Safety

Use only in equipment rated for a 50W 22.8V lamp with a G6.35 base and the required protective shield or enclosure. Disconnect power and allow the equipment to cool before service. Handle the quartz with clean gloves or a lint-free cloth.

Halogen lamps operate at high temperature and pressure and emit ultraviolet radiation. Maintain the equipment's protective optics and airflow, and follow the equipment manufacturer's replacement and disposal instructions.

The nominal life is 1,000 hours in current OSRAM data; an older 1,300-hour copied claim has been removed.
