2. Tap the ▶key to select a higher color temperature setting, or tap the ▶key to select a lower one. You can select from 8 color temperature settings: 6500K (daylight), 5700K (cool white), 5000K, 4500K (neutral white), 4000K, 3500K (warm white), 3000K and 2700K (soft white).

If the power supply is suddenly interrupted, the light will automatically return to its settings before the power outage when the power is restored.

• If the light was on before the power outage, it will automatically turn on when power is restored, and restore the brightness and color temperature settings before the power outage.
• If the light was off before the power outage, it will remain off when power is restored.

Turning On/Off the Presence Detection Function

50cm 60±10cm

The Presence Detection function allows the light to turn on automatically when the user enters the detection area (as shown in the figure).

Illustration of a hand pointing at a touchscreen device with icons for brightness and saturation (no text or symbols)

• To turn on the Presence Detection function, tap the Presence Detection key. The Presence Detection indicator will light up.
• To turn the function off, tap the Presence Detection key again. The indicator will go out.

• With its ultrasonic sensor 50~cm above the desktop, it detects at 60 ± 10~cm in front of the screen and has a conical detection shape.
• When the Presence Detection function is on, if the user leaves the detection area for more than 5 minutes, the light will automatically turn off to save power.
• With the Presence Detection function on, if you manually turn off the light, the Presence Detection function will be disabled temporarily and the Presence Detection indicator will flash for about 30 seconds. When the indicator stops flashing, the

Presence Detection function will resume and the light will turn on if you are still in the detection area.

• Do not block the ultrasonic sensor on the light. Otherwise the Presence Detection function will not work properly.
• Do not insert any object into the ultrasonic sensor to avoid malfunction of it.
• The presence detection function operates based on motion tracking. If users maintain a fixed posture in front of the screen for more than 5 minutes, such as when watching videos, it may cause the sensor to detect no movement and subsequently turn off the light.

Ultrasonic sensor

- The ScreenBar Pro light uses an ultrasonic sensor to detect presence and absence by emitting high-frequency sound waves and analyzing reflected signals to determine object distance and movement, enabling automatic light control. However, environmental factors such as temperature changes from heating or cooling devices or frequency vibrations from humidifiers may affect detection accuracy, potentially causing unexpected light activation.

My Favorite Mode
