OSRAM POWERSTAR HQI-TS | 1000W/NDL/S | K12s Daylight Metal Halide Lamp

The Osram Powerstar HQI-TS 1000W/NDL/S is a professional-grade, short-arc metal halide lamp engineered for high-intensity floodlighting and industrial applications. Delivering a powerful 90,000 lumens with a crisp 4400K Daylight color temperature, this lamp features advanced UVS (UV Filter) technology to minimize ultraviolet emissions. Designed with a K12s double-ended base and a compact 187mm profile, it offers superior optical control and an efficacy of 90 lm/W. Its hot restrike capability and 85 CRI make it an essential solution for stadium lighting, airport apron illumination, and solar simulation where color accuracy and immediate restart are critical.

Performance and Technical Advantages

Equipped with POWERSTAR Quartz Technology, this HQI-TS lamp provides exceptional color stability throughout its 6,000-hour life. The short-arc design allows for a more compact and precise luminous center, which translates to better beam focus in floodlight reflectors. With its hot restrike capability, the lamp can be reignited immediately after a power interruption, avoiding the long cool-down periods required by standard HID lamps. This makes it ideal for professional venues where lighting reliability is non-negotiable.

• Enhanced Safety: Integrated UV filter (UVS) reduces the risk of UV degradation to fixture materials.
• High Color Fidelity: 85 CRI ensures natural color rendering for broadcasting and industrial inspection.
• Precise Positioning: Supports a ±15° burning position tolerance for versatile fixture mounting.
• Thermal Stability: Compact 36mm diameter ensures efficient heat dissipation in enclosed luminaires.

Safety and Usage Notes

• Fixture Requirement: This lamp must be operated in **enclosed luminaires only** due to high internal pressure and UV output.
• Ignition: Requires a compatible ignitor providing 4.0–36 kVp ignition voltage.
• Handling: Do not touch the quartz bulb with bare fingers; oils from the skin can cause "hot spots" and lead to early failure. Use a clean cloth or alcohol to clean if touched.
• Disposal: Contains mercury; dispose of in accordance with local environmental regulations.
