Philips MSR 575 HR - G22 Metal Halide Lamp (575 W, 6000 K, Hot Restrike)
The Philips MSR 575 HR is a G22 metal halide discharge lamp designed for professional entertainment, theater, and television lighting fixtures. It belongs to the MSR Hot Restrike family, enabling hot restrike and a warm-up time of approximately 2 minutes . It offers a color temperature of 6,000 K , a CRI of 90 , and a nominal luminous flux of 48,000 lm (min. 43,200 lm), with a universal operating position and dimming capability . Its short 7 mm arc focuses the light for efficient collection and a sharp beam, ideal for moving heads, profile lights, and follow spots . It incorporates Philips P3 technology to operate at higher temperatures while maintaining beam quality. Average lifespan: 1,000 hours .
