Photocells
Photocells are sensors that detect light levels and help control outdoor lighting systems automatically. They're like light-sensitive switches that turn lights on when it gets dark and off when it gets bright. In landscaping, these devices are essential for managing landscape lighting, security lights, and other outdoor lighting features. They help save energy and ensure lights work only when needed. You might also hear them called "photo sensors," "photo eyes," or "dusk-to-dawn sensors." These are common in both residential and commercial landscaping projects.
