OSRAM HTI 2500W/SE XS G22 - 2500W, 6000K Metal Halide Lamp for Stage Lighting

OSRAM HTI 2500W/SE XS G22 - 2500W, 6000K Metal Halide Lamp for Stage Lighting

The OSRAM HTI 2500W/SE XS with a G22 base is a short-arc discharge lamp designed for professional entertainment lighting (concerts, theater, television, and temporary architectural installations). It offers a high luminous flux of 240,000 lm , a color temperature of 6000 K , and a CRI of approximately 90 for reliable color rendering on camera and in live settings. Its XS (eXtreme Seal) technology allows for higher temperatures in the sealing area (pinch), providing robustness in demanding luminaires. It requires a sealed housing and forced cooling and must be operated with the electrical equipment specified for the luminaire (ballast/switch). The special G22 base integrates two pins and a wire to the opposite electrode, with the switch assigned to the thin pin as indicated by the manufacturer.

Product benefits

• Very high light output for high-performance projectors and moving heads in events and studios.
• Daylight color (6000 K) and CRI ≈90 for natural tones in people, clothing and scenery.
• Greater thermal robustness thanks to eXtreme Seal technology, suitable for luminaires with high thermal loads.
• Standardized geometry (G22, LCL 85 mm) that facilitates replacement in compatible equipment.

Use cases

• Live entertainment: concerts, festivals, clubs and touring shows.
• Performing arts: theatre, opera and dance, with high-powered follow spot projectors and moving heads.
• Audiovisual: TV studios, film studios and corporate events with high lighting requirements.
• Temporary architectural lighting: mappings, facades and large spaces at events.

Frequently Asked Questions

• Does it need to be installed in a closed enclosure? Yes. Due to its high luminance, UV emission, and internal pressure, it can only operate in closed enclosures with the appropriate filters.
• Does it require ventilation? Yes. Forced cooling (fan) according to the luminaire specifications.
• What do “SE” and “XS” mean? SE = Single End . XS = eXtreme Seal (greater heat resistance in the seal, up to 450 °C at the pinch).
• Is it compatible with all G22 luminaires? Only with fixtures designed for HTI 2500W/SE XS (G22 geometry and 85 mm LCL) and with the corresponding electrical equipment (ballast/ignitor). Always consult the luminaire's manual.
• Does a 600-hour lifespan mean it can't last longer? That's the nominal value under correct operating and ventilation conditions; performance may vary depending on duty cycle and maintenance.
• How is the ignition voltage applied? According to the special G22 base, the ignition voltage is applied to the thin pin ; respect the polarity indicated by the equipment manufacturer.

Installation and safety

• Use only in enclosed luminaires and with compatible electrical equipment .
• Ensure forced cooling and do not exceed the maximum temperature at the pinch.
• Avoid contact with the bulb; install with clean gloves and degrease if necessary.
• Allow the lamp to cool completely before handling it.
• Respect the connection of the special G22 base (bridged pins; opposite electrode via cable) and the ignition to the thin pin.
