Last season a friend and i used 2 heavy duty lights (with 2 25m extension cords) when what we were hitting didnt have a lamp post nearby, but obviously not having a generator, finding power was pretty impossible, unless you'd go to the owner of the house and ask him for power for some light to grind his fence (altho we did plug it in a church once, worked nicely).
So apart from getting better lenses, do you guys have any good ways to light up urban (cos last year filming with my friends canon 60d with a regulat lens, tye footage wasnt really enjoyable due to a lack of lighting)
