I had recently bought a pair of gate light of Hardoll due to the complication to fix a wired light at the area, actually it was an expirement to substitute solar light with the wired one and now iam fully satisfied with my decesion. The product is excellent in qulaity and performence. We ourself can install it very easily.Once you fix it and forget about it.It will function automatically and no headaches.The only thing you should care about is, it should be under direct sun light as the solar panel is installed above the light it should be exposed to open sunlight.
