In areas of the country where electricity is cheap and heating fuel is expensive, taking the "waste heat saves heating fuel" phenomenon into account can affect the lifecycle cost analysis of incandescent vs the alternatives. In some rural areas serviced by nuclear power plants, the $/BTU for off-peak electricity is cheaper than $/BTU for heating fuel.

Well those bulbs are inefficient lighting devices and even more inefficient heating devices.
The bulb is actually 100% efficient at turning electrical power into light and heat. I mean, where else is the input power gonna go?
