OSRAM SharXS HTI 700 W/D4/75 - 700 W Short Arc Discharge Lamp, SFc10-4 Base, 7500 K and 59,000 lm

OSRAM SharXS HTI 700 W/D4/75 - 700 W Short Arc Discharge Lamp, SFc10-4 Base, 7500 K and 59,000 lm

The Osram SharXS HTI 700 W/D4/75 is a short-arc , double-ended metal halide lamp designed for professional lighting in entertainment and performance . It belongs to the SharXS family, characterized by standardized dimensions that facilitate replacement in compatible fixtures. With 700 W of power, a nominal voltage of 70 V , and hot restrike capability , it offers a luminous flux of 59,000 lm , a color temperature of 7,500 K , and a CRI ≥ 80 , providing a very bright, cool-to-neutral beam for concerts, theater, TV/studio, and temporary architectural installations. Its pre-focused SFc10-4 base ensures precise installation; the 57.5 mm LCL and overall length of 136 mm maintain mechanical compatibility with luminaires using this family. XS (eXtreme Seal) technology allows it to withstand up to 450°C in the clamping area , improving thermal resistance. Rated life: 750 hours . For exclusive use in enclosed luminaires with UV filters .

Main features

Product benefits

• High light output (59,000 lm) with a 7,500 K color temperature for sharp cuts and high visual impact in projection and moving heads.
• Color stability with CRI ≥ 80 that helps maintain naturalness on skin and sets under cameras and at a distance.
• Mechanical compatibility thanks to the standardized dimensions of the SharXS family (LCL 57.5 mm and length 136 mm).
• Reduced downtime due to its hot restart capability in luminaires with compatible ballast/ignition.
• Thermal reliability through eXtreme Seal (XS) , useful in compact devices with high internal temperatures.

Use cases

• Moving heads and follow spots that specify 136mm SFc10-4 lamps in live environments.
• Theatre and opera: cold key lighting and sharp cutouts on demanding stages.
• Television/studio: high brightness effects and projections with good color reproduction.
• Corporate events and “architainment”: long-distance gobo and beam projections.

Frequently Asked Questions

• Is it suitable for home lighting? No. It is a professional entertainment lamp; it must be used in enclosed fixtures with UV filtering.
• Does it require a specific ballast/igniter? Yes. It requires 700 W/70 V equipment compatible with ignition voltages of 3/25 kVp.
• Does it support hot re-ignition? Yes, provided the light fixture/lighter supports it.
• In what position can you work? In any position.
• How to handle it safely? Always wear clean gloves; avoid touching the bulb; wear safety glasses when installing; dispose of according to regulations due to mercury content.

Usage and maintenance recommendations

• Check that the SFc10-4 base and the 57.5 mm LCL match the luminaire to maintain optical focus.
• Avoid rapid on/off cycles; respect the luminaire manufacturer's timings to maximize lifespan.
• Replace when you notice loss of flow , abnormal coloring , or difficulty igniting .
