Specifications: Adaptive to filament, electricity saving lamp. This lamp is internal equipped with auto body sensor. If people come, the lam will power on and if people leave, the lamp will power off. Inner body auto sensor adopts infrared heat releasing device, and it can accurately capture moving low frequency signal and automatically power on. When people leave,the lamp will auto delay power off,convenient and energy saving. Inner side of the lap is set up with auto ambient brightness detecting circuit. Only when ambient brightness is lower than setting value, the sensor will receive sense and let the lamp power off. Item Name: Motion Sensor Rated Voltage: 220V 50HZ Output Way: Controllable Silicon Load Power: Filament Lamp 100W, Electricity Saving Lamp 30W, LED 18W Delay: 20s (People are moving within the sensing range, the switch will auto delay and keep connecting. If people stay still,switch will stop responding.) Sensing Distance: 3m - 6m (High temperature will influence switch sensibility.) Sensing Angle: 110 Sensitivity to light: Darkness Features: DIY Installation, Light Detector Switch, Energy Saving, Universal Size: 46mm x 20mm/1.81" x 0.79" (Approx.) Punch: 38mm - 40mm/1.50" - 1.57" (Approx.) Notes: When installing,please disconnect the power to guarantee safety. Don& 39;t apply it to overpower current or voltage. Don& 39;t install it accessible to water. Detection distance will change according to ambient temperature& 39;s difference. In summer, detection distance is short (it is obvious when close to human body& 39;s temperature). While in winter, detection distance will be far. Don& 39;t install it in lower than -20 Celsius or higher than 60 Celsius. Don& 39;t expose it to sun. Don& 39;t install it in which there are moving objects. The first time power on, there will one minute initiation;during this period,the device will shine,it is normal phenomenon In coast zone, thermal flow will trigger the sensor because of ocean current. If installing filament lamp which emits great heat, please keep far away from the sensor. (at least 1m) Due to the light and screen setting difference, the item& 39;s color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Package Included: 1 x Motion Sensor
