With a "lightbulb company", I was just using a rhetorical device of describing something in banal and obvious adjectives to the average consumer to contrast it with something non-obvious.

E.g. The "hamburger company" McDonald's is actually one of the largest real estate holders that makes more money from land rent than food. Adding later clarifications of "McDonalds sells more than just hamburgers such as salads and eggs in English muffins" isn't necessary for most readers.
