Light bulbs get hot ! The heat is not a desired effect, and the light bulb is not very efficient, if you selected a light bulb to serve as a source of light.  But if chose a light bulb to use in a place where you need heat, then the heat you get from it is very desirable, and the light bulb is very efficient.  It all depends on your point of view.
