24k Collection NightlightsI make these nightlights with 24k gold lustre and chose a dark background to set it off with high contrast. I add hand painted details after removing it from the kiln. Each 1 comes standard with a manual on off switch or an optional automatic sensor which will turn the bulb on when the room is dark and off when it is light. This feature offers convenience, is energy efficient and operates best when placed near a window. A 4 watt bulb is included.
