Bought four of these about a month ago to light up a driveway and I must say Im impressed. I got these pretty much near dark, but I hooked them up in the dusk to dawn setting and it worked like a charm. It was bright and lasted the whole night without a bit of sunlight. Ive also tried the motion sensor from dim to full brightness of these solar panel street light and its still working like it should, We have a lot of guest so i know this product is quality.
