Lightning is one of Nature's most dangerous phenomenon. The average lightning flash could light a 100 watt light bulb for more than three months. The temperature of a lightning bolt may reach 27.760°C which is hotter than the surface of the sun.
Lightning is not only an outdoor hazard. In houses without adequate lightning protection. It can be dangerous to take a bath or shower. The electric shock could be delivered along the water pipes. There is also the risk of lightning shocks being transmitted via telephone or plugged in electronics in houses without protection. Thus, people who live in these houses should unplug telephones, computers, and televisions during storms, protecting them from damage in case of lightning strike. If that is too much work, it's much safer to at least install special socket inserts that protect against surges.
