Setup and Installation

The BLS Under Cabinet Light features a simple, wire-free installation process using built-in magnets and adhesive strips.

  1. Prepare the Surface: Clean the desired installation area thoroughly to ensure it is dry and free of dust or grease.
  2. Attach Magnetic Strips: Peel the protective film from one side of the adhesive magnetic strip. Attach this side firmly to the back of the light fixture, aligning it with the built-in magnets.
  3. Mount the Light: Peel the remaining protective film from the adhesive magnetic strips now attached to the light. Press the light firmly onto the cleaned installation surface (e.g., under a cabinet, inside a closet). Hold for a few seconds to ensure a secure bond.
  4. Optional Iron Surface Attachment: If installing on an iron surface (like a refrigerator), the light can be directly attached using its built-in magnets without the need for adhesive strips.

Operating Instructions

The BLS Under Cabinet Light offers multiple operating modes and customizable light settings.

Sensor Modes

Use the switch on the light fixture to select one of the four sensor modes:

  • Night Mode (Moon Icon): The light will activate only when motion is detected in dark conditions. Ideal for areas like kitchens or stairways at night.
  • Day Mode (Sun Icon): The light will activate when motion is detected, regardless of ambient light conditions. Perfect for dark closets or pantries.
  • Always On (ON): The light remains continuously on. Suitable for use as a flashlight or reading light.
  • OFF: The light is turned off.

The motion sensor has a detection range of 10 feet (3 meters) and a 120° angle.

Color Temperature and Dimming

The light offers three color temperature options and stepless dimming:

  • Color Temperature Selection: Press the control button to cycle through Warm Light (3000K), Natural Light (4500K), and Cool White Light (6000K).
  • Stepless Dimming: Press and hold the control button to adjust the brightness from 10% to 100%. Release the button when the desired brightness is reached.

Charging and Battery Life

The BLS Under Cabinet Light is equipped with a 2500mAh USB-C rechargeable battery.

  • Charging: Connect the included USB-C cable to the charging port on the light and to a standard USB power adapter (not included). The indicator light will show charging status.
  • Battery Life: A full charge can last up to 4 months in motion sensor mode (based on 10 activations per day, 20 seconds each). In Always On mode at 100% brightness, it provides approximately 8 hours of continuous light.
