OSRAM HTI 1200 W/SE XS - Short arc discharge lamp for stage lighting, GY22, 5400 K

OSRAM HTI 1200 W/SE XS - Short arc discharge lamp for stage lighting, GY22, 5400 K

The OSRAM HTI 1200 W/SE XS is a short-arc metal halide lamp designed for professional stage and entertainment lighting applications (concerts, theater, television/studio, and events). Its combination of high luminance and high luminous flux (105,000 lm) provides intense, long-range beams with excellent color rendering (CRI > 90) . With a power rating of 1200 W , a nominal voltage of 95 V , and a nominal current of 13.8 A , this SE (Single End) version with a GY22 base incorporates XS (eXtreme Seal) technology, certified to withstand up to 450 °C in the clamping zone, thus improving thermal resistance in high-performance luminaires with forced cooling.

Its color temperature of 5,400 K and luminous efficacy of 85 lm/W provide a neutral, daylight-like white light that maintains color vibrancy on stage and on camera. With a nominal lifespan of 750 hours , a total length of 135 mm , a diameter of 29 mm , and an LCL of 59 mm , it fits GY22-based compatible moving heads and projectors that require fan cooling and enclosed housings.

Main features

• Type: Metal halide HID discharge lamp, short arc, single end .
• Base: GY22 (apply power-on voltage to the thin pin).
• XS Technology (eXtreme Seal): up to 450 °C in the clamping zone for greater thermal robustness.
• Power / voltage / current: 1,200 W / 95 V / 13.8 A.
• Luminous flux: 105,000 lm; efficacy: 85 lm/W.
• Luminance: 26,000 cd/cm² for highly concentrated beams.
• Color / CRI: 5,400 K (neutral white) / Ra > 90 .
• Nominal lifespan: 750 h (professional use, with forced cooling).
• Dimensions: length 135 mm; diameter 29 mm; LCL 59 mm ; gap between electrodes 7 mm.
• Operating conditions: “Other” working position (power cord underneath); fan cooling .
• Ignition: 4.5/25 kVp (start-up voltage).
• Areas: concerts, clubs, theater, TV/film and architainment .

Product benefits

• Powerful and defined projection thanks to its high luminance and CRI > 90, ideal for "punchy" beams and faithful colors on stage and camera.
• Stable performance in demanding luminaires thanks to XS technology and its thermal tolerance.
• Daylight white (5,400 K) that maintains the contrast and naturalness of skin and clothing.
• Extended compatibility with equipment using GY22 socket and proper ignition.

Use cases

• 1200W spot/profile moving heads with GY22 base.
• Manual follower/spot in theaters, auditoriums and event venues.
• Projectors for television, filming and studio use, when a high CRI is required.
• Temporary architectural lighting ( architainment ) in shows.

Frequently Asked Questions

• Can I use it in open light fixtures? No. It must operate exclusively in enclosed housings designed for this purpose and with suitable UV filters .
• Does it require ventilation? Yes, forced fan cooling to ensure stability and lifespan.
• What does XS mean? eXtreme Seal : greater heat resistance in the clamping zone (up to 450 °C).
• Is it suitable for generic 1200W ballasts? It must be used with ignition/starting equipment and ballast compatible with 95V, 13.8A and 4.5/25 kVp priming.

Safety and professional use notes

Due to its high luminance, UV radiation, and high internal pressure during operation, this lamp can only be used in specifically designed , enclosed luminaires . Effective UV filters must be incorporated. In case of breakage, mercury may be released; follow the handling, personal protective equipment, and hazardous waste disposal protocols indicated by the manufacturer and applicable regulations.
