Reuters - Philips pioneers long-lasting LED streetlamps:
"AMSTERDAM (Reuters) - Philips has put up the first streetlamps that use light-emitting diodes (LEDs), which last four times longer than normal street lighting, the Dutch electronics group said on Friday. With 50,000 light hours, LED lamps do not have to be changed for 12 years when lit for an average 11 to 12 hours a day."
