The tube outputs 2160 lumens and retrofits directly into standard T8 fluorescent fittings when the starter and ballast are bypassed for direct mains connection.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial, workshop and garage use where lighting needs change between tasks, the adjustable CCT function allows a single tube type to provide warm ambient light for rest areas, neutral cool white for general visibility, or bright daylight for detailed inspection work. The tube is non-dimmable and runs on 230V mains once the existing fluorescent ballast is removed and wiring is converted to direct LED operation.\u003c\/p\u003e\n\u003cp\u003eThe 1200mm length and standard G13 bi-pin base fit the majority of UK commercial and domestic T8 fluorescent fixtures manufactured from the 1980s onwards. The frosted polycarbonate outer diffuses the LED strip evenly along the length of the tube, avoiding the striped appearance of cheaper LED tubes. At 18W consumption for 2160lm output, the tube delivers 120lm\/W, comparable to other mid-range retrofit LED tubes in the E energy rating band.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e18W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e2160\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Shape\u003c\/td\u003e\n\u003ctd\u003eTube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eT8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating\u003c\/td\u003e\n\u003ctd\u003eE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKelvin\u003c\/td\u003e\n\u003ctd\u003eVariable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature\u003c\/td\u003e\n\u003ctd\u003eVariable\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\u003eLED or Halogen\u003c\/td\u003e\n\u003ctd\u003eLED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I change the colour temperature?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe CCT selector is on the base cap of the tube, accessible before installation. A small switch allows you to choose between 3000K, 4000K and 6500K. Once the tube is installed in the fitting, the colour temperature is fixed until the tube is removed and the switch is changed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this replace a fluorescent tube directly?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The tube requires the existing fluorescent ballast and starter to be removed and the fitting to be rewired for direct mains connection. This is a standard LED retrofit procedure but must be carried out by a qualified electrician. The tube will not work if simply inserted into an existing fluorescent fitting with the ballast still in circuit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it suitable for outdoor use?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe tube itself has no stated IP rating and is designed for indoor use in dry environments. It can be used in covered outdoor areas such as garages or carports if the fitting is weatherproof and the tube remains dry.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the lifespan?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEnergizer does not publish a specific lifespan for this tube in the supplied data. Most LED tubes in this category are rated between 25,000-30,000 hours, which equates to approximately 10-12 years of typical commercial use at 8 hours per day.\u003c\/p\u003e","brand":"Energizer","offers":[{"title":"Default Title","offer_id":46074628833547,"sku":"S28633","price":4.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S28632_3_4_1_561552ec-6c70-4df3-a78a-a162620aaa84.jpg?v=1730314637","url":"https:\/\/niori.co.uk\/products\/energizer-t8-18w-4ft-led-tube-cct-adjustable-3000k-4000k-6500k","provider":"Niori","version":"1.0","type":"link"}
