Lightning surge protection
Most surge protectors are made to handle 'transient events' caused by other devices in a power distribution system, such as an un-controlled voltage spike from an improperly switched inductive load (or a related switch failure).
A 'direct hit' from a lightning strike cannot be directly 'stopped,' neither can any consumer-grade surge suppression device (at least none that I'm aware of) fully 'handle' the power of such a surge without catastrophic failure of the device, and likely damage to your electronics.
The proverbial 'first defense' against lighting damage to your equipment should be the use of external lightning ground-path protection, such as installing 1/more lightning rod(s) which reach above the highest point of your incoming power line (providing a more likely 'target' for the lightning current to 'strike' in order to reach ground without going through your home wiring).
After taking sufficient measures to avoid 'taking a direct hit,' you can use consumer-grade surge suppression devices (like the ones you're asking about) to provide an added degree of protection to your devices, to lrotect against capacitively, or inductively coupled surges joining your wiring system from wires that run near the path a lightning current took to reach ground.
