OSRAM HTI 250w /32 arc bulb

This OSRAM HTI 250w /32 is a short arc metal halide lamp built for stage, architectural and event lighting. It delivers high lumen output with a crisp 5600K daylight colour temperature suited to automated fixtures. Professional lighting designers and venue operators will find the balance of colour performance and output useful for entertainment rigs. It is not for buyers who need extended lamp life or lower colour rendering requirements.

Sustained output and service life

The lamp is rated for 250 hours of service life under typical operating conditions. Colour temperature remains stable in the 5600K to 7800K range during continuous use in automated fixtures. The colour rendering index holds at 70 throughout the rated period. It is not for installations that demand significantly longer replacement intervals or higher CRI values.

Interface and fixture limits

The lamp uses a compact single-ended or focusing-reflector configuration designed for specific automated fixtures. Fixtures must accommodate the 250 watt power draw and the associated thermal load. Electrical and mechanical compatibility depends on the fixture manufacturer's specifications. It is not for sockets or ballasts rated for different wattages or lamp geometries.

Questions about this item

How much heat and power does the 250 W arc draw during continuous operation?

The lamp consumes 250 watts and produces a 5600 K daylight beam; expect significant heat output that requires a ventilated fixture rated for 250 W HID lamps.

What ballast and fixture must I already own for this lamp to ignite and run?

You need a compatible 250 W HID ballast and a single-ended socket fixture designed for short-arc metal halide lamps with the correct ignition voltage.

Will this 5600 K arc match the colour of my older 7800 K stage lamps?

It renders at 5600 K with a CRI of 70, so it appears warmer than 7800 K units; mixing them will create a visible colour-temperature shift on stage.
