Haha, no, "Lightning" is the name Apple gave to one of their proprietary connectors. It's on iPhones, iPads, and maybe a few other Apple devices. So this particular port/7-pin weird cable allows you to connect the keyboard to your Apple device.Ehr - what?
A 'lightning connector'? Are you referring to the sort of lightning that zaps down from the sky during a thunderstorm and kills people, or damages trees/buildings.
Maybe you mean 'lighting'? To do with lights. I guess a LOT safer on a keyboard??
