4. Setup and Installation
The Barrina Black Light Bar offers multiple installation options for versatility.
4.1 Mounting Options
Choose the most suitable mounting method for your application:
- Magnetic Mounting: The light bars have small magnets on both ends. They can be directly attached to any ferrous metal surface. For non-magnetic surfaces, use the provided adhesive iron sheets. Peel the backing from the adhesive iron sheet and stick it to your desired surface, then attach the light bar magnetically.
- Clip Mounting: Use the provided mounting clips and screws to secure the light bar to a wall or ceiling. Mark the desired positions, drill pilot holes if necessary, insert wall anchors (if applicable), and screw the clips into place. Snap the light bar into the clips.
- Zip Tie Mounting: For temporary installations or attachment to pipes/bars, use the provided zip ties through the designated holes on the mounting clips.
