5.1. Surface Mount Installation

- Snap the puck light into the secured trim ring.
- Connect the wire lead to your 24-volt DC power supply and Armacost Lighting RGB+W LED controller, following their respective installation instructions.
5.2. Recess Mount Installation
- Identify the desired location for the puck light. Ensure there is sufficient clearance behind the mounting surface for the puck light body.
- Carefully remove the trim ring from the puck light by gently twisting or prying it off.
