Wow! That's an interesting failure I have never seen before as described.
Lamp ceramic looks a bit old and discolored perhaps by way age or from rapid gas escape. Either could do similar. Not familiar with any single ended capsule halogen capsules inside a PAR 64 lamp. This is a really odd concept for me... why? Lamp engineers spent many years in the 60's in developing a single ended halogen lamp. Later the 120v halogen PAR 64 lamp concept as upsised from PAR 56. This PAR 64 lamp operates best with a dual ended capsule lamp capsule from the early 70's, in spinning the bottle.
Capsule is not innocent - do I see failed "Getter" in smoke ring above it, even if not itself blackened? What's a Getter doing in a PAR 64 lamp? What's with a single ended PAR 64 lamp capsule in a lot of work to make it single ended, - perhaps a "Base Up to Horizon" type problem created failure problem?
This is an alien failed lamp you should save as best possible for Mark from Osram. Put on hold a year or two for .... time and funding to be free'd up so this lamp example can be sent back to the engineers. Not like this question is a rush - more a curiosity.
I have a note about a Thorn GFF lamp existing. One would think Ansi code lamps would be on-line. FFP is troubling but if the basic standards of FFP, it would qualify. Single ended... why?
