>At a specific temperature, using specific materials.
The temperature of incandescent bulbs is directly related to the light that they give off, and tungsten is the obvious best material, there's no other materials on the horizon giving an improvement for the tech. It really is a pretty well understood tradeoff surface on a very mature technology (which was then displaced by completely different ones).
