Abstract
A lamp—suitable for use within a projector or other high-light output application—includes an ultra high pressure bulb. An extension from the bulb defines a start-up bubble. A conductor is carried by the extension of the ultra high pressure bulb, generally enclosing the start-up bubble, thereby exciting gas contained within the start-up bubble. A header defines a socket within which the extension and the conductor are carried.
