I'm a bit lost, here.
Discharge lamps are not continuous-spectrum sources, and would probably
not
work very well when projecting color images. And with mercury, you'd have
to
filter out the UV, not to mention the ozone generated by the UV.
So am I, video projectors and back projected TVs seem to manage fine.
They don't melt or burn like film does.

Teflon coated.
