OSRAM Lok-it! HTI 700 W/60/P50 – PGJX50 Metal Halide Lamp for Moving Heads (59 V, 49,000 lm, 5,800 K)

OSRAM Lok-it! HTI 700 W/60/P50 – PGJX50 Metal Halide Lamp for Moving Heads (59 V, 49,000 lm, 5,800 K)

The OSRAM Lok-it! HTI 700 W/60/P50 is a short-arc discharge lamp with a PGJX50 (Lok-it! / FastFit) base, designed for professional entertainment lighting fixtures: concerts, clubs, theater, television/studio, and architainment . It offers a nominal luminous flux of 49,000 lm , a color temperature of 5,800 K (daylight white), and a CRI Ra 75 , with a nominal life of 750 h . The Lok-it! design allows for quick "twist and lock" replacement , and its XS (eXtreme Seal) technology withstands up to 450 °C in the clamp area, providing robustness in high-performance luminaires. Its 65 mm LCL and compact size ( Ø 25 mm, length 125 mm ) ensure easy mechanical integration into PGJX50-compatible fixtures.

The designation “/60” identifies a color temperature of approximately 6000 K , intended for applications requiring a more neutral daylight white than the /75 version. With its PGJX50 base and photometric range, this lamp is a direct alternative to the Philips MSR Gold 700/2 FastFit model in luminaires that accept this family, such as the widely used 700 W series for rental and fixed installations. Before replacing, always confirm the luminaire and ballast/igniter specifications provided by the projector manufacturer.

Product benefits

• Stable photometric maintenance throughout its lifespan, suitable for tours and intensive operation.
• Daylight white (~6000 K) that favors mixing with LEDs and modern discharges without excessive cool dominance.
• Compact format with short arc for smaller and brighter luminaires.
• Interchangeability in luminaires with PGJX50 socket, streamlining rental logistics.
• Change in seconds thanks to the Lok-it! system, reducing downtime.

Use cases

• Concerts and festivals : 700W moving head spot and wash lights with punch and neutral color.
• Theatre and musicals : balanced chromatic mixing with CMY filters and systems.
• Television and film : consistent whites on set and in studio with high illuminance.
• Clubs and corporate events : aerial effects and high-intensity beams.
• Ephemeral architecture : architainment in temporary events and mappings with 700W projectors.

Frequently Asked Questions

• Is it compatible with 700W ROBE luminaires (ColorSpot/ColorWash/ColorBeam)? Many models in this series use 700W FastFit PGJX50 lamps (e.g., Philips MSR Gold 700 FastFit). The Lok-it! HTI 700W/60/P50 shares the same PGJX50 base and electrical range, so it is often a suitable option. Always check your luminaire's manual.
• How does it differ from the /75 version? The /75 is around 7,500 K ; the /60 is around 6,000 K. The choice depends on the desired white balance.
• Does it require an enclosed luminaire? Yes. Due to its high luminance, UV radiation, and internal pressure, it must be used in enclosed housings with suitable filters.
• Can I replace an MSR Gold 700/2 FastFit with this lamp? It's usually possible with PGJX50 compatible fixtures; always confirm with the manufacturer of the specified fixture and ballast.

Installation and safety

• Install only in enclosed luminaires designed for PGJX50 and 700W discharge lamps.
• Use ignition equipment/ballast specified by the manufacturer; the ceramic base supports up to 35 kV ignition pulse.
• Handle with goggles and gloves; avoid touching the bulb.
• Respect the manufacturer's timings and procedures for safe replacement of the light fixture ( twist & lock ).
