The lamp arrived on time and work great. They are solar powered, and when I received them, I flipped the on switch in my living room planning totake them outside to charge. I got interrupted and forgot to take them outside to charge.  That evening I went downstairs and noticed that they had charged and were glowing brightly in the living room.  It's been about 3 days since and these lights are still in the living room and glowing every night. I am thinking about putting them on my fireplace mantle and buy two more to go outside. I couldn't believe they charged just ffkm the daylight coming through the living room window!
