When I tried to install this PAR36 LED, I only noticed 1) off the holes was threaded onto one of the brass connectors. After threading the other hole with a 10-32 tap, it matched perfectly with the green ground screw I had in my electronics. So "homeowners" also get a 10-32 tap when buying this LED. In addition, the light is excellent and goes well with other PAR36 lights.
