nope it was a style in the late 70s and early 80s I remember seeing those ALL over when I was a kid in the late 80! I loved those classical 70s-80s style, they had them in cylinder shape too!
The Denny's restaurant here was somewhat dated until a recent remodel. It had these, both in recessed and non-recessed versions all over inside, as well as some large greening merc lanterns in the parking lot.
I know of a subway station with the recessed versions of these, they look like they could have been MV and were probably original to when it was built (1987).
Incandescent for indoors most of the time...usually I believe PAR 38 lamps and some regular A-19 shape incandescent
