Flamme Rak is a white plastic candle with our natural Flamme flame. This light fits just as well indoors as outdoors, in a lantern or in a group with other outdoor lights from the Flamme family. This electric light can be used both with a light sensor and with a timer. If you want a sensor, set the switch to the ON position, the light then lights up when darkness falls. If you put the switch on a timer instead, the light stays on for 6 hours, then it goes off for 18 hours and lights up again the next day.
