OSRAM HTI 1500/60/P50 (Lok-it!) - 1500W, 6000K Metal Halide Lamp, PGJX50 Base for Moving Heads and Stages

OSRAM HTI 1500/60/P50 (Lok-it!) - 1500W, 6000K Metal Halide Lamp, PGJX50 Base for Moving Heads and Stages

The OSRAM HTI 1500/60/P50 Lok-it! is a short-arc discharge lamp designed for professional entertainment equipment (moving heads, theater, TV, and events). Its twist-and-lock Lok-it! base makes bulb replacement quick and easy, while eXtreme Seal (XS) technology allows pinch temperatures up to 450°C . It delivers a nominal luminous flux of 130,000 lm with a color temperature of 6,000 K and a CRI ≥85 (typically close to 90), maintaining stable output throughout its lifespan. It requires an electronic ballast and operation in a closed luminaire with UV filtering.

Main features

• Power / voltage / current: 1,500 W · 100 V · 15 A.
• High performance light: 130,000 lm · 6,000 K · CRI ≥85.
• Base and mounting system: PGJX50 with Lok-it! (one-touch twist and lock) for quick replacements.
• Optics and geometry: LCL 65 mm · diameter 29 mm · length 128 mm (compact format for bright projectors).
• Thermal and electrical robustness: XS sealing up to 450 °C and ceramic base prepared for ignition voltages up to 35 kV .
• Nominal service life: 750 h (reference conditions).
• Working position: wide range of capabilities (refer to equipment specification).
• Safety: Mandatory use in enclosed areas with UV filters; high luminance lamp and internal pressure.

Product benefits

• Very high luminance from a point source for defined beams and high-impact effects.
• Consistent daylight color (6,000 K) and reliable color reproduction in cameras and by eye.
• Quick and easy replacement thanks to the Lok-it! system (turn and lock).
• Stable output throughout the service life, reducing variations between replacements.

Use cases

• 1.5 kW moving heads for concerts, festivals and touring .
• Theatre, TV and film , where intense light and neutral color are required.
• Corporate events and large venues that demand concentrated beams and high punch .

Typical compatibility (examples)

Used in numerous 1500W moving head fixtures. Documented examples include Martin MAC III systems (internal lamp references) and cross-equivalents to Philips MSR Gold 1500 FastFit fixtures from brands such as Robe, Claypaky, and Coemar. Always verify the exact reference required by your fixture before purchasing.

Frequently Asked Questions

• Is it adjustable and does it support hot re-strike? Yes; adjustment and hot re-strike depend on the projector's electronic ballast.
• Does it generate ozone? Standard HTI models; always follow the manufacturer's safety instructions and use in a closed luminaire with UV filtering.
• What maintenance is required? Keep the seats clean, check ventilation/airflow, and respect cooling times according to the equipment.

Installation and safety

• Operate only with compatible electronic ballast , respecting polarity and electrical parameters of the manufacturer.
• Install in a closed housing with UV filters and mechanical protections; avoid direct exposure due to its high luminance and pressure.
• Handle with PPE and protective cover; do not touch the quartz.
