If you are interested in photocells for LED lighting, please contact us.Outdoor Lighting Fixtures, Not Just for Security Anymore. Our products are well constructed and feature long service lives. LiTian Lighting provides photocells that will fit in a variety of places, including outlet boxes, post lamps, or outdoor lights. Once everything is assembled, test your light as shown above. Always connect black wires to black wires and white wires to white wires.Ĭover all connections with electrical tape and tuck all the wires away.įinish installing your light fixture per the manufacturer's instructions. Cover the new connection with a wire nut and make sure it is tight. Twist together the black wire of the light fixture and the black wire of your house. To wire your new light fixture, use your pliers to cut about 3/8" of insulation away from the wires. ![]() Install the new light fixture with the pre-installed photoelectric switch using the mounting instructions that come with it. Turn off the power at the circuit breaker. To install a new light fixture, you may need the following: If you are installing a new light fixture then the procedure is similar to the one above. Cover the photocell with your hand-if the light turns on when the photocell is covered, your photocell is working properly.įinish installing the photocell by putting your light fixture back together. Make sure that the light switch is in the on position. To test the photocell, turn the power back on at the breaker. Make sure that there are no exposed copper wires. Tape your connections completely with electrical tape. Ensure that the cap is tight around the wires. Be sure to twist the exposed copper wire so that it forms a tight connection.Ĭonnect the second black wire on the photocell to the black wire on your light fixture, making sure that the copper wire is twisted together completely.Ĭover the new connections you made with electrical caps. Disconnect the black wire going from the house to the light fixture.Ĭonnect one black wire on the photocell to the black wire that comes from the building. Those black wires need to be tapped in to the black wire that runs between the light fixture and your structure’s main power. You should see two black wires on the photocell. You may want to document how it comes apart with photographs so that you can easily put it back together. Double check that the power is off by flipping the switch to the outdoor light to make sure it doesn’t turn on.ĭisassemble the housing that contains your exterior light. If you do not know which breaker powers your light, turn off all breakers in the building to ensure that power is cut off. Turn off the circuit breaker to your outside light. This project requires some electrical work, so if you do not feel confident or safe performing these tasks, you should contact an electrician to install the photocell for you. The following steps will guide you through the installation of a photocell sensor. How to Install a Photocell Sensor for Outdoor Use While a motion sensor might be useful to keep stray animals away from dumpsters and garbage cans, for example, a photocell can keep a parking lot safely and consistently lit for long periods of time. However, photocell sensors and motion sensors typically serve different purposes. Many outdoor lighting setupsuse motion sensors. As they sense the amount of light rather than operating at a set time, they don’t need to be adjusted when sunrise or sunset shifts with the seasons. Photocells work all year round, activating at dusk and turning off at dawn, even when the days are longer in summer or shorter in winter. The photocell acts similar to how a light switch would-as such, photocell sensors are also sometimes called photoelectric switches. With no user input required, there’s no concern about setting timers or forgetting to turn the lights on. This technology is convenient for all types of outdoor locations. As more light hits the plates, the resistance (the amount of current that travels through the resistor) changes, turning the light on and off. The photocell is made up of a resistor attached to photosensitive plates. Once the photocell detects low enough light levels, the light turns on or conversely, rising external light levels will turn the light off. ![]() Automatic lighting, such as streetlights, often uses photocell sensors-also known as photoeyes-to sense how much ambient light there is.
