I bought this spotlight unit to light my path when I take out the garbage at night. I mounted in high on the corner of my house where it gets good (though not great) sunshine, and it does exactly what I hoped. It has a middle light and two swivel spots, one on each side, that can be positioned to light up a broader area.It always lights my way quite brightly, even after cloudy days. It actually stays on dimly until it detects motion, and then turns bright until the motion stops for 30 seconds. I cannot say with any confidence how long it stays on during the night, since I rarely get up before daylight. But it does continue to work well into the evening (perhaps much longer on sunny days than cloudy ones). I think the always-on feature is nice for security purposes, and I don't think it is really bright enough (until it detects motion) to bother anyone.I'm very happy with this unit and impressed at how bright it is and how consistently the motion detection works. Also, given its position high on the house, it is nice to know that I won't have to climb up periodically to change the batteries, since it is solar operated. I suppose the rechargeable batteries will run down eventually and at that point I will just have to replace the entire unit. But it is inexpensive enough that I'll be happy if I get a couple of years use out of it.
