Photocell FAQ Section
What is the typical lifespan of a photocell?
Our high-quality photocells are designed for long-term operation with an average lifespan of 100,000 switching cycles or approximately 10 years of continuous use. The actual lifespan may vary depending on environmental conditions and electrical load characteristics. For optimal performance, we recommend periodic cleaning of the sensor lens to maintain light sensitivity.
How do I adjust the sensitivity of my photocell?
Most of our photocell models feature an adjustable sensitivity control, typically a small rotary dial or screw located on the device. To adjust: 1) Locate the sensitivity control, 2) Turn clockwise to increase sensitivity (lights turn on earlier at dusk), 3) Turn counterclockwise to decrease sensitivity (lights turn on later). We recommend making small adjustments and allowing a full day-night cycle to observe the effects before further adjustment.
Photocell Installation Guidelines
For optimal performance, photocells should be installed according to these best practices:
- Mount the sensor where it can receive unobstructed daylight
- Avoid locations near other artificial light sources
- Position the sensor facing north in northern hemisphere installations
- Maintain a clearance of at least 3 feet from surrounding objects
- Ensure wiring complies with local electrical codes
More Photocell Questions Answered
Can photocells work through glass or plastic enclosures?
Photocells are generally designed to operate without obstructions between the sensor and ambient light. While some models may function through clear materials, most will experience reduced performance when installed behind glass or plastic. The enclosure material can filter specific light wavelengths and create temperature variations that affect sensor accuracy. For reliable operation, we recommend direct exposure mounting whenever possible.
