We installed four of these lights on a privacy fence that runs along a sidewalk on the front of our house. Out of the box, they stayed on all night. The low setting provided enough light for our application. They look amazing. They are a much better quality than solar lights we have installed in other areas. Being able to replace the the bulbs and battery packs was a significant selling point for me because I usually have to completely replace other solar lights after two or three years of use. They are beautiful.
Replaceable battery pack and light bulb.
Super easy to install.
ConsNone that I know of.
