I'd like to add a bug zapper in my garage. I have a duplex receptacle in the ceiling but it's fully populated by my retractable extension cord and door opener light fixture.
I have 4 T12 8' fixtures in the main portion of my garage within reasonable reach of where I'd hang the bug zapper. Is there any problem in mounting a handy box & receptacle on a knockout on the side? I really don't want the zapper on 24 hours so having it switched with the light would be great.
Fixture similar to this. Hard-wired into a ceiling box.
