SunLike is the OUTBEAM brand solar lighting system dedicated to pathways, though Cegonia also works well for this application. They are easy to install and require virtually no maintenance. The battery is protected with a 5-year warranty in the US.
Their smart power technology provides up to one week of autonomy from one full charging, meaning your pathway lights will continue to function at 100% for 7 straight days of cloudy or inclement weather. These lights also eliminate the need for costly trenching or wiring.
