Abstract
A tempered glass globe for a hazardous location luminaire comprises a bowl portion and a flaring rim portion with the walls substantially uniform in thickness in both portions. The rim portion makes an angle of taper with the vertical in the range of 15.degree. to 45.degree. and defines a section of a conical surface for making a nonflame-propagating joint with a mating conical surface in a globe ring. The outside of the flared rim may be ground for sealing directly to an accurately machined metal surface.
