When operated, luminaires generate heat. The following symbols are used for luminaires that can be mounted on flammable materials:

PROTECTION CLASSES WITH REGARD TO IGNITION/FIRE
Symbol Description
Symbol 1 Luminaires are suitable for direct mounting on normally flammable materials, in which you may not exceed 130° C (in normal operation) and 180° C (in fault case) for less than 15 min.
Symbol 2 Luminaires are suitable for direct mounting on materials that have normal or reduced flammability, in which you may not exceed 95°C (in normal operation), 130°C (in annormal operation) and 180°C (in fault case) for less than 15 min.. Maximum temperature on the mounting surface: 130 °C.
Symbol 3 Luminaires are suitable for direct mounting on materials for which the flammability properties are not known, in which you may not exceed 95°C (in normal operation) and 115°C (in abnormal operation fault case).
