OSRAM 8022 - BA20d 50W 12V Halogen-Free Incandescent Lamp for Projection and Optical Equipment
The OSRAM 8022 is a low-voltage, halogen-free incandescent lamp designed to provide focused and stable illumination in film projectors and optical and scientific equipment (microscopy, laboratory and analysis, fiber optic illumination, and medical applications). With a BA20d base and compact dimensions ( 35 mm diameter , 69 mm length ), it features a 39.5 mm LCL (Lower Closed Lens) for precise focusing in reflector systems. Rated at 50 W at 12 V , it has a typical lifespan of 50 hours and a maximum clamping temperature of 350 °C, requiring careful handling of the lampholder. Instant-on and dimmable with appropriate equipment, it is manufactured to OSRAM quality standards for reliable performance in professional use.

Frequently Asked Questions
-
Is it halogen? No. It's a low-voltage , halogen-free incandescent lamp .
-
Is it adjustable? Yes, the technical specifications indicate it is adjustable ; use compatible power supply/driver to avoid overload or flickering.
-
Is it suitable for any orientation? The working position is specific (Other / h105) . Check your luminaire/projector manual to confirm the permitted orientation.
-
Useful life? Approximately 50 hours under nominal conditions.
-
What should I keep in mind when installing it? Respect the maximum clamping temperature (350 °C) and avoid mechanical stress on the BA20d lamp holder.
Usage and safety recommendations
- Check the compatibility of the equipment (voltage 12 V, BA20d socket, burning position supported by the luminaire).
- Avoid touching the bulb with your fingers and ensure adequate ventilation in the accommodation.
- Do not exceed the clamping temperature of 350°C ; use lamp holders and cables of the appropriate thermal category.
- For dimming, use quality power supplies/regulators and verify that the equipment allows dimming with 12V incandescent lamps.
