Abstract
A method of making a compact fluorescent lamp by providing a sealed, exhausted and prefilled light emitting capsule which is mounted within a jacket formed from a glass transparent to a given range of radiation. The jacket is then exhausted, filled and sealed with the same pressure and type buffer gas as is contained in the light emitting capsule. A laser then pierces the capsule allowing communication of gases in the outer jacket with those in the light emitting capsule. This permits a much faster exhaust sequence for the light emitting portion of the lamp and outer jacket.
