- Long Press Button: Press and hold the main button to turn the light ON or OFF.
- Short Press Button: Briefly press the main button to cycle through the detection modes:
- Always-ON Mode: The light remains continuously on.
- All-day Motion Detection Mode: The light turns on automatically when motion is detected, regardless of ambient light conditions. It turns off after approximately 30 seconds of no movement.
- Night Motion Detection Mode: The light turns on automatically only when motion is detected in a dark or dimly lit environment. It turns off after approximately 30 seconds of no movement.
Motion Sensor Functionality

Image: Motion Sensor Range. This image illustrates the effective range of the smart motion sensor, covering a 120-degree wide angle and detecting movement up to 10 feet (3 meters) away.
The integrated PIR motion sensor has a detection range of up to 3 meters (10 feet) with a 120° wide angle. Ensure the sensor is not obstructed for optimal performance.
Color Temperature and Brightness Adjustment

Image: Color Temperature and Dimming. This image shows the three available color temperatures: Warm (2800K), Mild (4500K), and Natural (6500K). It also illustrates the stepless dimming feature, allowing brightness adjustment from 10% to 100%.
- Change Color Temperature: Single press the dedicated color temperature button (often marked with a sun icon) to cycle through Warm (2800K), Natural (4500K), and White (6500K) light.
- Adjust Brightness (Stepless Dimming): Long press the dedicated dimming button (often marked with +/- or a brightness icon) to smoothly adjust the brightness level from 10% to 100%. Release the button when the desired brightness is reached.
