Setup and Installation

The Lightbiz 78 LED Closet Light offers two convenient installation methods:

Method 1: Magnetic Adhesion (for ironwork surfaces)

  1. Ensure the ironwork surface is clean and dry.
  2. The light has built-in strong magnets. Simply place the light directly onto any ironwork surface.

Method 2: Adhesive Magnetic Strip (for non-ironwork surfaces)

  1. Clean the desired installation surface thoroughly to ensure it is free of dust and grease.
  2. Peel off the protective film from one side of the provided adhesive magnetic strip.
  3. Firmly press the adhesive side of the strip onto the clean surface. Hold for a few seconds to ensure strong adhesion.
  4. Once the magnetic strip is securely attached, the LED light can be magnetically attached to the strip. This allows for easy removal for charging.

Important Note:

  • Avoid placing two lights too close to each other in auto-mode, as they may interfere with each other's motion detection.
  • For optimal adhesion, ensure the surface is smooth and non-porous.
