It is not widely known
that a new type of
lamp was introduced
in the 1980s: the
induction lamp. The
design of this lamp,
which has no electrodes,
ensures that
its useful life is not
less than 6000–60000
hours. This means
that the lamp, assuming
it is on for six
hours a day, will last
for 3–25 years. This
article gives a brief
description of the
design.
