OSRAM EMH 575W/DE/60 (SFc10-4) – Double-ended metal halide lamp, 6,000 K (alternative to HMI 575W/DE/60)

OSRAM EMH 575W/DE/60 (SFc10-4) – Double-ended metal halide lamp, 6,000 K (alternative to HMI 575W/DE/60)

The OSRAM EMH 575W/DE/60 is a double-ended metal halide lamp with an SFc10-4 base at both ends, designed to offer high luminance and excellent efficiency in entertainment , projection , and display/optical lighting applications . With a wattage of 575 W , 95 V , and 7 A , it provides a luminous flux of 42,000 lm at 6,000 K ( daylight ) and achieves approximately 85 lm/W . It is hot-restart ready and can operate with both standard ballasts and electronic ballast generators (ECGs) . In terms of geometry and performance, it is similar to the HMI 575W/DE/60 , maintaining dimensional compatibility (maximum length 135 mm , diameter 24 mm ) and universal burn-in position .

Main features

• Power and performance : 575 W · 95 V · 7 A · ~ 85 lm/W efficiency.
• Daylight : 6,000 K with 42,000 lm for bright and clear beams.
