This is an energy-saving light with an integrated photoelectric sensor and movement sensor in the middle, to control light activation only in dark or low light conditions. When it's dark and detecting any movement, it will automatically keep the light for 30 seconds, and then will turn off by itself. If it's NOT dark, the light will NOT turn on with any movement. WHEN PLUGGED-IN FOR THE FIRST TIME, IT MAY TURN ON WHETHER IT'S DARK OR NOT. PLEASE ALLOW IT TO BE SELF-PROGRAMMED AND TO COMPLETE THE FIRST ON/OFF CYCLE, AFTER WHICH IT WILL TURN ON ONLY IF IT'S DARK. Taking into account the average use of such lamps, it yearly energy consumption is less than 2KWH/Year, almost 95% energy saving compared to a standard bulbs, which really makes sense for such a bright night light. This model contains 25 LED chips, and has a total power of 5 Watts. Each 1 Watt is bright enough to provide around 80 lumens, and the total output comes up to 400 lumens.
