The sleek design of the Pyramid solar vinyl post cap will light up your deck, walkway or patio in style. The Pyramid Solar post cap contains 4 high output LED lights. The solar energy collected during the day is stored in 2 AA Ni-MH rechargeable batteries and converted into light at night. The length of time that the lights stay on at night (up to 12 hours) is directly proportionate to the amount of sun exposure received during the day. Only available in white.
