Bayonet bases or caps are often abbreviated BA, with a number after. The
number refers to the diameter of the base e.g., BAU15 is a 15mm (0.59") diameter
offset bayonet base bulb. The lower-case letter s specifies that the bulb has
a single contact on the bottom of the base. The BAU15s base has one
contact on the bottom and two offset (staggered) lugs on opposing
sides of the base.
