Excellent work as usual Andrew.
Anything on this site work for you?

Thanks for the comments and link Lee. It seems that their brightest is 220 lumens which is about the same as the existing incandescent bulb.

Would a halogen bulb be too hot, Andrew? They come in a variety of shapes and sizes, with and without reflectors. They feed pretty easily from any 12V power supply, including batts. You probably can still get a 9 cell Nimh pack from hobbyists sites (or probably you already have a batt supplier you like).

I think as well as the heat Steve, the issue would be getting the filament where the current one sits, which is really very close to the glass at the top where the 'pip' is on halogens :(
I'm persuing the possibility of putting a ring of bright LEDs around the objective lens, thus eliminating losses through the prism - this was suggested on the UK-d-i-y newsgroup

Andrew - could you maybe vector the light through a bundle of cheap plastic optical fibre? you could then have as physically-large a lamp as you wanted? also keeps the heat away from 'the sharp end' ?
