The fitting houses the LED driver and emergency battery pack within a pressed steel body finished in white, with an opal polycarbonate diffuser running the full length of the batten to distribute light evenly across the 120° beam angle.\u003c\/p\u003e\n\u003cp\u003eDesigned as a direct replacement for traditional T8 fluorescent batten fittings in commercial, educational and industrial spaces, the batten provides maintained, non-maintained or switched emergency operation selectable via internal controls. In mains power mode the fitting delivers 3000lm at 4000K cool white. During a power failure the emergency mode activates automatically, providing 290lm for three hours to maintain safe exit lighting in corridors, stairwells, warehouses and back-of-house areas.\u003c\/p\u003e\n\u003cp\u003eThe pressed steel construction and IP20 rating suit dry indoor environments. The batten measures 1525mm long × 60mm wide × 85mm deep and mounts directly to ceilings or suspended grid systems via the end brackets. The constant-current driver provides stable output without requiring external control gear. At 113lm\/W efficacy and a 50,000-hour L70B50 lifespan, the fitting reduces both energy consumption and maintenance frequency compared to fluorescent equivalents.\u003c\/p\u003e\n\u003cp\u003eThe 5-year warranty covers the fitting and LED components but excludes the emergency battery pack, which typically requires replacement after 3-4 years of operation depending on discharge frequency. The fitting is rated Class I and requires an earthed supply connection. The opal diffuser softens glare while maintaining good light transmission for task visibility in work areas.\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\u003e1525 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e60 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e85 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\u003eLED\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\u003e120\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\u003e3000 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Light Source only)\u003c\/td\u003e\n\u003ctd\u003e3325 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Em. mode)\u003c\/td\u003e\n\u003ctd\u003e290 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e26\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficacy\u003c\/td\u003e\n\u003ctd\u003e113 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_3511302_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_813966.pdf\" target=\"_self\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between maintained, non-maintained and switched emergency modes?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMaintained mode keeps the emergency lamp lit continuously alongside mains power. Non-maintained mode only lights the emergency lamp during power failure. Switched mode allows the fitting to be controlled by a wall switch during normal operation but still provides emergency backup when mains power fails. The mode is selectable via internal controls during installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does the emergency battery last?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe emergency function provides 290lm output for three hours during a power failure. The battery pack itself typically lasts 3-4 years depending on discharge frequency and requires replacement to maintain emergency function. Battery replacement is not covered under the 5-year fitting warranty.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it replace a traditional T8 fluorescent batten?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The 1525mm length and mounting bracket configuration match standard 5ft T8 batten fittings. The integrated LED eliminates the need for separate tubes and control gear, and the 3000lm output at 26W matches or exceeds the performance of a twin 58W fluorescent installation while using less than half the power.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat ceiling height and spacing is recommended?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 120° beam angle and 3000lm output suit ceiling heights of 2.5-4m in commercial and industrial spaces. For general lighting in corridors and warehouses, spacing battens 3-4m apart typically provides adequate coverage. For task lighting at workstations, closer spacing or supplementary fittings may be needed.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":45293986677003,"sku":"T8BLED15EM1","price":63.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/211208_64d9e392-02f3-404a-b10d-fc6088b58681.jpg?v=1714667135","url":"https:\/\/niori.co.uk\/products\/single-5ft-26w-led-emergency-batten-4000k-white","provider":"Niori","version":"1.0","type":"link"}
