warm-up time (before it died), a xenon lamp.


It comes on just about straight away and then takes maybe 30 seconds to
get to full power. It's hard to take photos of something that is
mirrored hence the poor quality. Internally it is basically just two
wires that touch together. The bulb is about 75mm x 55mm although I
haven't taken it out of the housing so there is some error in that
measurement. There is certainly no spherical bulge in the middle the
face is perfectly flat.



I knew I'd seen it somewhere, and here it is:
