How does Pulse Start Metal Halide technology operate?
Lamp manufacturers sought to improve standard probe start metal halide lighting (175 to 1000W). They did so by changing the chemistry and fill pressure in the lamp arc tube to increase lumen efficacy (lumens per watt). These lamp improvements required
introduction of an ignitor which typically range from 50-400 Watt Metal Halide Ignitor to 1000 Watt High Pressure Sodium or Metal Halide Ignitor or starter to provide a high voltage starting pulse, eliminating the internal starting probe and its bi-metallic switch. Removal of the starting probe and switch from the arc tube construction allowed an optimized arc tube design and
manufacturing process. This technology improved the overall performance of metal halide systems. Lumen output per watt consumed can increase by 25%. Lumen maintenance is improved as much as 15%, lamp life is extended, warm-up time (The time it takes for a lamp to produce 90% of its initial light output when it is started) is reduced to two minutes, and there is some improvement in color rendition.
Adding an Ignitor reduced re-strike time to 4 to 5 minutes from the standard metal halide lamp time of 10 to 20 minutes.
