Philips MSR 1200 - G22 Metal Halide Lamp (5,900 K, 1,200 W, 800 h)
The Philips MSR 1200 is a single-cap G22 metal halide discharge lamp for professional use in lighting fixtures and follow spots. It offers 5900 K daylight with a CRI of 80 and a nominal luminous flux of 103,000 lm , providing a powerful beam and consistent colors for stages, theaters, studios, and events. Its short 10 mm arc optimizes light gathering, while the universal operating position simplifies integration into numerous G22-based fixtures. The MSR 1200 is non-dimmable and does not support hot-strike ( cold strike system); it requires appropriate auxiliary equipment (ballast/ignition). Average life: 800 hours . Typical dimensions: Ø 40 mm , LCL 85 mm , and overall length 175 mm ; current 13.8 A and efficacy 88 lm/W .
