I have a barn/shop that is in a rural area a few miles from my house. It's
in a very poor neighborhood so security is a concern. I have one of these
mounted on the front under the peak (probably about 15' up?) and another
ready to go up on the back when it's not -6 outside.

n_title?ie=3DUTF8&psc=3D1
I believe I put a round box up for it? I don't recall anymore as it was a
few months ago.
I intentionally point the heads pretty far down so they don't shine at the
homeowner across the street's house but they very easily illuminate the
drive/yard between the barn and the street, which is probably about 60'. I
also have a Wyze camera hung right next to it and it does a great job of
recording "events" when something triggers the motion sensor and the
light comes on. That usually means a half-dozen videos every week of cats
walking across the front of the barn at night... You do have to get within
about 20' of the barn to trigger the motion sensor on the lights. I'm not
sure if I have the sensitivity turned all the way up but it probably is.
For security lights I like the higher color temperature bulbs. They just
"look brighter" and the idea is for whomever triggered them to feel very
well illuminated.
Best Regards,
