The CCT adjustment allows switching between three colour temperatures—3000K warm white, 4000K neutral white, and 5700K daylight—via a selector on the driver, making it adaptable to different work environments without changing the fitting.\u003c\/p\u003e\n\u003cp\u003eDesigned as a direct replacement for conventional 4ft fluorescent battens in offices, warehouses, workshops and utility spaces, the fitting includes rear and end conduit fixing points that align with existing fluorescent mounting positions. The DALI control gear integrates into simple room or networked building management systems, allowing centralised dimming and scene control across multiple fittings. A hinged gear tray and push-fit loop-in-loop-out terminals reduce installation time by allowing daisy-chained wiring without junction boxes.\u003c\/p\u003e\n\u003cp\u003eThe opal polycarbonate diffuser spreads the LED array into an even 105° beam with a CRI of \u0026gt;85, minimising harsh shadows and glare in task lighting applications. At 4000K the fitting outputs 4480lm from the 32W LED, giving an efficacy of 140lm\/W. The L70B50 rating of 60,000 hours predicts the LED will retain 70% of initial output after approximately seven years of continuous use, reducing maintenance frequency compared to fluorescent tubes.\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\u003e1225 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e61 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e71 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\u003eLamp Technology\u003c\/td\u003e\n\u003ctd\u003eLED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eL70B50\u003c\/td\u003e\n\u003ctd\u003e60000\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\u003e105\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCCT\u003c\/td\u003e\n\u003ctd\u003e3000\/4000\/5700 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\u003e3790\/4480\/4120 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Light Source only)\u003c\/td\u003e\n\u003ctd\u003e4970 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficacy\u003c\/td\u003e\n\u003ctd\u003e157.16 lm\/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\u003eDriver Type\u003c\/td\u003e\n\u003ctd\u003eDALI\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_5077517_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_1126626.pdf\" target=\"_self\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the CCT adjusted?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA selector switch on the DALI driver allows you to choose between 3000K warm white, 4000K neutral white, and 5700K daylight.
