OSRAM HTI 250 W/32 C – Short arc lamp with cold light reflector for injection into light guides (5,600 K)

OSRAM HTI 250 W/32 C – Short arc lamp with cold light reflector for injection into light guides (5,600 K)

The OSRAM HTI 250 W/32 C is a short-arc metal halide (HID) lamp with a cold-focus reflector , designed for efficient fiber optic light injection . Its precise reflector alignment concentrates the luminance into a very small spot, ideal for medical endoscopy , industrial boroscopy , and light-guiding systems in entertainment. Operating at 45 V and 6 A ( 250 W AC ), it offers a color temperature of 5600 K with a CRI of 70 and a rated lifespan of 250 hours . Its optimized optics feature a 32 mm working/focal distance , a 67 mm diameter , and a 73 mm overall length . The FaXP2.5-2×65 base (special plug-in) facilitates easy mounting on fiber optic light sources. It is a compact and robust solution with stable light output throughout its lifespan.

Main features

• Short arc with cold light reflector for efficient coupling to light guides and collectors.
• 250 W · 45 V · 6 A (AC) ; 5,600K , CRI 70 .
• Working/focal distance 32 mm for maximum transfer to fibers (>1 mm).
• Compact format : Ø 67 mm · length 73 mm ; weight 115 g .
• FaXP2.5-2×65 base (special plug-in connector) for quick and secure integration.
• Uniform light output and low flux depreciation over lifetime.
• Hot start with suitable equipment and burn position P20 (horizontal ±20°).

Product benefits

• Outstanding efficiency in injecting light into fibers thanks to the precise focusing of the reflector.
• Daylight color 5,600 K for faithful reproduction in cameras and vision systems.
• Stable operation (lumen maintenance) that reduces recalibrations in optical equipment.
• Robust design for intensive cycles in laboratory, operating room or industrial testing.

Use cases

• Medical endoscopy and fiber optic illumination in hospital light sources.
• Industrial boroscopy and non-destructive inspection .
• Entertainment : injection of light guides and specialized lighting effects.
• Studio/TV and photography when a high luminance light point is required.

Frequently Asked Questions

• What does “/32 C” mean? It identifies the 32mm working/focal distance of the cold-light reflector assembly, optimized for attaching to light guides.
• Does it require a specific ballast/ignition? Yes. It requires HID lamp equipment with hot reignition capability and high ignition voltage.
• What is the working position? P20 (horizontal ±20°) according to product specifications.
• Is it safe to look at? No. It should only be used in enclosed housings with suitable filters due to its high luminance, UV radiation , and high internal pressure .

Usage and safety recommendations

• Always operate in closed housings and with UV filters according to the manufacturer's instructions.
• Install with the approved auxiliary equipment for 250 W/45 V and hot restart.
• Avoid touching the reflector/window; clean with a lint-free cloth if necessary.
• Manage end of life in accordance with regulations (contains mercury).
