LEDs are nice and bright. They seem to turn on with any wildlife larger than a cat (like a racoon, a dog, deer ... snowmobilers..). I'd have preferred an adjustment for sensitivity, but that's being picky! They got the sensitivity pretty close to perfect.
They are installed at our cabin. The first one is aimed to see our vehicle arrive and lights up our drive to the shed. The second is above the cabin door and I no longer worry about tripping over toys the grandchildren left about. I can now see to put the key into the door. The last one is on the deck and faces the trees. As someone else mentioned, the motion of the trees does not turn on the light.
The lights start to work just after the sun goes down and stop working a few minutes after sunrise. Perfect.
I don't have any issues with moisture since the lights are installed beneath the overhanging roof of the shed and the cabin.
It has not been cold enough yet to give them a good test. I know they work down to -25C (about 15 below F). I'll update the review (If I can figure out how) when it gets colder.
