ABSTRACT:
An arc discharge lamp having the ability to be easily focused is disclosed. The lamp includes a split ball assembly mounted about one end of an arc discharge tube which can be held in place by concave portions provided in a base and a locking nut. The split ball assembly also includes a rotation limiting portion to provide the ramp with a limited degree of movement in two axes. Additionally, the split ball assembly allows the lamp to be moved in a third axis. The resulting movement of the lamp allows it to be properly focused with any reflector.
