Although the lights are beautiful and heavy duty they are very dim. I have had them now for just 2 years and have replaced the solar batteries with the same kind of solar batteries 3 times. You shouldn't have to replace solar batteries like this. Other less expensive solar lights in my yard are 6+ years old and no battery replacement so far. They get full Arizona sun and do not stay on more than an hour tops. Very dim lights. I have even cleaned the solar panel with just watering case they were dirty. This did not work. Very dissapointed.
