- Insert MR16 Bulb: Carefully insert your MR16 LED bulb into the GU5.3/Bi-pin socket.
- Install the Base: Place the assembled base and bulb into the prepared ceiling opening. Secure the base using the integrated clips or springs (if present, typical for recessed fixtures) or by fastening it to the recessed housing. The base is adjustable, allowing you to direct the light as needed after installation.
- Restore Power: Once the base is securely installed and all connections are verified, restore power at the circuit breaker.
Important: If you are unsure about any step of the installation process, consult a qualified electrician.
5. Operating Instructions
Once installed and powered, the PHILCO 51811 recessed base operates in conjunction with the MR16 LED bulb. The light can be turned on or off via the wall switch connected to the circuit. The inner ring of the base allows for directional adjustment of the light beam.
- Adjusting Light Direction: Gently pivot the inner ring of the base to direct the MR16 bulb to your desired angle. Do not apply excessive force.
- Bulb Replacement: Ensure power is off before attempting to replace the MR16 bulb. Allow the bulb to cool completely before handling.
