This is a bit of a trick question! It plays on the word "bright" which can mean two different things:

* Brightness as in light: Dwarfs are much smaller than the sun and produce far less light. They are not inherently "bright" in this sense.

* Brightness as in intelligence: This is where the saying "small but mighty" comes in. The term "dwarf" often implies intelligence or cunning, not literal size.

So, the answer is: Dwarfs are not actually "bright" in terms of light. They are often associated with intelligence and wisdom, which is a different kind of "brightness."
