      Luminaires suitable for mounting on normally combustible surfaces (ignition temperature at least 200°C) are marked with the ‘F’ symbol.

 

      Protected against 0.2 joules impact. Equivalent to impact of 0.25kg mass dropped from 80 mm above impact- IP65 ed surface. 

 

      Luminaires which can be applied indoors only if no specific pollution rates are expected. Offices, dry, heated industrial halls, shops, shopping malls and theatres are typical application segments. Protected against a solid object greater than 12.5 mm such as a finger.

 

      Protected against 20 joules impact. Equivalent to impact of 5kg mass dropped from 400 mm above impacted surface.

 

 

      Jet-proof Iuminaires which are applicable where the surroundings are hosed down frequently by water jets, or where luminaires are applied in a dusty environment. Although the luminaires are not fully watertight, the potential ingress of moisture will not have any harmful effect on the luminaire function. IP 65 luminaires are often available in impact-protected versions. Dust tight. No ingress of dust. Two to eight hours. Protected against jets of water. Limited ingress permitted.
