Ex-Recessed, ceiling light fittings in metal design

eLLB 20…

(Zone 1, 2, 21, 22)

The Ex-recessed ceiling light fittings of the series eLLB 20  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. They are often used in the pharmaceutical and chemical industries, and experimental facilities, as well as in paint shops and spraying cabinets.

Designed for easy installation

The housing is made of white-painted steel sheet with an integrally moulded cover frame or, optionally, of polished stainless steel. It is installed securely in the ceiling by means of special fixing elements that allow a universal and simple mounting in recessed clean room ceilings that are 25 to 90 mm thick. In addition, it can also be fixed by means of two M8 drilled holes in the top of the housing. The hinged, frameless pane made of 6 mm thick safety glass is fixed with captive screws and has inside hinges. The sealing material is guaranteed silicone-leak-proof. Together with the generously dimensioned terminal compartment, the standard, twin-ended through-wiring allows a cost-saving installation.

Long-term safety

The luminaires of this robust lighting series with plastic enclosure are equipped with a highly-efficient electronic ballast that features a reliable EOL circuit. Thus, the lamps are checked for proper operation and shut down safely in the event of a malfunction at the end of the service life. In addition, the dual-channel structure of the electronic ballasts allows the safe operation of the second lamp if one lamp fails.

Versatile

The wide input voltage range and important national and international approvals allow the global use of this successful series of light fittings.

Special versions according to the NEC standards are available for use on the American market. CSA certification for the types of luminaires eLLB 202217 (2 x 17 W) and eLLB 204232 (2 x 32 W) allows their use there.
