The IP rating is a measure of the protection of a luminaire against the ingress of solid objects, dust and water. The IP rating is determined according to the IEC 60529 standard.

• IP20: Protected against large objects, such as a finger. This is the minimum value for luminaires.
• IP21: Resistant to drops perpendicular to the luminaire.
• IP22: Resistant to drops on a 15 ° tilted fixture.
• IP40: Protected against pointed objects larger than 1 mm, for example a screwdriver.
• IP41: Protected against pointed objects and drops that fall perpendicular to the luminaire.
• IP42: Protected against pointed objects and drops falling below 15 ° on the luminaire.
• IP44 from below: splash proof for water sprayed from below, when built into the ceiling.
• IP54: Protected against dust and water splashes from any direction.
• IP54 from below: splash-proof and dust-proof from below, when built into the ceiling.
• IP65: Spray-proof: the fixture can withstand a water jet from all angles.
• IP66: Water resistant: The luminaire can withstand a strong water jet from all angles.

When the mains power supply fails, the emergency lighting will come on for a certain period of time: the duration

• 60 minutes: suitable for many applications
• 180 minutes: Most common requirement for the UK. When the evacuation requires more time, for example in high-rise buildings or care centers
