I'm impressed with the solar charging and battery life of this flood light. I put up this flood light only hours before night fall and chose one of the 3 different modes this flood light offers. Not thinking it would have enough time to charge the batteries to last all night o was wrong and leaving my house in the morning before dawn, the flood light was working like a charm. Love it.. It lights up my whole driveway nicely and lasts all night. It feels solid and sturdy in construction. Very easy to install with 4 screws and anchors. Recommend this floodlight highly for the price.
