I don’t use incandescent bulbs mainly because they emit a lot of infrared heat. When I want to light up a room, I want light not extra heating. Using them would just make my air conditioning work harder. I also dislike their 2700 K color temperature. To get something closer to daylight, you’d need extremely high-wattage bulbs, which only generate even more heat since they’re so inefficient. As for the idea that fire is “biologically compatible”. I don’t see it that way. Life didn’t evolve around firelight. Fire is destructive to most life: it burns, kills, and destroys. The organisms that thrive near volcanoes do so because of heat and chemical nutrients, not because of the flame or light itself. And then there’s the lifespan. I can’t stand how short incandescent bulbs last compared to modern alternatives. That’s why I prefer high-quality, well-designed LED lighting. LEDs give me brighter, more natural light options, use a fraction of the energy, and last far longer. They also make my home less dependent on the grid since I use less electricity, it’s easier for me to generate, store and use what I need myself. When i remember negative parts of my childhood, low lit orangy colored rooms at winter are something that stuck with me. And burned fingers when light dies and you want to change it quickly..... This is how we do lighting in our house: Picture taken at winter day.....low daylight (cloudy day) can be seen in room down the hallway and as "blue" reflection on wall that is opposite to a camera next to a wooden doors. This kind of light simply brings you up in those dark and almost dead winter days. Long live Shuji Nakamura!
