The scene takes place at night at an old neighbourhood in santiago de chile. The action ocurrs on the street were two guys discuss. The hmi is located at the roof of a 5 floor building. From that point in a straight line to the action it might be 30 meters( 98 feet)
The thing is that I have never photographed such a huge place at night, so I have some troubles with the right watage(wats) to use. I was thinking in using a negative stock kodak vision 250D.

Hi,

If you look at www.arri.de they have a photometric calculator. From looking I think a 6k Arri PAR could give you a T4 with one of the wider lenses. Speak to your gaffer, if you dont need a wide area or coverage a smaller lamp would work.
