The integrated SMD LED array delivers 3600 lumens at 4000K cool white through an opal polycarbonate diffuser, with a 3-hour emergency battery backup that maintains 165 lumens when mains power fails. The fitting operates in maintained, non-maintained, or switched emergency modes.\u003c\/p\u003e\n\u003cp\u003eDesigned as a direct replacement for older fluorescent tube battens in offices, schools, healthcare facilities and retail environments, the SUR5SLEM provides uniform ceiling illumination with a 115-degree beam angle and minimal glare. The pressed steel housing and opal diffuser combine to give an even light distribution across workspaces, corridors and open-plan areas. Push-fit terminals with loop-in\/loop-out wiring reduce installation time when fitting multiple units in series.\u003c\/p\u003e\n\u003cp\u003eThe 45mm projection keeps the fitting low-profile against ceilings, while the white powder-coated steel housing blends into standard commercial ceiling finishes. The fitting is rated IP20 for dry interior use and carries Class I earthing. At 140.3lm\/W efficacy the SUR5SLEM meets current Eco Design and ErP requirements, and the L70B50 rating of 50,000 hours indicates the LED will maintain 70% of its initial output for approximately 5.7 years of continuous operation. A suspension kit for pendant mounting is available separately. The fitting is compatible with Knightsbridge motion and daylight sensors for additional energy saving.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e1500 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e145 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e45 mm\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\u003eConstruction 2\u003c\/td\u003e\n\u003ctd\u003e\u0026amp; polycarbonate\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\u003eI\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\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\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eNo\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\u003e4000 K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Colour\u003c\/td\u003e\n\u003ctd\u003eCool White\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens\u003c\/td\u003e\n\u003ctd\u003e3600 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Light Source only)\u003c\/td\u003e\n\u003ctd\u003e5600 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Em. mode)\u003c\/td\u003e\n\u003ctd\u003e165 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e40\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficacy\u003c\/td\u003e\n\u003ctd\u003e140.3 lm\/W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCRI\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDriver Type\u003c\/td\u003e\n\u003ctd\u003eConstant Current\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e5\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\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_4475257_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_1048668.pdf\" target=\"_self\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the emergency duration?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe integrated battery provides 3 hours of emergency lighting at 165 lumens when mains power fails.
