OSRAM HMI DIGITAL 1800 W/SE UVS - Single-cap metal halide lamp for cinema, TV and stage

The OSRAM HMI DIGITAL 1800 W/SE UVS is a high-performance professional discharge lamp designed for film, television, video, and stage productions requiring intense, stable light with accurate color rendering. Its G38 (single-ended) base and UV-Stop (UVS) technology ensure safety and durability, while its design, optimized for high-frequency electronic ballasts, minimizes flicker even during high-speed shooting . With a nominal color temperature of 6,500 K (approximately 6,000 K in daylight), a CRI Ra of 90 , and a luminous flux of 165,000 lm , it delivers a bright and consistent beam that maintains accurate color reproduction on camera.

Its electronics support hot restrike , universal burn-in position , and operation on 140V/12.9A AC , ensuring compatibility with studio and location lighting equipment. OSRAM's eXtreme Seal (XS) engineering is optimized to withstand high temperatures at the base, and the lamp achieves a rated life of 750 hours under proper operating conditions. Dimensionally compact ( Ø 40 mm , length 200 mm , LCL 107 mm ), it integrates seamlessly into compatible 1.8 kW flash heads.

Product benefits

• Natural and consistent image: daylight and CRI 90 keep skin tones and art colors true in camera.
• Slow-motion productions without surprises: less risk of flicker with high-frequency ballasts for high-speed .
• Professional operation: hot start to resume shooting without long cooling times.
• Integrated safety: UV-Stop technology that reduces harmful UV radiation on the set.
• Total versatility: universal burn position and SE G38 format compatible with numerous 1.8 kW heads.
• Cost-effectiveness on set: high flow and reference efficiency that allow working with demanding lenses and diffusers without losing exposure.

Use cases

• TV and film studio: key/fill with daylight, controlling contrast with diffusers or softboxes.
• Outdoor filming: reinforcement of natural light and powerful backlighting that "match" with the sun.
• Stagecraft and events: dramatic effects, cutouts and long-running highlights.
• High-speed photography: high frame rate shots with compatible electronic ballasts.

Frequently Asked Questions

Do I need an electronic ballast? It's recommended to reduce flicker, especially in slow motion. It also allows for hot-starting and, depending on the model, some power regulation.

Can the output be adjusted? Many electronic ballasts allow dimming with good color stability; refer to the datasheet for the specific ballast for the effective range.

Does the lamp have a built-in UV filter? Yes, the quartz with UV-Stop (UVS) technology reduces UV-B and UV-C emissions. Even so, use appropriate safety accessories and practices.

When should I replace it? In addition to the nominal end of life (750 h), early replacement improves color/output consistency in critical productions.

Are there any mounting restrictions? No, the burning position is universal. Always ensure adequate ventilation of the burner and the permissible temperature at the base.

Compatibility and best practices

• Designed for high-frequency ballasts (≈1,000 Hz or higher) for high-speed rolling.
• Always install with clean gloves and degrease the bulb if necessary to avoid hot spots.
• Maintain convection or forced ventilation according to the design of the light fixture and avoid obstructions in grilles.
