I got some lanterns with mercs that were installed on PSMH gear....
This one from a recessed can in a library

The glass of the stem press on the outer lamp had electrical breakdown and it meltd off like an EOL fluorescent on Instant Start.... The frame with the arctube (arctube is intact) are just laying loose and disconnected inside the outer bulb, scratching off the phosphor
