Surge protection(Kinda) with a power bar
A power strip will not be able to fully protect your equipment just turned off with a direct lighting strike. The switch contacts are only a few 1/10's of an inch apart. How many miles did the lightning travel prior to the strike? Turning the switch off will keep the equipment safe from most transient spikes caused from lighting and switch gear transfers. There are small surge suppressors that can be added to the outlet prior to your sensitive equipment that will help reduce the spikes but a direct strike will fry them in hopes of saving other equipment. like this many of the power strips have less than 150 joule capacity, the model above is 600 joules but the cost is higher.
