PHILIPS LL550E MPM Gen2 WH Interact Sensor Unit for Low Installation Heights (4-12 m)

Managing lighting in large indoor spaces with high ceilings can be challenging—standard sensors often fail to provide reliable occupancy detection and daylight harvesting when mounted at low heights. The PHILIPS LL550E MPM Gen2 WH Interact Sensor Unit is specifically engineered for installation heights between 4 and 12 meters, delivering precise multi-point motion detection and continuous daylight regulation to maximize energy savings without compromising comfort.

Who is it for

This sensor is ideal for facility managers, electrical contractors, and building owners who need a dependable, DALI-2 compatible sensor for warehouses, production halls, gymnasiums, and retail spaces with low mounting heights. It integrates seamlessly with the Philips Interact Pro system, enabling smart lighting control and data-driven insights.
