I have a tennis and basketball court outside. Well...someone took the lights down at some point. It was buit in the 30's so they are long gone. There are 4 poles. Anyway, I ran a new 220V/40A supply out there and cant decide if I should go halogen or metal vapor. Does anyone else have a court and know what type of lighting you have? i thought about 4 metal vapor or 8 halogen...not sure what is brighter.
