They are very bright. I have daylight and can see beyond my property because of the brightness. You can see clearly at night. I have them all over my garden. The sensor saved me from setting the timer. Another light cannot shine too close to them as they turn off including other sensors. I had to return the entire order because my post lights were too close and were turning off each other. One turned on, then the other two went off, and for some reason it was dark enough and the other two turned on again, turning off the third. The whole night it went on and off in a rhythmic circle. To my surprise, my porch lights, two meters apart, worked together, and my wall lights on the sides of my single garage also worked at such a close distance.
