OSRAM Lok-it! HTI 700 W/75/P50 - Quick-change P50 base discharge lamp (50,000 lm, 7250 K, 750 h)

OSRAM Lok-it! HTI 700 W/75/P50 - Quick-change P50 base discharge lamp (50,000 lm, 7250 K, 750 h)

The Osram Lok-it! HTI 700 W/75/P50 is a professional entertainment metal halide lamp with a bayonet-lock P50 (Lok-it!) base for ultra-fast replacement . Its short-arc architecture delivers 50,000 lm at 7,250 K (CRI > 75), maintaining consistent lumen output throughout its lifespan. It features eXtreme Seal (XS) , which withstands temperatures up to 450 °C in the clamping zone, and an improved ceramic base suitable for ignition voltages up to 35 kV . With a power rating of 700 W , 100 V , and 10.3 A , its compact design (Ø 25.0 mm , length 125.0 mm , LCL 65.0 mm ) and 4.0 mm cold electrode spacing enable highly focused beams in small-format BEAM/SPOT/WASH fixtures. Reference nominal life: 750 h . For exclusive use in enclosed luminaires with UV protection.

Product benefits

• Greater luminous efficacy compared to conventional HIDs ⇒ more efficient luminaires.
• Quick lamp change thanks to the Lok-it! system (turn and lock), minimizing downtime on tour or rental.
• Highly concentrated beam due to the short arc (4.0 mm between electrodes) and compact dimensions.
• Thermal resistance and reliability in high-load appliances thanks to XS (eXtreme Seal).
• Reliable start-up with equipment requiring up to 35 kV of starting voltage.

Use cases

• High-performance BEAM/SPOT/WASH moving heads with P50 base.
• Theatre, television and film for intense effects and high contrast gobo projection.
• Events and “architainment” that demand extreme brilliance and quick replacements.

Frequently Asked Questions

• Is it interchangeable with any 700W lamp? No. Check P50 base , LCL 65mm and electrical requirements (100V/10.3A) of the luminaire.
• Is it hot-reignitable? Use the igniter/ECG specified for the luminaire. The base supports up to 35 kV ignition.
• What maintenance does it require? Follow the manufacturer's schedule; irradiance degrades over time. Replace approximately every 750 hours or according to sensor/hour meter readings.
• Safety recommendations? Operate only in enclosed luminaires with UV filtering; handle with gloves; manage waste due to mercury content.

Installation and safety recommendations

• Check the distance from the light center (LCL 65 mm) and the seat on the P50 base to maintain optical focus.
• Ensure adequate cooling and ventilation according to the light fixture.
• Avoid touching the bulb; clean with a lint-free cloth if necessary.
