Spotted some gumball/shoebox hybrids at a arena in Toronto. These might have orignally been MV but they currently use MH. 175w from my guess. They use a similar glass refractor as the McGraw Edison mini gumballs.
IMO it doesn't really seem like Overkill.....even though i'd expect something more along the lines of a Wallpack/Floodlight....or prehaps a bucket style Area Light (Nema Head or Not)
