"Newer" ones use a BXM lamp and "much older" ones use something else, if I remember correctly.

They don't come with a regulated supply if that's what you're asking.

It sounds like you're looking at brewing your own Jax Light.

The 'older' ones used a regular screw-base bulb that had a special smooth base (with orienting pin-hole) soldered on. I just gave away about 20 of them. I'm sure many operators got burned fingers from changing out that lamp.

The exciter supply was AC, which was a really stupid thing to supply with an otherwise good projector.

The 0080 bulb filament is heavy to help dampen the A.C. noise [Roll Eyes]
