OSRAM Baby SharXS HTI 575 W/D5/56 - Double-ended SFc11-4 metal halide lamp (5,600 K, 43,000 lm)

OSRAM Baby SharXS HTI 575 W/D5/56 - Double-ended SFc11-4 metal halide lamp (5,600 K, 43,000 lm)

The OSRAM Baby SharXS HTI 575 W/D5/56 is a twin-terminal , short-arc discharge lamp with an SFc11-4 base, optimized for moving heads and show lights (beam/spot/wash). It offers high photometric performance with a nominal luminous flux of 43,000 lm , a color temperature of 5,600 K (daylight white), and a CRI of approximately 85. Its "Baby SharXS" design standardizes the overall length to 93 mm and the pre-focus base to facilitate precise replacement and the design of compact luminaires.

It operates at 575 W with 93 V AC and 7.2 A , with 4.5/20 kVp ignition and hot-restart capability . It incorporates eXtreme Seal (XS) technology , which withstands temperatures up to 450 °C in the clamping area and requires forced cooling . The arc geometry (designation D5 ) indicates a 5.0 mm gap , with an LCL of 35 mm , a 16 mm diameter , and an approximate weight of 26 g . The rated average lifespan is 500 hours , and the operating position is Any .

Main features

• High performance : 43,000 lm, 5,600 K, CRI ~85 and efficiency ~75 lm/W thanks to the short arc.
• Compact design : Baby SharXS family with 93 mm OAL and SFc11-4 pre-focus base.
• Professional operation : hot restrike , 4.5/20 kVp ignition and forced cooling .
• Thermal robustness with XS (pinch up to 450 °C) for high-performance luminaires.
• Compatibility : Dual terminal for entertainment projectors that use SFc11-4 .

Product benefits

• Intense and defined beams due to their high luminance (≈50,000 cd/cm²) and short arc (5 mm).
• Color consistency in white daylight for mixing with LED and other discharges.
• Easy maintenance : Standardized length and base facilitate replacement and alignment.
• Reliability in continuous use thanks to arc stability and XS thermal tolerance.

Use cases

• Concerts and festivals : highly concentrated beams and far-reaching aerial effects.
• Theatre and musicals : profiles and moving heads with crisp gobos and CMY mix.
• Clubs and events : dynamic looks with a high luminous "punch".
• TV/studio and architainment : stable cool whites for camera and large spaces.

Frequently Asked Questions

• Is it dimmable with a conventional dimmer? No. HTI lamps operate with electronic discharge equipment ; do not use phase-cut dimmers.
• Can it be hot-restarted? Yes, it has hot-restrike capability (4.5/20 kVp ignition with compatible equipment).
• What is the service life? The nominal average life is 500 hours under correct ventilation and operating conditions.
• Safety requirements? Use only in enclosed housings with UV filtering; contains mercury. Always follow the luminaire manufacturer's instructions.
