The light remains continuously on, regardless of motion or ambient light conditions. - Mode 3: Always Off Mode
The light remains off.
Brightness Adjustment:
In Always On Mode, you can adjust the brightness from 5% to 100% by pressing and holding the control button. The light has a memory function that will recall your last brightness setting when you switch back to Always On Mode.
