    You are aware of the breakdown voltage of the 1N4001 aren't you?

    Most tubes are now being replaced with their LED equivalents.

    If the 'tube light' is a standard fluorescent tube, how does that circuit generate the hundreds of volts needed for the strike-voltage?
    Having a 100W incandescent lamp (I-L) as the ballast seems very wasteful. Can you even buy such a 100W lamp in this day and age?
    The two caps store a voltage which is insufficient for the strike-voltage. Their only useful function appears to be to provide an AC path for the I-L. current. They act as voltage droppers, so the I-L voltage is less than full mains voltage.
