How it works in real life

LIGHT KEEPER is an urban lighting cabinet controller installed inside street lighting cabinets: the weatherproof enclosures that house the electrical components controlling groups of streetlights across a zone or district. Positioned at the heart of the local network, it continuously monitors the entire cabinet's electrical status, tracking current, voltage, power, and energy consumption in real time. Once connected to the HORIZON management platform, LIGHT KEEPER becomes the command center for its entire lighting zone. It can execute dimming schedules, detect electrical faults instantly, and operate autonomously even during cloud outages. By consolidating control over multiple luminaires into a single point, it provides city operators with a reliable, scalable foundation for efficient and sustainable urban lighting management.
