The batten delivers up to 4,500lm output at 4000K on the 31W setting, with efficacy reaching up to 173lm\/W at the light source. The pressed steel housing and opal polycarbonate diffuser provide a clean white finish suitable for commercial, retail back-of-house, storage rooms and corridor applications.\u003c\/p\u003e\n\u003cp\u003eDesigned for quick installation in both new builds and retrofit scenarios, the batten includes rear and end conduit entry points and a hinged gear tray that opens without removing the fitting from the ceiling, allowing access to the terminal block and wattage\/CCT switches. The fitting mounts to standard 600mm centres or BESA boxes. The modular design accepts plug-in microwave sensors (MODMWS) and emergency backup modules (MODEMKIT), both sold separately, without rewiring the fitting.\u003c\/p\u003e\n\u003cp\u003eThe selectable wattage function allows one SKU to cover multiple brightness requirements: 17W provides 2,500-2,600lm depending on CCT, 22W provides 3,100-3,300lm, 26W provides 3,600-3,900lm, and 31W delivers 4,100-4,500lm. The CCT switch sits behind the diffuser and is set during installation, allowing the installer to match ambient light temperature to the surrounding space without stocking three different fittings. The 120° beam angle provides wide, even distribution across open-plan areas and corridors.\u003c\/p\u003e\n\u003cp\u003eThe batten carries an IP20 rating for dry indoor use, Class I earthed protection, and a 7-year manufacturer warranty. The LED module is rated to 100,000 hours at L70B50, meaning at least 70% of the initial lumen output is maintained for 100,000 hours. The constant-current driver operates on 230V 50Hz mains with no dimming capability. CRI exceeds 85 across all colour temperature settings.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e1225mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e61mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e70mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePressed steel \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\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\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\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\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\u003e100000\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\u003e120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCCT\u003c\/td\u003e\n\u003ctd\u003e3000\/4000\/5700K\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\u003e2500\/2600\/2600,3100\/3300\/3200,3600\/3900\/3700,4100\/4500\/4300lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Light source only)\u003c\/td\u003e\n\u003ctd\u003e2700\/3000\/2800,3500\/3900\/3600,4100\/4400\/4200,4700\/5200\/4800lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e17\/22\/26\/31W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficacy (Light source)\u003c\/td\u003e\n\u003ctd\u003e173\/172\/169\/163lm\/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\u003eConstant Current\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e7 Year Guarantee\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\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\/datasheet-BATMCW4.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the wattage and colour temperature adjusted?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBoth settings are controlled by DIP switches accessible when the hinged gear tray is opened.
