LUMEN LED is a unique, modern nightlight. Simply set a duration and turn it on. LUMEN LED will automatically turn on every day at that time and will turn off after the set number of hours. Lumen should be placed on a shelf or mantle in front of a light colored wall. Lumen works best in low light. The farther Lumen is from the wall, the larger the cast shadow.  LUMEN LED uses 4 AA batteries. LUMEN is designed and assembled in Brooklyn NY USA.
