For example, if the lighting system is being used to illuminate a parking lot, the photocell should be located near the edge of the lot, facing away from the lights. This will ensure that the photocell is not affected by the light from the fixtures and that the lights are turned on when necessary.
For most applications, a height of between 6-8 feet is recommended . Additionally, the photocell should be angled in such a way that it is facing the area that will be illuminated by the lights. This will ensure that the photocell accurately detects changes in light levels and turns the lights on or off as required.
They are used in many applications for on-off control especially in lighting installations. In lighting applications, Photocells are placed in streetlights to control when the lights are ON or OFF. During daylight, light falling on the photocell causes the streetlights to turn off and during night hours or darkness to turn on.
A photocell is an electronic device that senses the amount of light in its surrounding environment. It is used to automatically turn on or off lights, depending on the amount of natural light present. The primary purpose of a photocell is to save energy by reducing the use of artificial lighting when natural light is sufficient.
Ceiling-mounted: Ceiling-mounted photocells are typically installed in indoor areas, such as offices, classrooms, and warehouses. They are commonly used to control the lighting in these areas and can help save energy by turning off lights when the room is not in use.
A photocell switch is essentially a light dependent resistor, LDR. Its resistance decreases with increasing incident light intensity. They are used in many applications for on-off control especially in lighting installations. In lighting applications, Photocells are placed in streetlights to control when the lights are ON or OFF.

Photocells must be hardwired to a compatible Leviton lighting control system. The photocell measures ambient light in a specific area and sends this data to a dimmer or relay that, in turn, adjusts fixtures to a constant lighting level as measured in that specific area. Daylight
photocell can be small in size, where voltages and/or currents are higher, the photocell must be physically larger so that the semiconductor film can dissipate the heat. The following curve of power dissipation versus ambient temperature describes the entire series of cells for operation in free air at room ambient (25°C).
A photocell, also known as a photoresistor or light-dependent resistor (LDR), is an electrical component that changes its resistance based on the amount of light it is exposed

Hence the PECU must be capable of operating the load over the range of likely load conditions, including common failure modes of lantern control gear. Ratings It is important to ensure that the maximum ratings are not exceeded, care must be taken to observe both the current rating and also the maximum capacitive load that can be connected.
The mounting angle of the photocell is also important to consider. The photocell should be mounted between 6-8 feet of the window area, central to the area illuminated by the electrical lighting that will be controlled. In all cases, the photocell must be mounted so that it looks at reflected light only and not at any direct light.

Our photocell PR1a is a masterpiece of precision and performance with smallest possible dimensions. The transmitter of the photocell sends a modulated infrared beam. The receiver checks the infrared beam and triggers an impulse for each interruption. All photocells can be universally used with a reflector or as sender and receiver photocell.
