I've been looking on line for the evolution of the light bulb and a catalog of the different types and wondered if anyone happened to know of a handy source.
I've found out a few things, such as the number after the letter classification tells you the highest width in eighths, such as a T-8 is equal to 1", an A-19 is equal to 2 3/8's inches, but I thought there might be an all inclusive sight around.
