OSRAM Lok-it! 1700/PS – Plug'n'play short arc HTI lamp (PGJX28), 6,000 K, high CRI for entertainment and architecture

The OSRAM Lok-it! 1700/PS is a single-ended, short-arc metal halide (HTI) lamp designed for moving heads and high-performance luminaires in entertainment, television/film, and architectural applications . Its Lok-it! plug'n'play base (PGJX28) allows for quick and precise replacement without complex readjustments, while eXtreme Seal (XS) technology provides clamping thermal resistance up to approximately 450°C , ideal for compact and powerful optical bodies. With a power rating of 1700 W , 84.5 V , and 20 A , it delivers 135,000 lm at 6000 K with a CRI ≥92 , maintaining stable light output throughout its lifespan . It features a 60 mm LCL , a 5.2 mm electrode gap (cold start) , a 121 mm length , and a 28 mm diameter , weighing 60 g . Due to its compact design, it only fires when cold (no hot restrike ).

Known compatibility (not exhaustive)

Used by various manufacturers in 1700W luminaires, including the ROBE BMFL series (Spot, Blade, Wash, Wash XF), as well as models from PR Lighting, Fine Art, Light Sky, and others. Always check the equipment documentation for the exact Lok-it! 1700/PS part number.

Frequently Asked Questions

• Does it support hot restart? No; due to its compact design, it only powers on when cold .
• Is electronic equipment (ECG) required? Yes, it is designed to work with electronic sources from the luminaire manufacturer.
• Can it be mounted in any orientation? Yes, the burn position is “Any” .
• UV/mercury precautions? Operate only in enclosed housings with UV filtering; contains mercury (Hg).

Safety and recommendations

• Operate exclusively in enclosed luminaires designed for high luminance and internal pressure lamps.
• Use appropriate filters and shielding to reduce UV radiation to acceptable levels.
• Maintain ventilation/cooling according to the bulb manufacturer's specifications.
• Manage end-of-life in accordance with regulations: the lamp contains Hg .
