Do you need one or are you just thinking out loud? Are 35mm slides
still popular? If you're not seeing them maybe the technology isn't
calling for discharge illumination.

Just curious. Just repaired a Kodak carousel projector with 300W bulb
and wondered what the power requirement for a lumen for lumen equivalent
discharge lamp would be , or is it just smps gives the edge. But then is
there a problem with smps supplying a filament lamp, in the way of
thermal runaway

I think the technology is stagnant. Same goes for home movies on film.

There isn't sufficient need to improve the design.
