IR will do nothing. The energy per photon is to low.
However, UV contains more energy per photon an even more the shorter the
wave length is.
An ordinary ('blacklight') LED is insufficient in case of hard ignition.
Better to het short wave UV LEDs. Disadvantage is that the price raises
exponentially to the reduction factor of the wavelength.

Thanks, I understand. Well I don't have a very high voltage in the Clocks...
but it is a method - yes.
