Recently, Philips stands as the lonely first in the would-be line of contenders vying for the $10 million prize slated by the US government for offering an energy efficient alternative to the 60 Watt light bulb.
The idea of an XL prize money on developing a light bulb may seem absurd but the amount of energy it would help save, which comes to 34 Terawatt-hours of power nationwide per year, does validate the huge offering. The entries were supposed to deliver at least 900 Lumens output, with a consumption of less than 10 watts, and a lifespan of at least 25,000 hours.
Energy saving is good, we hope they also keep the cost economics of the 21st century lighting substitute in mind.
