These LED solar string lights are amazing! They use no electricity, since they are recharged by the sun. Optionally, the battery can be recharged via a USB cable. They are easy to hang using the included hooks. There are several brightness settings and lighting modes that can be toggled, using the remote control. I mounted my solar lights to the brick wall on my deck. The provide more than sufficient lightning for dinners at night on the deck. I highly recommend these solar led string lights! #Solar #LED #Lighting
