Q-Lúmen

Q-Lúmen is an intelligent public lighting solution based on IoT devices installed directly on luminaires and a web-based management platform. It enables individual control of each light point, with remote adjustments, scheduling, and continuous monitoring — without the need for physical intervention.

The platform centralizes real-time and historical data, providing a clear view of luminaire operation, performance, and location. This enables more efficient, sustainable, and cost-effective urban lighting management, reducing energy consumption and operational costs while improving public safety and overall well-being.

Count on QuatroIn to turn technical challenges into efficient and scalable solutions.
