Light bulbs are very efficient heaters; they convert almost all of the energy they use into heat. The only losses are the light that goes out your window, and that gets converted to heat too, just not inside your house.

Not really true. Lightbulbs are very efficient at generating heat, but not at heating your house. Most of the heat is in the bulb/fixture itself and the air surrounding the bulb. A very small portion of it will keep you warm while you're sitting on your couch watching hockey, which makes heating your house with a furnace or hot water more efficient.
