This is a solar product and it requires sunlight to be powered. The length of time these stay illuminated depends on the time of year and weather conditions. They will still work in winter but only for a couple of hours from dusk. Approximate lighting times are: Spring = 2 - 5 hours, Summer = 5 - 8 hours, Autumn = 2 - 5 hours, Winter = 0 - 2 hours. Expect the brightness intensity to fade as the battery charge becomes low.
