It varies intensity as well.
If a white LED is wired in series with a simulated candle LED will the white one flash randomly like the candle?
Short answer is no. A white Led typically uses 4-4.5V to run. The Yellow LED would be about 2.5V thus two would be 6.5-7V minimum. The tea candles use a 3V coin battery which is enough to light the LED. A transistor is series varies the LED voltage thus flicker.
You would not want to increase the battery voltage as it most likely fry the little encapsulated microprocessor or whatever circuit creates the random flicker (I also read that it could use a long count chain counter that feeds back on itself in pseudo random fashion to create flicker).
More info than you wanted.
