Since this is “no stupid questions”, I will follow up with a question and demand that you not call me stupid: what about the lamp makes it “not food grade”? I assume that both salts are just NaCl, so do salt manufacturers put the salt through some process to remove dangerous contaminants or something?
You definitely can but its not food-grade so perhaps take that into account.

One contains some other stuff too, the kind that you don’t want to eat
Food is regularly tested for any poisonous/harmful contaminats. I would assume lamps don’t undergo the same quality control
