This may actually have 120 volt tap......some of my streetlights can do 240 volt when wired differently...note the tag on this streetlight said "Wired for 240 volt" which its possible it may have 120 volt feature.....he will need to look at the diagram...
It is possible to run a 240 volt light off of a household voltage 120 volt if it has a two wire set up assuming that it has a hot and neutral wire set up, I've done that before with 240 volt lights.
I had a 240 volt streetlight with a three wire set up two hot wires and a neutral wire and unfortunately you have to run those off dryer or stove outlets.
I would like a bracket like on this powerdoor or my M-400 a2. I dunno why some M-400 a2 powerdoors have brackets that hold the ballast and others just screwed directly in the powerdoor.
