OSRAM HMI DIGITAL 400 W/SE GZZ9.5 - Daylight HMI Lamp for Cinema, TV and Photography

OSRAM HMI DIGITAL 400 W/SE GZZ9.5 - Daylight HMI Lamp for Cinema, TV and Photography

The OSRAM HMI DIGITAL 400 W/SE is a metal halide ( HMI ) discharge lamp specifically designed for professional audiovisual production in studios and outdoors. It offers stable daylight with a nominal color temperature of 6,700 K (simulating natural light inside the fixture), a high color rendering index (CRI > 90) , and a luminous flux of 32,500 lm for intense and homogeneous illumination. Its single-ended design with a GZZ9.5 socket , 60 mm LCL , and compact body ( Ø 23 mm, length 110 mm ) makes it compatible with numerous PAR, Fresnel, and HMI heads.

The HMI DIGITAL family incorporates UV-Stop (UVS) , hot-swappable power-up , and a design optimized for use with high-frequency electronic ballasts , reducing flicker in high-speed cameras. Furthermore, its eXtreme Seal (XS) technology and robust materials ensure durability on tours and film sets. With a nominal power of 400 W , 75 V , and 5.3 A , it offers an average lifespan of 650 hours in universal operating mode.

• Technical applications : solar simulation and tests requiring a daylight spectrum.

Frequently Asked Questions

Do I need a ballast? Yes. HMI lamps require a ballast (preferably a high-frequency electronic ballast to reduce flicker ).

Can it be dimmed? With many electronic ballasts it is possible to dim up to approximately 40% while maintaining good color stability.

Can it be hot-restired? Yes, the DIGITAL series supports hot restrike with the appropriate ballast.

Is it suitable for domestic use? No. It is a special-purpose device and must be operated in enclosed fixtures designed for HMIs.

Safety and handling

• Use only in enclosed housings specifically designed for HMIs. The lamp operates at high internal pressure and emits UV radiation.
• Quartz with UV-Stop reduces UV radiation, but the luminaire manufacturer's screens and filters must be respected.
• Contains mercury : follow local regulations in case of breakage and for recycling.
• Do not touch the bulb with your hands: handle with clean gloves.

Compatibility and installation

• Check that the luminaire supports GZZ9.5 , LCL 60 mm and a power of 400 W.
• For high-speed cameras, use high-frequency electronic ballasts to minimize flicker.
• Respect ventilation and thermal limits of the light manufacturer (base up to 350 °C).
