OSRAM HTI 150 W — GY9.5 “daylight” metal halide entertainment lamp (beam/scan/spot)

OSRAM HTI 150 W — GY9.5 “daylight” metal halide entertainment lamp (beam/scan/spot)

The OSRAM HTI 150 W is a short- arc metal halide lamp designed for entertainment lighting fixtures— scanners, moving heads, and compact projectors —that require very high luminance , a sharp beam, and a cool, daylight-like color temperature . With 150 W and a nominal voltage of 95 V , it delivers 9,500 lm with an efficacy of 67 lm/W , a CCT of 6,500 K , and a CRI of 70 , maintaining stable output throughout its nominal life of 750 hours . Its GY9.5 base , 30 mm LCL , and ultra-compact body ( Ø 20 mm , length 46 mm , 9.3 g ) facilitate integration into small form factor fixtures.

The eXtreme Seal (XS) construction withstands temperatures up to 450°C when clamped and requires forced cooling (fan) for optimal performance and lifespan. It features an operating position of any orientation and a cold start voltage of 4.5 kVp . Its rich line spectrum and stable color make it a proven choice for mid-air effects, high-contrast gobos, and projection in clubs, theaters, and events.

Main features

• Extremely high luminance per short arc (5 mm electrode gap) for defined beams and great "punch".
• Daylight : 6,500 K (typical, some commercial listings cite ≈6,900 K due to tolerances).
• Ultra-compact GY9.5 format : Ø 20 mm, length 46 mm, LCL 30 mm , weight 9.3 g.
• Nominal life 750 h with uniform output during the usage cycle.
• XS 450 °C and forced cooling for maximum reliability in touring rigs.

Product benefits

• High efficiency compared to incandescent bulbs, reducing consumption and heat per lumen emitted.
• Cool and bright color that enhances gobos and "mid-air" effects on stage and in clubs.
• Easy integration into compact luminaires thanks to the standard GY9.5 socket.
• Consistency of color and flow throughout the life of the lamp.

Use cases

• Entertainment : compact moving heads, scanners and 150W effects projectors.
• Theatre and events : texture effects, cutouts and cool accent lighting.
• Club & disco : aerial beams with long range and high contrast.

Common compatibilities (examples, always check your device's documentation)

• Martin : RoboScan 812, RoboColor III, MiniMAC (Wash/Spot) and derivatives.
• American DJ (ADJ) : Auto Spot 150 (HTI150 lamp).
• Chauvet : Legend 150R and equivalent HTI150 equipment.

Frequently Asked Questions

Can I dim it with a conventional dimmer? No. As a discharge lamp, it is not in-line dimmable ; it must be operated with a suitable ballast/ECG and ignitor from the luminaire manufacturer.

6,500 K or 6,900 K? The official data sheet indicates 6,500 K. Some distributors list approximately 6,900 K ; these are catalog variations and tolerances. The visual difference is small.

Hot restrike? Not specified for this model; after a shutdown, allow to cool according to the equipment's recommendations.

Safety and handling

• Exclusive use in closed housings due to its high luminance, UV and high internal hot pressure.
• Contains mercury : follow local regulations for handling and recycling.
• Install with forced ventilation , respect polarity/connections and avoid touching the quartz with your hands.
