1、Motion Sensor: External motion sensor outdoor wall lamp adopts advanced PIR motion technology and IC lighting sensor. It will automatically turn on at 25% brightness at dusk. Once it detects movement, it will keep on 100%. After 2 minutes, no one is moving, and it will automatically turn off at dawn when the brightness is restored to 25%. 2、Default Auto Sensing Mode on Power Up: When the power is on for the first time, the maximum 100% brightness is maintained for 10S and then enters the automatic sensing mode 25% brightness. Once the sensor detects movement, the indicator light flashes slowly and continues to maintain the maximum 100% brightness. When the sensor detects that there is no signal (no movement), it will output 25% brightness after 2 minutes and then turn off automatically at dawn. 3、Switch to Manual Mode: If you want an outdoor wall lamp from dusk to dawn to provide strong brightness for several hours at night, you can turn on the wall switch for 0.5‑2 seconds "off/on" to switch from automatic mode to manual mode, then it will maintain 100% brightness for 8 hours. If it is night after 8 hours, it will automatically switch to automatic mode. If it is dawn before 8 hours, then it will automatically turn off and then switch to automatic mode. 4、Change from Manual Mode to Automatic Mode: If you want to change the manual mode back to the automatic mode forcibly, you can turn on the wall switch "off/on" for 0.5‑2 seconds, so that you can switch from the manual mode to the automatic mode. 5、Wide Range of Use: The wide bottom opening design makes it extremely easy to replace the bulb. The unique design appearance and weather resistance make it a perfect match for most outdoor scenes, such as gardens, porches, corridors, doorways, courtyards and other external areas.
