Abstract
A compact electrodeless fluorescent lamp has an A-line configuration including a globular upper portion which becomes narrower toward a lower portion, terminating in a narrow end. The narrow end of the A-line envelope is connected to a base. The alternating current energy source is electrically connected through the base, via a ballast, to the excitation coil. The ballast is integral with the lamp and is contained substantially within the re-entrant cavity.
