The A15 bulb is 158 in (1 78 in; 48 mm) wide at its widest point.

What does the a in a19 stand for?

A19 refers to the shape and size of the bulb itself. "A" stands for Arbitrary -- just the name of the shape that's familiar to most of us. "19" refers to the size -- in this case, 19/8" (or 2 3/8") across. E26 refers to the type and size of the base -- the part that goes into the light socket.
