A major advantage of using a photocell in outdoor lighting is its ability to automate lighting control based on ambient light levels. Photocells, also known as light sensors, detect the amount of natural light available. When darkness falls, the photocell activates the outdoor lighting system, ensuring that lights turn on automatically at sunset without the need for manual operation. This not only provides convenience but also enhances energy efficiency by ensuring that lights are only used when needed. The automation streamlines outdoor lighting management, making it ideal for applications such as security, safety, and aesthetics in public spaces and residential areas.

While the other options offer potential benefits, they do not accurately capture the primary function and significant advantage provided by a photocell in outdoor lighting scenarios.
