What are the benefits of installing a twilight switch?

Automates outdoor lighting at dusk/dawn. Eliminates manual operation, reduces energy 20–40%, improves security, ensures consistent lighting cycles.

How do I adjust the sensitivity of a twilight switch?

Photocell relay includes potentiometer (adjustment screw). Rotate clockwise increases sensitivity (lights ON at lower light levels). Test at twilight to calibrate.

Does a twilight switch malfunction in bad weather or cloudy conditions?

No, well-calibrated photocells function reliably in cloud cover. Brief cloud passages don't trigger switching (hysteresis delay prevents). Extreme fog may delay activation slightly.
