مصباح بروجيكتور Lamps A1/220 (BRL) 12V/50W

The 2-pin fit was exactly 6.35mm as listed, so it slid right into my projector with zero fuss. Light output is bright and even, and for a 50-watt capsule with a 50-hour rating, it's doing exactly what it should. Can't ask for more from a lamp like this.

My old bulb died mid-film and this one dropped in without any fiddling. The 12V/50W output is just right for my projector and the 50-hour rating gives me peace of mind.

The 2-pin base at 6.35mm snapped right into my old slide projector without any fiddling—perfect fit. Brightness is solid for a 50W capsule and it's been running hot for about four hours now with no flicker. Just wish the rated life were longer than 50 hours, but that's the spec I signed up for.
