I don't believe there is a surge protector out there that will protect you from a lightning strike. A bolt hit our 4 foot wide brick chimney one night, and blew it to smithereens. We lived in the suburbs in MI at the time. The brick shrapnel dented the garage door across the street, and 100 ft away! Everyone whose property bordered ours lost some appliances. Everything electrical
that was plugged into the wall, including our surge protected computer was fried. Ours, and all our neighbors lost their in-ground sprinklers. The gas meter which sat near the chimney, was knocked off the gas pipe and natural gas was shooting up into the air 6" from the house. Thank God the phone worked. The gas company was there in a New York minute to cap it off. All told, damage to our home alone amounted to nearly $20K. Those were 1990 dollars.
Our Electronics and Commo guy told me that the surge protectors you buy for computers protect you from power surges and outages, but not lightning. I believe him.
