Instead of arguing the point I simply said thank you and requested a return back to Amazon. These lights with halogen bulbs illuminate the entire interior of our parked cars! Nice and bright with good coverage.
I purchased two of these lights 3 years ago. Can I purchase just the sensors to repair? I don't know but suggest you check the RAB web site. Can this fixture be directly mounted to an existing standard outdoor weatherproof surface mounted round box? Yes, that’s how mine is mounted. You a traditional surface mount box that any security light would mount to.
