A photon-recycling incandescent lighting device

> useful light output

Part of what makes LEDs and neon lights feel so fake and sterile is that they give off visible light but no perceptible heat.

You can feel the heat from a 100W light bulb on your skin and you pick up on that subconsciously.

That being said, getting an even spectrum back would be a nice "improvement" (regression fix).

Personally I’ve always disliked feeling the heat of an incandescent lamp. And I’m fairly certain that one of the advantages of electric lighting over gas was the _reduction_ in heat produced while lighting the room.

And objectively this is again an advantage with LEDs. Yet, we still light candles today.

Speak for yourself, I don’t like candles for the same reason that I don’t like incandescent lights. Not to mention the smoke, the wax guttering and dripping everywhere, the fire hazards, etc, etc.

I bet you've just learned to associate the continuous spectrum from incandescent bulbs with the heat they also emit. Have you ever been in a space illuminated by sun tubes or skylights? Did that light feel fake and/or sterile?

That's the whole point. It's a learned combination of stimuli that (now, having learned them) belong together.
