Vandal-proof luminaire with LED modules, adapted for ceiling mounting inside rooms intended for potentially aggressive people or in corridors. It is characterized by a very high degree of impact resistance (IK11+). The housing is made of galvanized steel, painted with modified powder paint. The lampshade is made of thick polycarbonate, which ensures its durability, and a special lock prevents unauthorized persons from accessing the interior of the luminaire. The design solutions used minimize the risk of self-harm or suicide attempts using it. Optional versions are available: with adaptation for cooperation with the ZB central battery, with a power supply equipped with a DALI DA interface or with an SNS motion sensor.
