What a stupid question! "Gaffer tape"???? Need to use metal cable ties now, keep up with the regs!!!
As for lights? You should go for 6 x 500w sodium floodlights. That extension cord will be ok, I think?????
Nowt wrong with Gaffer Tape.
It's been fixing things from broken microphone stands through Roadies ripped jeans to burst truck radiator hoses, shredded fan belts and anything and everything between for decades and will still be doing so long after the new fangled metal cable ties have rusted into oblivion!
