Abstract
A high intensity discharge lamp (e.g., a metal halide) containing an arc tube having first and second electrodes respectively sealed at opposite ends thereof. An outer envelope surrounds the arc tube and has a lamp base disposed at one end thereof. The lamp base has first and second terminals for electrical connection to the arc tube. The lamp further includes means for electrically coupling each of the base terminals to a respective electrode of the arc tube. A starting circuit is disposed within the lamp electrically connected in parallel with the arc tube. The starting circuit comprises a non-linear dielectric element (e.g., a non-linear capacitor) and a glow capsule. The glow capsule is located within the outer envelope proximate the arc tube and adapted to produce ultraviolet radiation.
