Beautifully designed into a traditional Mason storage jar, the Finelife Solar Jar Light will add colorful light to your garden, patio, window sill or anywhere you want to place it. At night it lights up automatically and in the daytime it charges while outside or in a sunny window. A switch under the jar’s lid lets you choose between warm light and cool light. Inside the frosted glass jar is a highly efficient solar cell, rechargeable battery and LED lamp. When the jar is placed in sunlight, the solar cell creates an electrical current that charges the battery over the course of the day. This energy is then used at night to power the LED lamp inside the jar. The light emitted is diffused by the frosted jar and gives the appearance of sunlight.
