My house has over 300 LED bulbs… the only incandescent bulbs are in the ’fridge, microwave, and ovens. Also two wall mounted reading lamps on swing arms next to a bed. They use a funky hotdog shaped bulb that nobody makes a LED replacement for… plus, I never use them
As far as incandescent lights being good room heater, the really are not… particularly in recessed ceiling cans. Most of the heat goes up into the ceiling and provides little effective room heating. There is no forced air flow to move the heat where it can do some good.
Also, LED bulbs save you very little on your cooling bill. A typical air conditioner might use 1 watt of electricity to move out 40 watts of heat. So each LED bulb might save you 1 watt of cooling power… rather trivial to what the AC unit is sucking…
