Sunna Design Solar Powered Lights

Solar powered lights use photo-voltaic panels to convert sunlight in to electricity. This electricity is stored in one or more batteries for later use. A Sunna Design  solar light matches a NiMH battery that has very high temperature resistance, with the Sunna-core that manages all the functions of the fixture. This smart system allows the Sunna Design light to adjust the light output slightly to avoid a blackout condition. The Sunna-core also logs performance data that can be downloaded via Bluetooth to the Sunnapp.
