The answer lies in the technology
of compact fluorescent lamps. Regular bulbs heat
a filament, which over time eventually burns out.
(Usually around 1000 hours) Smartlights operate
on the same principal as fluorescent lamps that
you see in fixtures on the ceiling: mercury gas
is excited by an electrical charge, which in turn
excites the phosphor coating on the lamp, making
it glow. Bottom line: this process allows a compact
lamp to last for 10,000 hours, based on a three-hour
start
