How to make a bulb holder? After you have determined the type of shade holder that your lamp or fixture has, you need to measure the fitter size of the shade holder. The shade holder fitter size refers to the diameter of the opening of the bulb holder through which the glass shade fitter passes.

The size of fixture-type shade holders and shades are, for the most part, standardized in North America and are found in several common sizes. Their fitter sizes and applications are as follows: 2 1/4 (electric-era fixture shades), 2 1/2" (gasolier shades), 3 1/4"(fixture & pendant), 4 & 5 (gas & pendant shades) and 6 (large pendant shades & hanging lamp slant shades).

How to make bulb holder? Interior Screw Shell:

Aluminum: Aluminum is the most common and cost effective material for the socket interior.

Brass: Brass is the most common materials in a socket shell. There are different finishes in the brass shell like; polished (shiny), antique, and unfinished

Brass plated: Brass plated shells are similar to the brass shells in appearance with a cheaper price. A brass plated shell comes with similar finishes to the solid brass shell.

Bakelite/Phenolic: These socket shells are thick black plastic and are typically found in less expensive lighting where the sockets are hidden by the lamp body.

Porcelain: The most durable and long lasting shell, porcelain is more heat and weather resistant than any other shell type. Where the light is outside or hangs with a bulb facing down, a porcelain socket is highly recommended.
