Incredibly long life span and energy efficient - LED light bulbs are set to
brighten up your life

Who would have guessed that the once humble light bulb would become a 21st
Century technological wonder? The Luxeon LED family of light bulbs from
Philips now lasts 100 times longer, and is up to 4 times brighter than
today's standard incandescent bulbs. Not only this but we have managed to
break through a major technological barrier - recreating white light through
the power of the Light Emitting Diode.
