LFN -P series fluorescent light fittings are normally used in the chemical and petrochemical plants, off-shore platforms, refineries and any other industry where hazardous atmospheres (gas and combustible dust) are potentially present. The LFN -P range of Zone 2 Lighting has been designed to meet the main requirements of illumination of working areas.
The light fitting is equipped with an interlock device. This can be mechanically connected with the internal Ex d safety switches, that automatically cut-off the power when the enclosure is opened.

The LFN -P series fluorescent lighting fixture are available with two different bodies suitable for installation of single or double fluorescent tube to satisfy every illumination requirements inside hazardous areas classified as Zone 2 and /or Zone 22. The internal wiring is designed to allow any combination of loop-in loop-out installation. The light fitting can be installed using different mounting types as described in dedicated section of this catalogue.
The materials used to manufacture the LFN-P series have been studied to grant the maximum protection against the highly corrosive agents present in these industries:
• the body in glass fiber reinforced polyester (GRP), provides a very high mechanical strength together with a good resistance against the UV ray effects;
• the transparent diffuser in UV ray resistance polycarbonate has a self-extinguishing property according to Standard UL 94;
• the gasket on cover grants an IP66 protection level ;
• the closing system in one single spot, apart from facilitating greatly the maintenance operations, is itself a guarantee of first-rate holding system since it provides a constant pressure of seals over all the perimeter of the diffuser ;
• the internal electrical components are fully sealed to prevent any corrosive action that could cause electrical faults;
• the body has two cable entries M25x1.5 on one side and one cable entry M25x1.5 on the opposite side so to allow any loop-in loop-out installation. On request it’s possible to have two cable entries M25x1.5 on both sides;
• all the light fittings are equipped, as standard, with one cable gland and two stopping plugs in polyamide, Atex certified. Other materials or combinations are available as option;
• two kinds of lampholder: G13 for traditional T8 fluorescent tubes and G5 for new generation of T5 fluorescent tubes;
• electronic ballast, equipped with some self-protective functions, works with a multirange voltage and has a two-supply circuit design so to continue to energize one fluorescent tube in case the second one is faulty;
