The polycarbonate housing and diffuser carry an IP65 rating against water ingress and an IK10 impact rating, meeting the standards for car parks, loading bays, external staircases and corridors where fixtures face weather exposure and physical contact.\u003c\/p\u003e\n\u003cp\u003eThe integrated emergency function provides up to 3 hours of illumination during mains failure, powered by a lithium iron phosphate (LiFePO4) battery known for longer cycle life and lower self-discharge than older nickel-cadmium alternatives. Wattage is adjustable at installation between 14W, 16W and 18W, and colour temperature can be switched between 3000K, 4000K and 5700K to match the intended environment without needing multiple SKUs. At 18W on 4000K the fitting delivers 1800 lumens across a 130-degree beam, covering typical 3-4m ceiling-to-floor heights in corridors and staircases.\u003c\/p\u003e\n\u003cp\u003eThe bulkhead supports DALI dimming for integration with building management systems and also offers push-dim functionality where DALI is not available. Installation uses push-fit terminals, a hinged gear tray for access to the driver and emergency module, and a twist-lock diffuser that removes without tools. Multiple conduit entry points on the base plate allow cable entry from different angles depending on wall or ceiling mounting. The polycarbonate is UV-stabilised to resist yellowing under sunlight. The standard finish is white; optional bezels in matt black, chrome and eyelid designs are available separately.\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\u003e300mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e65°\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\u003eClass\u003c\/td\u003e\n\u003ctd\u003eII\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\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e14\/16\/18W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e130\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e130°\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\u003e1300\/1400\/1400,1500\/1600\/1500,1600\/1800\/1700lm\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-BTEVDALIEM.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does the emergency battery last during power failure?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe integrated LiFePO4 battery provides up to 3 hours of emergency illumination when mains power is lost.
