OSRAM Lok-it! HTI 700 W/75/P28 - Short Arc Discharge Lamp PGJX28 for Moving Heads

The OSRAM Lok-it! HTI 700 W/75/P28 is a short-arc metal halide lamp designed for professional moving-head luminaires (spot/beam/wash) used in concerts, clubs, theater, TV, and architectural lighting. Its compact design with a PGJX28 (Lok-it!) base allows for ultra-fast changeovers via a twist-and-lock mechanism , minimizing downtime. It delivers 50,000 lm with a color temperature of approximately 6,700 K (CRI > 75) and a rated life of 750 hours , providing a very bright and stable beam throughout its operating cycle. The eXtreme Seal (XS) technology withstands temperatures up to 450 °C at the seal, and the ceramic base supports ignition voltages up to 35 kV . It requires dedicated electronic power supplies for HID lamps and forced cooling in enclosed luminaires.

Main features

• Power/voltage/current: 700 W · 68 V · 10.3 A.
• Output and color: 50,000 lm · ≈ 6,700 K · CRI > 75 .
• Short arc optics : 4 mm cold electrode gap for very high luminance.
• Compact geometry: LCL 56 mm , length 112 mm , diameter 23 mm .
• Quick assembly : Lok-it! system with PGJX28 and twist lock.
• Thermal resistance : XS technology (up to 450 °C on the seal).
• Professional operation : forced cooling , burn position: any , use in enclosed accommodations .

Product benefits

• Luminaire efficiency : greater effectiveness than conventional HIDs, with an intense and well-defined beam.
• Fewer stops : replacement in seconds and constant light output throughout the lifespan.
• Touring reliability : ceramic base and XS sealing to withstand high temperatures.
• Versatile integration : standard dimensions and universal burn position for multiple devices.

Use cases

• Lighting for shows : concerts, festivals and corporate events.
• Club and disco : narrow beams and high-impact effects.
• Theatre and TV : spot/beam/wash luminaires with high brightness requirements.
• Architecture and architainment : projection of long-range beams and textures.

Common compatibilities and equivalencies (examples)

Luminaire models that use Lok-it! 700 W/75/P28 lamps (always check your equipment's data sheet): Acme XP-700 SZ / XP-700A Beam, Chauvet Legend 700, Clay Paky Alpha Beam/Profile/Wash 700, among others.
Widely used alternative: Philips MSR Gold 700/2 MiniFastFit (common industry equivalent; always confirm in your luminaire manual).

Frequently Asked Questions

• Can it be installed in any orientation? Yes, burning position: any (universal), always with adequate cooling.
• Is it dimmable? Dimming depends on the electronic ballast of the luminaire; in practice, level control is usually achieved with a mechanical shutter.
• Does it require special safety measures? Yes. Due to its high luminance, UV radiation, and internal pressure , it must only be operated in enclosed housings with UV filters and forced ventilation.

Usage and safety recommendations

• Use only with ECG/ignitor approved by the luminaire manufacturer.
• Ensure airflow and maintain temperatures within limits (up to 450 °C at the XS seal).
• Handle by the base (Lok-it! system); do not touch the bulb.
• Respect the manufacturer's safety instructions (UV, mercury, internal pressure).
