The unit operates in three modes: maintained (lamp on continuously with emergency backup), non-maintained (lamp off until mains failure), and switched (standard switched control with emergency backup), selectable during installation.\u003c\/p\u003e\n\u003cp\u003eDesigned for corridors, classrooms, utility rooms, storerooms, stairwells and back-of-house commercial spaces where emergency lighting compliance is required, the batten provides 3 hours of backup illumination on battery during mains power failure. The slim 63mm width and 82.5mm projection allow the fitting to sit close to the ceiling or wall without protruding into walkways or tight clearance zones. The IP20 rating suits dry interior environments only.\u003c\/p\u003e\n\u003cp\u003eThe pressed steel housing is powder-coated in white to blend with standard ceiling finishes, and the polycarbonate diffuser and end caps provide impact resistance in high-traffic areas. The high-frequency control gear reduces flicker and hum compared to older magnetic ballasts, making the fitting suitable for occupied spaces where noise and light quality matter. The Class I electrical construction requires earth connection during installation.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e1475mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e63mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e82.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePressed steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003eI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEmergency\u003c\/td\u003e\n\u003ctd\u003eMaintained \/ Non-maintained \/ Switched\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Technology\u003c\/td\u003e\n\u003ctd\u003eFluorescent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eT5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Included\u003c\/td\u003e\n\u003ctd\u003eNo\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\u003eMax.
