Is a lighter effective because it’s on fire? Or just because it’s hot?
If you made a lighter that was just as hot as another lighter, would it work just as well even if it had no fire?

I have an electric lighter that we use for lighting candles. It charges via USB and generates a short spark between two contacts to light the candle.
