tuesday, the Sunnyvale, California, company released a product called Helieon that Mr. Watkins says will cost as low as $20 for a lighting unit that has a lifespan of more than 10 years.While $20 may seem like a lot for a lightbulb, Mr. Watkins says the price is less than half of the $50 that has been standard for similar LED lighting systems.
