OSRAM HSD 150/70 G12 - 150W, 7000K Metal Halide Lamp for Stages and Theatres
The OSRAM HSD 150/70 is a 150W metal halide discharge (HID) lamp with a G12 base, specifically designed for entertainment and architectural lighting (stages, theaters, concerts, clubs, and "architainment" spaces). It offers a color temperature of 7000K (cool daylight), a nominal luminous flux of 12,000 lm , and a CRI of 85 , providing a sharp, high-intensity beam ideal for projectors and special effects luminaires. Its quartz outer casing and eXtreme Seal allow it to withstand temperatures up to 450°C in the clamping area, ensuring robustness and stability. With a nominal lifespan of up to 3000 hours (when operating with electronic equipment), it reduces maintenance time compared to shorter-life alternatives.
Operating at 97 V and 1.6 A AC , it requires compatible control/switching equipment (ECG/ballast) . Its single-ended design with a T6 bulb and compact dimensions ( Ø 20 mm , length 105 mm ) facilitates integration into moving heads, profile lights, Fresnel lights, and projection fixtures with a G12 base. The resulting luminous efficacy is approximately 80 lm/W (12,000 lm at 150 W), with maximum values up to 90 lm/W according to the manufacturer's datasheet.
Usage note: This lamp is designed for stages and theaters and is not suitable for residential lighting due to its high luminance, UV emission and specific safety requirements.

Frequently Asked Questions
-
Does it need a ballast/igniter? Yes. It requires electronic control equipment (ECG) and ignition suitable for 150W/97V HSD lamps.
-
Can it be hot-restarted? As an HID lamp, immediate hot-restarting may be limited by the equipment; follow the luminaire manufacturer's instructions.
-
Does it emit UV? Yes. It must be used in enclosed housings with filters that reduce UV radiation to safe levels.
-
Is it suitable for home use? No. It is a professional product for entertainment and architectural use .
Installation and safety recommendations
- Always operate in enclosed luminaires designed for high-pressure lamps; avoid direct UV exposure.
- Do not touch the quartz with your hands; handle with clean gloves to avoid contamination of the bulb.
- Allow to cool before handling; the lamp operates at high pressure and temperature.
- Manage waste in accordance with current regulations; may contain mercury.
