light bulb powered stirling engine

read that light bulbs are extremely inefficient, 95% of the energy is turned into heat. Why not use this heat as a power source? Specially the larger spotlights generate tremendous heat. Why not "waist" it on something useful? Exchanging heat isn't complicated, I bet you could heat a bath or a boiler with a bulb and some patience. :-) Should be easy to build and test.
