Legrand Programmable 24-hour Astronomic Timer
April 20, 2026
Now available, the Programmable 24-hour Astronomic Timer, a simple solution for automatic control of a home’s exterior lighting. It’s designed with 24/7 programmable settings to turn lights on/off at a specific time of day and an astronomic feature to automatically adjust with local dusk to dawn times – even during daylight savings time.
