Good find! If I used these in an outdoor fixture, would they have the same 60F minimum start temperature as other energy saving lamps? I read that T12 VHOs use a neon or neon-argon fill mix. Anyone know what these use and the low-temperature implications? I want an old gas station fixture someday and wonder if PG Miser lamps work well in these fixtures in the winter.

I think most of the service station lighting used the 48 inch and 72 inch long PGs.
They were used in cold weather locations, but were used in an enclosed fixture for cold weather use.
They were even used in street lighting for many years.
I would guess the Watt Miser would have the same cold weather starting temperature since they are of the rapid start design with the continuously heated filaments, but mot sure.
I was told that the 96 inch PGs were used mostly for high bay lighting in warehouses and factories and other high ceiling interior applications.
Maybe a member here can clarify this.
