Thanks for this explanation as it helps me to better understand your comments.

First most fluorescent ballast only produce around 600 volts to the tube not the thousands of volts you claim.

Second the surge protector is rated in amperage not voltage.

Third voltage is a difference in potential. The amount of current that flows is dependent on the amount of opposition to the push of the voltage and does not in any way define the difference in potential.
