The integrated SMD LED delivers between 950-1575 lumens depending on the chosen wattage and CCT combination, providing output flexibility across commercial retail, office and hospitality installations where lighting needs may change between zones or over time.\u003c\/p\u003e\n\u003cp\u003eDesigned for ceiling voids of 100mm minimum depth, the downlight requires a 125mm diameter cut-out and sits 69.5mm above the ceiling plane once recessed. The die-cast aluminium housing carries an IP40 rating (IP20 from above), making it suitable for general interior use in dry environments. The opal polycarbonate diffuser provides glare-controlled, even light distribution across a 100-degree beam angle. Plug-and-play connectors speed up installation, and the fitting is compatible with Knightsbridge's EMKIT2 emergency conversion kit for maintained or non-maintained emergency operation.\u003c\/p\u003e\n\u003cp\u003eThe white powder-coated finish blends into most ceiling planes without drawing attention to the fitting itself. 0-10V dimming compatibility allows integration with commercial lighting control systems, though specific dimmer compatibility should be verified before pairing. The driver carries Class II double-insulated construction, removing the need for an earth connection. L70B50 rated to 50,000 hours, the LED is expected to retain 70% of initial output after approximately 17 years of continuous use at 8 hours per day.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e143 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e69.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Void\u003c\/td\u003e\n\u003ctd\u003e100 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCut-out Diameter\u003c\/td\u003e\n\u003ctd\u003e125 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eAluminium\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\u003eII\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP40 (IP20 from above)\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\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\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\u003eC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCCT\u003c\/td\u003e\n\u003ctd\u003e3000\/4000\/5000 K\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\u003e950\/995\/1000\/1290\/1360\/1350\/1490\/1575\/1575 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Light Source only)\u003c\/td\u003e\n\u003ctd\u003e1810 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e41189\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficacy\u003c\/td\u003e\n\u003ctd\u003e152.57 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\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e5\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_6284480_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_1820982.pdf\" target=\"_self\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I change the wattage and colour temperature?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBoth settings are adjusted via switches on the driver unit before installation.
