economical lamps with a long life
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.
