You’ll see lots of lightbulbs
Sometimes a light bulb is just a light bulb. I made these high intensity short-arc mercury-vapor lamps used to micro-photolithograph masks onto silicon wafers before depositing the metal in a vacuum, firing the metal in a glass lined furnace, chopping the wafers into "chips" and soldering the leads to make "computer chips." I worked beside the glassblower that patented these lamps at his shop in Santa Clara, California, or, if you prefer; Silicon Valley.
