How to Add a Photocell to an Outdoor Light

Adding a photocell to an outdoor light is a simple and efficient way to automate your lighting system, ensuring your lights turn on automatically at dusk and off at dawn. Photocells, also known as light sensors, utilize light levels to trigger the operation of your lights, eliminating the need for manual switching and enhancing energy efficiency. This guide will walk you through the process of installing a photocell to an outdoor light, providing clear instructions and essential tips to ensure a successful installation.

Choosing the Right Photocell

The first step is to choose the right photocell for your outdoor light. Photocells come in various models, each offering different features and functionalities. Consider the following factors when making your decision:

Type of Light:
The type of light you are working with will determine the appropriate photocell. For example, photocells for incandescent lights may differ slightly from those designed for LED lights.
Mounting Options:
Photocells are available with various mounting options, including wall-mount, post-mount, and surface-mount. Choose the mounting option that best suits your installation needs.
Voltage Rating:
Ensure the photocell's voltage rating matches the voltage of your outdoor light fixture.
Dusk-to-Dawn or Adjustable Settings:
Consider whether you need a basic dusk-to-dawn photocell or one with adjustable settings for customizing the on and off times.

Installing the Photocell

Once you have chosen the correct photocell, follow these steps to install it:

Turn off the power:
Before beginning any electrical work, it is crucial to turn off the power to the outdoor light fixture at the circuit breaker. Ensure the power is off by testing the light with a voltage tester.
Mount the photocell:
Choose a suitable location for the photocell, ensuring it is unobstructed and receives ample sunlight. Mount the photocell using the included mounting hardware.
Connect the photocell to the light fixture:
Connect the photocell wires to the corresponding wires in the light fixture's wiring compartment. The photocell usually has two wires: one black wire (hot) and one white wire (neutral). Connect the black wire to the black wire in the light fixture and the white wire to the white wire in the fixture.
Test the photocell:
Once the connections are made, turn the power back on at the circuit breaker. Observe the light fixture to ensure it turns on and off automatically when exposed to darkness and light, respectively.

Tips for Successful Installation

Here are some additional tips for successful installation of a photocell to an outdoor light:

Choose an appropriate location:
Mount the photocell in a location that is not obstructed by trees, buildings, or other objects that may cast shadows and interfere with its sensitivity to light levels.
Consider the orientation:
Point the photocell towards the sky, ensuring it receives unobstructed sunlight.
Adjust the sensitivity:
Some photocells offer sensitivity settings, allowing you to adjust the light level required to trigger the light on or off. Experiment with these settings to find the optimal balance for your needs.
Use weatherproof connections:
Ensure all wire connections are properly insulated and waterproof to withstand outdoor weather conditions.
Professional installation:
If you are unsure about any aspect of the installation process or are dealing with complex wiring, it is best to consult a qualified electrician for professional installation.

By following these instructions and tips, you can successfully add a photocell to your outdoor light, enhancing its functionality and reducing your energy consumption.
