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.
- darkpuma 8y agoElectric 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...
- Brakenshire 8y agoIt'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.
- foxhop 8y agoI 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.
- Brakenshire 8y agoAh, I see, that’s a good idea.
