Query: Works but need plenty of sun

These lights are very bright and are doing what we wanted them to do. They do need plenty of sun light to charge up the batteries. We have them on the east side of our home to shine on the front porch. (2 each) The sun charges them and they work about 4 to 5 hours. It may stay on longer in the summer time. This would depend on the quality of the batteries and the design.//... Joe
