OSRAM EMH 575 W/DE/75 – Double-ended SFc10-4 metal halide lamp for show (6000 K, 42,000 lm)

OSRAM EMH 575 W/DE/75 – Double-ended SFc10-4 metal halide lamp for show (6000 K, 42,000 lm)

The OSRAM EMH 575 W/DE/75 belongs to the Classic EMH line, OSRAM's economical alternative to the popular 575 W HMI lamps. It is a short-arc , double-ended lamp with an SFc10-4 base, designed for moving heads , stage projectors , and studio/TV lighting . Its very short arc provides high luminance and a high useful flux , with a color temperature of 6000 K (daylight) and a CRI > 60. The average rated life is 750 hours , and the operating position is universal , facilitating its integration into numerous SFc10-4 compatible devices.

It operates at 575 W with 95 V and 7 A ; it supports hot start with a 4.5 kV (kHz) or 7/20 kV (MHz, cold/hot; max. 25 kV) ignition. It delivers an approximate luminous flux of 42,000 lm and maintains stable light output throughout its lifespan when operated with the appropriate control equipment. Due to its high luminance , UV radiation , and high internal pressure , it must always be used in enclosed luminaires with UV filtering.

Product benefits

• High-quality, effective light with an excellent price-performance ratio (Classic EMH line).
• High luminance per short arc: powerful beams, gobos and defined effects.
• Flexible installation : SFc10-4 base and Universal position for multiple luminaires.
• Professional operation : hot restrictrike and ECG compatibility to minimize flicker.

Use cases

• Concerts, theater and events : 575W beam/spot/wash moving heads.
• TV and studio : balanced daytime whites and high "punch".
• Retail, clubs and small rooms : projection of effects and bright accents.

Frequently Asked Questions

• Is it "the same" as an HMI 575W/DE/75? It's similar in format and wattage ; the EMH is OSRAM's budget version with close specifications . Check the electrical/optical requirements with your luminaire manufacturer.
• Is the color temperature 6000 K or 7500 K? The latest datasheet specifies 6000 K ; older OSRAM documentation and some distributors list 7500 K for this reference “/75”. Check the color calibration required for your application.
• Can it be regulated with a phase-cut dimmer? No. Discharge lamps are operated with a ballast/ECG ; do not use mains dimmers.
• Safety requirements? Use only in enclosed housings with UV filters; contains mercury .

Installation and safety

• Check compatibility SFc10-4 , LCL 57.5 mm and length 135 mm .
• Respect the rated voltage/current and ignition voltages required by the ECG.
• Handle with gloves; avoid touching the quartz. Ensure adequate ventilation of the light fixture.
• End-of-life management according to WEEE regulations.
