A lithium iron phosphate (LiFePO4) battery provides three hours of emergency backup at 170 lumens, operating in maintained, non-maintained or switched emergency modes depending on installation wiring. DALI dimming protocol is supported via the integrated driver, allowing luminaire output to be controlled from a compatible DALI system.\u003c\/p\u003e\n\u003cp\u003eDesigned for corridors, stairwells, commercial foyers, industrial loading bays and outdoor canopies requiring both routine illumination and emergency egress lighting, the bulkhead mounts to wall or ceiling surfaces using a hinged gear tray that pivots down for wiring access. The push-fit terminal block removes the need for screwdriver connections during installation. The 315mm diameter polycarbonate body with opal diffuser provides 115° beam angle coverage, and the IP65 rating allows use in wet or dusty environments including car park canopies and external loading areas.\u003c\/p\u003e\n\u003cp\u003eThe polycarbonate construction and opal diffuser distribute light evenly without visible LED hotspots, delivering between 1,230 and 1,410 lumens depending on the CCT setting selected (3000K produces 1,230lm, 4000K produces 1,410lm, 5700K produces 1,375lm). The luminaire projects 74mm from the mounting surface and the hinged gear tray allows lamp driver and battery access without removing the entire fitting from the wall or ceiling. Class II double-insulated construction means no earth connection is required. The LED array is rated for 50,000 hours L70B50 lifespan, with a 5-year warranty covering the luminaire (battery excluded from warranty).\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e315mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e74mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePolycarbonate\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\u003eIP65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003eII\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\u003eDiffuser\u003c\/td\u003e\n\u003ctd\u003eOpal\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\u003eSMD LED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Included\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eL70B50\u003c\/td\u003e\n\u003ctd\u003e50000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating (Class) post 2021 SLR\u003c\/td\u003e\n\u003ctd\u003eD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e115\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCCT\u003c\/td\u003e\n\u003ctd\u003e3000\/4000\/5700K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Colour\u003c\/td\u003e\n\u003ctd\u003eCCT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens\u003c\/td\u003e\n\u003ctd\u003e1230\/1410\/1375lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Light source only)\u003c\/td\u003e\n\u003ctd\u003e1800\/2000\/1920lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Em. mode)\u003c\/td\u003e\n\u003ctd\u003e170lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e14W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficacy (Light source)\u003c\/td\u003e\n\u003ctd\u003e147lm\/W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCRI\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;85\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e5 Year Guarantee\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty Information\u003c\/td\u003e\n\u003ctd\u003e(excluding battery)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/datasheet-BT14ACTDALIEM.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the colour temperature selected?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe CCT is set via a switch on the LED driver, accessible through the hinged gear tray.

The mode depends on how the electrician wires the luminaire during installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it be used outdoors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The IP65 rating protects against dust ingress and low-pressure water jets, making it suitable for external canopies, loading bays, car park soffits and other sheltered outdoor applications. It should not be used in locations where it will be submerged or subject to high-pressure hosing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does the emergency battery last?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe LiFePO4 battery provides three hours of emergency light at 170 lumens when mains power is lost. Battery lifespan depends on the number of discharge cycles and ambient temperature, but lithium iron phosphate chemistry typically offers longer service life than nickel-cadmium alternatives. The battery is excluded from the 5-year luminaire warranty.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":51391631229195,"sku":"BT14ACTDALIEM","price":70.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/1695006_135aa1ef-3c1c-4c34-a595-26e60b8f6b0e.jpg?v=1747062844","url":"https:\/\/niori.co.uk\/products\/14w-cct-adjustable-dimmable-led-emergency-bulkhead-white-ip65","provider":"Niori","version":"1.0","type":"link"}
