I put on one my front porch, to light up the screen and front door for my daughter at night - lights up the WHOLE porch. I put one on the top step of a very dark and steep basement stairway - I can see all the way down the stairs. I put the last one in my sons closet - now I can see that it needs to be cleaned! They are very sensitive to motion, and have a high pick up range. I would guess it to be at least four to five feet - and 180 degrees at that! It will stay on for as long as it senses motion, and then shuts down about thirty seconds after you leave the area (saving the battery life). It is not adjustable, mounts flat to the wall (or where ever you are putting it)with one small screw. The design in the back allows you to take it off the screw when ever you need it to be portable. I took one to the chicken coop - light up a large area as I was walking in the yard and illuminated the whole chicken house. I am so impressed, I am buying three more. Will be great for the garage, the hallway, and the upstairs staircase. I can just imagine how handy they will be during a power-outage (I live in the North East - we get a lot of those). I know they have replaced my flashlight, rather than a single beam...they give of a 180 degree of light...GREAT..
