I need help identifying the proper nomenclature for sealed beam bulbs
of various sizes and wattages. I have several hand lights that I
would like to convert from the old hard to find six volt screw post
batteries to the newer twelve volt type. I just don't know the proper
nomenclature for a twelve volt sealed beam lamp that is three and a
half inches across and is connected by screw terminals on the back of
the lamp.
