Peaktop 3601813B is a solar-powered light that automatically illuminates at night. It is designed to be positioned in direct sunlight to receive the maximum amount of sunlight and should be left in the "OFF" position for 2 sunny days to ensure the battery is fully charged before first use. Once fully charged, switch to "ON" and the light will come on automatically at night. The duration of illumination will depend on the amount of sunlight and therefore change received by the batteries. It features a 3.0V LED light and a rechargeable AAA NI-MH 300 mAh 1.
