CorroLUME® NL Weatherproof Zone 1 Flourescent Twin Lamp from Hella Lighting.

CorroLUME® NL luminaires are highly specialised lights for use in Zone 1 hazardous areas, and offer a high resistance to corrosion and attack from a wide spectrum of aggressive elements commonly found in mining, industrial and chemical plants.
Each CorroLUME® NL luminaire comprises a single-piece moulded body in self-extinguishing glass-fibre-reinforced polyester material, with a scrim added to improve strength. Flame retardancy is to UL 94V0. Captive external body inserts with blind M8 thread enable various mounting options. Internally the inserts carry the control gear rail, and the reflector mounting support columns. The diffuser lens is formed in clear, UV stabilised, impact resistant self extinguishing polycarbonate. CorroLUME® lenses are designed with a smooth outer surface for easy cleaning with pressurised air or water. The lens is fastened againstthe body using a heavy welded stainless steel frame, with special captive, stainless steel socket head machine screws. The lens and frame hinges to one side when opened for safe and easy service access.

A specially designed Ex d rated electronic ballast is mounted on a robust electroplated control gear rail, fitted with an Ex e rated terminal block and special G13 single lead bi-pin lamp holders. The rail also incorporates an isolating switch, a safety factor in the event of accidental opening of the luminaire whilst still connected to the power circuit. A white epoxy powder coated steel cover, mounted on the gear rail by two captive thumbnuts, acts as a reflector. HELLA CorroLUME® lights use a custom formulated neoprene gasket, bonded directly into the body to ensure a very long service life and high reliability.

The luminaire is provided with entries at each end, one of which is fitted with an Ex e rated compression gland suitable for 6 to 12mm diameter flexible cable and the other sealed off with a stopper.

The CorroLUME® NL is equipped with specially designed and approved components and fully encapsulated custom designed electronic control gear, in full compliance with the appropriate national hazardous area classification standards.

CorroLUME® NL lights must be installed and used in accordance with the national requirements imposed on equipment of this type of luminaire.

Optional eyebolts, pole clamps, brackets, and anti-vibration mountings are available. CorroLUME® NL lights comply with IEC 60598-2-1, IEC 60079-0, IEC
