I'm having trouble with the term "lamps". I'm taught that in the lighting industry we use that term to mean the light bulbs that we use in our fixtures. But whenever I say lamps, my customers get confused and think I'm talking about a table lamp or a street lamp post. Should I just go back to using the term "light bulb?" This is annoying. Especially in emails. People sometimes don't get what I am talking about when I say I'm going to replace their lamps or use a lamp with a different beam spread.
