GE Automatic Night Light

120V, 4w MAX. On at dusk, off at dawn. 4-Watt bulb included. Use only GE 4-watt, clear, cool-burning type C-7 replacement bulbs. This a is polarized device. It has a polarized plug (one blade is wider than the other). The polarized plug is not intended to be used with nonpolarized outlets (where both slots are the same size). A polarized outlet is intended to fit with a polarized plug in only one way - the longer slot with the wider blade. Note: Bulb may flicker at certain light levels for a short period of time. This is a normal part of operation.
