E2 luminaires are suitable for gas and dust ATEX zones, with markings:
EX II 2D Ex tb IIIC T80 Db, and EX II 3G Ex ec nA IIC T4 Gc.
They are built for extreme environments. The luminaire is IP66 and IP69K, which makes it suitable for cleaning with high pressure, as is often the case in the food industry. In chlorine environments E2 can be supplied with electropolished and painted brackets that offer double protection against corrosion.
Every device is tested under a vacuum for water resistance before it leaves the factory.
