OSRAM HMI DIGITAL 4000 W - 6000 K HMI Lamp with UV-Stop for Cinema, TV and Studio

OSRAM HMI DIGITAL 4000 W - 6000 K HMI Lamp with UV-Stop for Cinema, TV and Studio

The Osram HMI DIGITAL 4000 W is a high-performance HMI discharge lamp designed for professional film, television, and studio productions. It offers a color temperature of 6000 K (daylight) with a CRI > 90 for accurate color rendering and a nominal luminous flux of 387,000 lm , resulting in very high illuminance levels for outdoor or large sets. Its UV-Stop (UVS) quartz construction reduces ultraviolet emission, making it suitable for use in professional-grade enclosed fixtures. The lamp supports hot-restart and, when combined with high-frequency electronic ballasts, minimizes flicker at high speeds (≈1000 Hz or higher) . With a G38 base , 200 V , and 24 A , it is a robust and efficient lighting solution for 4 kW lighting systems requiring stable, constant daylight output.

Product benefits

• Realistic in-camera color: CRI > 90 and 6,000 K to match with daylight or blend with other daylight sources without unwanted color casts.
• Very high output: 387,000 lm to cover large areas, outdoors or long distance shots with modifiers.
• High-speed filming without artifacts: flicker reduction when used with high-frequency electronic ballasts.
• Professional operation: supports hot restart, optimizing changes and resets during the day.
• Enhanced safety: UV-Stop quartz that limits UV emission and robust construction for transport.

Use cases

• Key light daylight in exteriors or interiors with a window, maintaining chromatic consistency.
• Backlight / Powerful rim for separating subjects in large sets.
• Slow motion (high speed) lighting with electronic ballasts of ≈1000 Hz or higher.
• Theatre and studio : wash or long-distance projection with compatible Fresnel/Par lenses.

Frequently Asked Questions

Does it need a ballast? Yes. It requires a 4 kW / 200 V electronic ballast compatible with HMI lamps and G38 sockets.

Is it suitable for slow motion? Yes, when combined with high-frequency electronic ballasts (≈1000 Hz or higher) it reduces visible flicker in high-speed shooting.

Can I use it in any orientation? Yes, any working position is supported.

What safety precautions should I take? Operate only in enclosed HMI lamp fixtures . Do not touch the quartz bulb, wear gloves and safety glasses, and follow the manufacturer's instructions.

Usage and safety recommendations

• Install and switch on only with equipment certified for 4 kW HMI and G38 socket.
• Allow adequate ventilation of the light fixture and respect cooling times before handling.
• Avoid contaminating the quartz: do not touch the bulb with your hands; if this happens, clean with isopropyl alcohol.
• Manage the end-of-life of discharge lamps as waste in accordance with local regulations.
