We usually have to rely on mains powered lights at Christmas time in the UK because of the lack of sunshine, but these Endurance solar icicle lights are designed to work in winter. As long as you locate the powerful 300mAh polycrystaline solar panel facing south, or as near south as possible you should get some LED christmas cheer without running up your electricity bill. And even if the sun decides not to show itself at all, you can simply detach the solar panel from the light string and bring it indoors (no need to take down your lights) for a quick charge direct from your computer, as it comes with a separate USB charger. Another great feature of these lights is that you can switch them on and off simply via the panel, so you can choose to switch the lights on when you want and not have them come on automatically when the sun goes down at 4.00pm in winter.
The length of illumination is 1.7m long with 17 strings of icicles that dangle down each having 6 LEDs. The length of each icicle (stretched out) is approximately 43cm.
