The pressed steel body houses a hinged gear tray with push-fit terminals, an opal polycarbonate diffuser, and rear and end conduit entry points spaced to BESA standards. The modular design allows optional microwave sensing and emergency kit integration using Knightsbridge MODMWS and MODEMKIT accessories (sold separately).\u003c\/p\u003e\n\u003cp\u003eDesigned for corridors, changing rooms, storage areas, back-of-house access routes and secondary circulation spaces where moderate lumen output is needed without the footprint of higher-wattage battens. The 1225mm length suits standard 4ft spacing on commercial ceilings, and the 61mm width keeps the fitting discreet on surface-mount installations. The 120-degree beam angle provides broad distribution suitable for general illumination rather than task lighting.\u003c\/p\u003e\n\u003cp\u003eThe IP20 rating limits use to dry indoor locations. The white powder-coated finish blends with most commercial ceiling and wall surfaces. The hinged gear tray allows access to the driver and terminals for maintenance without removing the entire fitting from the ceiling, and the push-fit terminals accept solid or stranded cable without the need for ferrules. The constant-current driver operates on 230V 50Hz mains and is non-dimmable.\u003c\/p\u003e\n\u003cp\u003eThe integrated LED is rated for 100,000 hours L70B50 lifespan, meaning that after 100,000 hours of operation at least 70% of the LEDs will still be producing at least 70% of their original lumen output. The 136lm\/W efficacy at the light source level gives an energy rating of Class D under the 2021 Supplier Labelling Regulation. The fitting carries a 5-year manufacturer warranty.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\" style=\"width: 100.036%; height: 470.4px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 52.6848%;
