OSRAM SharXS HTI 1200 W/D7/75 - Short arc metal halide lamp, double SFc10-4 (136 mm) socket for show lighting

The Osram SharXS HTI 1200 W/D7/75 is an extra-short arc (7 mm) dual- ended SFc10-4 pre-focused discharge lamp, developed for professional lighting fixtures in concert, theater, TV/studio, and architainment applications . Its SharXS design standardizes dimensions ( 136 mm overall length and 57.5 mm LCL ) for easy integration and replacement. It incorporates eXtreme Seal (XS) technology , which withstands temperatures up to 450 °C in the clamping zone and allows for hot reignition . Operating at 1200 W , ≈95 V , and 12.6 A (AC), it delivers a nominal luminous flux of 91,000 lm , a color temperature of 8800 K , and a CRI of 80 , producing a very bright, cool-toned beam for high-impact BEAM/SPOT/WASH effects. Working position: any . Requires forced cooling . Approximate weight: 33 g . For use only in enclosed luminaires with UV filtering.

Product benefits

• High efficiency and brightness with a 7mm arc for highly defined beams and high-contrast gobo projection.
• Cool and stable color (≈8800K) suitable for high impact effects and mixing with LEDs.
• Standardized dimensions within the SharXS family simplify maintenance and replacements.
• Thermal reliability thanks to eXtreme Seal (XS) , ideal for compact and demanding luminaires.
• Hot restart reduces downtime on tour or at fixed installations.

Use cases

• 1200W moving heads (BEAM/SPOT/WASH) that specify 136mm SFc10-4 lamps.
• Theatre and events with high illuminance and sharp projection requirements.
• TV/studio and architainment with cool looks and long-distance punch.

Frequently Asked Questions

• Is it compatible with any 1200W light fixture? Please check your equipment's SFc10-4 base , LCL 57.5 mm , voltage/current, and switching requirements.
• Can it be hot-swappable? Yes, with a compatible igniter/ECG (up to ~35 kVp hot-swappable according to the datasheet).
• Why do some datasheets mention 110,000 lm and 7,500 K? These are older versions/sheets of the same model; current Osram documentation specifies 91,000 lm and 8,800 K.
• Safety recommendations? Operate only in enclosed luminaires with UV filtering; contains mercury; follow the manufacturer's manual.

Technical note

The SharXS family maintains common bases and lengths (136 mm in this series), facilitating compatibility between luminaires. XS technology raises the permissible clamp temperature to 450 °C . Forced cooling is required. Typical switching current: 5/35 kVp (cooling/heating).
