Solar Welcome Stone - Lighted Butterfly on one side, lighted Dragonfly on the other The Solar Welcome Stone has been designed for outdoor use. The solar module in the upper part converts sunlight into electricity, which is then stored in the integral rechargeable battery pack. The light switches on automatically when it gets dark and turns itself off when it gets light or when the battery is full discharged. The source of light comes from two super bright amber LEDs (light emitting diode), which provides bright light but uses very little electricity. In order for th elight to operate, the solar module needs to be placed in direct sunlight. The performance of the light e.g. the charging of the battery depends on the season.
