The fitting includes a built-in emergency battery system that provides automatic backup lighting during mains power failure, making it suitable for corridors, stairwells, warehouses and industrial areas requiring both primary illumination and emergency exit lighting compliance.\u003c\/p\u003e\n\u003cp\u003eDesigned for surface mounting on ceilings or walls, the batten measures approximately 1200mm in length and projects 100mm from the mounting surface when fitted. The IP65 weatherproof rating protects against dust ingress and water jets from any direction, allowing installation in damp or outdoor covered locations including loading bays, car parks, storage facilities and external walkways. The 120-degree beam angle provides wide flood coverage suitable for corridors 2-3m wide or open plan areas when multiple fittings are spaced at 3-4m intervals.\u003c\/p\u003e\n\u003cp\u003eThe emergency function automatically activates when mains power is interrupted, drawing from an internal rechargeable battery to maintain illumination for the duration specified in the installation manual. When mains power is restored the battery recharges automatically. The non-corrosive finish (NCF) coating on the housing resists rust and corrosion in humid or coastal environments, extending the fitting's working life in challenging industrial conditions. Stainless steel mounting clips resist corrosion better than zinc-plated or plastic alternatives.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e42W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e4,800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating\u003c\/td\u003e\n\u003ctd\u003eE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKelvin\u003c\/td\u003e\n\u003ctd\u003e4,000K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature\u003c\/td\u003e\n\u003ctd\u003eCool White\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLED or Halogen\u003c\/td\u003e\n\u003ctd\u003eLED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eZone\u003c\/td\u003e\n\u003ctd\u003eSuitable for use in Zones 3, 2 and 1 only (not Zone 0)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does the emergency backup last?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe duration of emergency backup lighting depends on the battery capacity fitted.
