Non-maintained operation means the LED only illuminates during mains power failure, providing emergency egress lighting for commercial, retail and public buildings. The 295mm diameter housing contains a single 5W LED module emitting 5500K daylight-white light through an open polycarbonate lens.\u003c\/p\u003e\n\u003cp\u003eDesigned for ceiling installation in corridors, stairwells, office spaces and retail areas where emergency lighting is required under UK Building Regulations, the Duceri fits a standard circular ceiling cut-out and connects to the mains supply via the included driver and battery pack. The battery charges continuously when mains power is present and provides emergency illumination for up to three hours during power failure. The IP20 rating limits use to dry indoor environments.\u003c\/p\u003e\n\u003cp\u003eThe white thermoplastic bezel sits flush with the ceiling surface once installed, with the open lens allowing direct downward light distribution during emergency mode. The lithium battery pack is housed within the driver enclosure behind the ceiling line, making servicing and battery replacement accessible without removing the entire fitting. At 0.42kg net weight the downlight mounts securely to standard plasterboard ceilings with the correct fixings.\u003c\/p\u003e\n\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.42\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.51\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e8.16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e295\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e75\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e310\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e340\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e320\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_D2413WH_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_D2411WH\u0026amp;D2413WHManual.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does non-maintained mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNon-maintained emergency lighting only illuminates during mains power failure.
