Abstract
A three (3)-way lamp having a tungsten halogen-cycle inner envelope and an operating circuit for the inner envelope is disclosed. The operating circuit comprises a ballast element and two diodes lodged within the confines of the base of the lamp. The operating circuit allows the inner envelope to provide three different levels of illumination for the lamp while still maintaining the desired operation of the halogen additive within the inner envelope.
