Bulb manufacturers designate incandescent light bulb shapes by letters, and all of our globe light bulbs are of the round "type g" variety.

The IG9536 is a smaller version of the IG0159, and while globe light bulbs work well with fixtures like the Burlington and Glenbrook, they don't fit most 2-1/4" fitter glass shades.
