I've noticed than many lighting related companies end with "ram",
For example: Osram, Tungsram, Volfram, Luxram.
Is it only because of the 2nd name of the tungsten element (wolfram) or is there another reason?

pure guess but to sound like - related to one of the other companies

he name is derived from osmium and Wolfram (German for tungsten, also used in English). Both elements were commonly used for lighting filaments at the time the company was founded.
