ABSTRACT:
An improved method and apparatus for use in photometric testing of high intensity discharge lamps and luminaires is disclosed. The improved apparatus includes the creation of a mock high intensity discharge lamp having an incandescent emitting element replacing the arc plasma of the subject high intensity discharge lamp while carefully duplicating all other structural and electrical details of the lamp. The improved method incorporates the use of the mock high intensity discharge lamp to obtain accurate testing of the photometric qualities of the regular high intensity discharge lamp.
