IP
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.

Luminous efficacy (lm/W)
Efficacy: lm/W
The specific luminous flux reflects the relationship between luminous flux and power consumption. Just as with fluorescents, a distinction must be made between the light source’s specific luminous flux (LED component, measured at 25° or 85°C junction
temperature and with a standard control current) and that of a luminaire, including driver and optics.

U23
U23 is a recessed diffuser flatpanel.
The prismatic optics provides pleasant and even light for every application.
Also available in an IP44 (from below) version this luminaire can also be used in more demanding environments such as kitchens or sanitary rooms.
To complete the range a surface mounted version (R23) is available.
