The incandescent light bulb.

"In 1761, Ebenezer Kinnersley demonstrated heating a wire to incandescence."

I still don't think LED (or Halogen) house bulbs are anywhere near as good as the classic incandescent bulb.

Most LED bulbs give me a headache. Bad LED bulbs cause 'strobing' in my vision which is even worse.

I find Philips brand bulbs appear to have circuitry to "smooth out" the voltage and provide consistent light levels. I use my phone camera's slow motion mode to record my bulbs and see the flicker. Every brand I've tested via the above method, save for Philips, have suffered from flicker.

Give Philips a try? May just be worth the premium. Hopefully a standard like the one mentioned in a comment below is put into place.

I will, thanks!

There are LED bulbs this doesn't apply to. The flicker is so intense, damaging, and nauseating that people have tried to make standards to help get rid of it:

This isn't the LED itself. It's the circuitry running current through the light emitting material. Unlike incandescents and fluorescents where the medium itself smooths out poor signal from the circuitry, LEDs show you the quality of the signal going in.

Then there's the question of whether the color emission mix is designed so that your eye perceives it as an approximation of a blackbody spectrum. That's an issue of matching doping to our biology and one of those things that I think is just about settled in decent quality bulbs.

Once the doping mix and the quality of circuitry is fixed, the incandescent lightbulb is at best an historical curiosity.

I’ve gotten used to LEDs but I recently picked up an incandescent night light bulb- 25 watts for a dim glow. It gets really warm! 25 watts is an absurd amount of power. And people light rooms with multiple 60s! That’s bonkers

Love 25W bulbs for bedrooms. Perfect amount of light to provide a relaxed atmosphere.
