Have been threaded into the center of razor wire wall mounting of our house in Central America several these light tubes. They do not shine very brightly, but are clearly visible at night. Unfortunately, the solar panels are covered with plastic instead of glass, so they are always murky over the years and thus can load less sun in the battery. Therefore I have to replace all 14 months each hose. Pay at the next reinstallation times thin glass panes on the cell glue. Although this reduces the amount of light a little, but should slow down the aging process of the plastic disk a lot. So if you should even replace the disc against a glass there of my five stars.
