These came as the supplied lamps in a 1977 2x20 preheat shop light fellow LG member VeryHighOnOutput sent me recently, thanks again! For Altos, these actually appear to have quite a bit of mercury content, and fairly thick phosphor, both things Altos are sometimes known for having less of than they should.

These would be my first F20 Alto lamps; I have cases' worth of the F40 daylight deluxe Altos in use back home but I've never had any short Alto lamps prior to this.
