WebAug 20, 2013 · Keith brought up a really good point. He’s actually right about lighting only lasting a milli second. That would actually bring ur calculation to somethin like 2.7 x 10^4 or something. Either way, i think a lighting bolt only has enough energy to power on 1 single lighting bulb, for 3 or 4 months. The amperage just isnt there….
