Use of Single-Ended Discharge Lamps in Modified Tungsten Halogen Luminaires
Recent developments in single-ended discharge lamps have resulted in designs which exhibit improved stability and color uniformity, thus matching the convenience of tungsten halogen lamps. With rising energy costs, the film and television industry has shown an increased interest in the use of such metal-halide lamps because of their high luminous efficacy and resulting lower running costs than tungsten lighting. However, one of the major factors limiting the widespread usage of discharge lamps is the capital expenditure to cover the need for ancillary gear and custom-designed luminaires. To minimize these costs there has been a growing interest in converting existing studio halogen luminaires so that they can house these single-ended discharge lamps. A critical assessment is made of the possibilities and limitations of such conversions for lamps with ratings from 200 W to 2 ½ kW.
