The natural electrical insulating properties of glass are utilized to create a light socket that allows the electrical components to be seen--yet safely protected. Like a piece of fibre optic cable, the glass light socket traps the light from the bulb and bends it upwards to transmit a small bit of light at the top of the socket. Hand Blown Glass Socket with 14' of Cloth Covered Cord + Plug. 40 watt maximum E27/26 bulb (not included).
