Ex-Recessed-mounted, ceiling light fittings in compact metal design

RLF/RLF-INOX 250 18 – 58 W / RLF/RLF-INOX 250… N 18 – 36 W

(Zone 1, 2, 21, 22)

The Ex recessed-mounted, ceiling light fittings RLF .. are equipped with EVG 09 electronic ballasts and are suitable for two-pin fluorescent lamps. These lamps are used for surface and flush mounting in ceilings, in particular in clean rooms where smooth, flush surfaces are very important. The area of application is in the pharmaceutical and chemical industries, and experimental facilities, as well as in paint shops and spraying cabinets.

Designed for easy installation

The housing comprises white-painted steel sheet with an optional cover frame for ceiling mounting. The type RLF-INOX is made of polished stainless steel. In addition, it can also be fixed by means of two M8 drilled holes on the top of the housing. The hinged, frameless pane made of 5 mm thick safety glass is fixed with 3 resp. 4 captive screws and has inside hinges. The EPDM sealing ensures the high degree of protection IP65.

Long-term safety

Thanks to its large input voltage range, the latest generation of electronic ballasts can be used internationally and features an EOL circuit. The dual-channel structure of the electronic ballasts allows the safe operation of the second lamp if one lamp fails.


In conjunction with the generously dimensioned terminal compartment, the standard, twin-ended through-wiring allows a cost-effective installation. The luminaire switch reliably prevents the light from being turned on while the cover is open.

If you need a reliable and decentralized emergency lighting

The self-contained emergency light fitting RLF … N ensure decentralized emergency lighting, independent of central systems. These luminaires in particular offer significant cost advantages, particularly in large-scale installations.
