Personally I love the heat that an incondecent bulb emits, I can actually keep my hands warm on my keyboard while lowering my room heat. 75 watt bulb with heat

  Depending on where you live, the energy “inefficiency” of a light bulb is no such thing. In the UK, for example, during winter (and spring and autumn) the heating is appreciated! However, it is 2-3x more costly than using gas central heating. (However however something something whole house vs room-specific heating.) In the summer, it’s a complete waste though. Directed infrared heating panels may be the most efficient because they do what you describe - heat you up directly, rather than heat the air in the room.

    Electric powered heat pumps (essentially air conditioners run in reverse) can have considerably greater efficiency than electrical resistance heaters. https://en.wikipedia.org/wiki/Heat_pump#Performance_considerations https://en.wikipedia.org/wiki/Heat_pump#Performance_consider...

    It's also heating the ceiling, which will reduce the efficiency further. It's a straightforward issue of separation of concerns, there are some occasions where you want heating and lighting always tied together, but they are niche. Almost everywhere in the world you have large periods of the day or year when you want lighting without heat.

      I use a desk lamp so It's really close to me and I get both the light and heat and I swap the bulb out for an LED during summer.

        Ah, I see, that’s a good idea.

  There are far infrared heater bulbs that just emit IR and don't get too hot, so you can keep them on the desk without distracting light or getting burned while also keeping power consumption low. It separates the light and heat concerns.

  They're also way easier on your eyes. And they don't flicker at high speeds that make everything look framey.
