Abstract
A method of prolonging the life of thin film dichroic coated lamp components and of employing inexpensive components has been discovered. This method is the use of a hydrogen getter located in the outer jacket of the lamp, adjacent to the dichroic coating. The getter is preferably located and aligned so as to reach an optimum operating temperature.
