I have bought many different solar lights previously from various suppliers, only to continually be disappointed at the minimal output of light. Well, these 40W lights are amazing! So impressed at how bright they are. It is hard to believe they are actually powered by solar if you would not know that. We\'ll definitely get more of these in this winter for a construction project as the cool weather and lack of sun in Victoria makes solar products harder to operate. We loved them so much. CAN\'T go wrong with these!!
