Four wattage settings (20W, 28W, 38W, 42W) and three colour temperatures (3000K warm white, 4000K neutral white, 5700K daylight) are switched via a selector on the driver housing, giving twelve possible output combinations from a single fitting.\u003c\/p\u003e\n\u003cp\u003eDesigned for offices, classrooms, retail and commercial interiors requiring glare-controlled linear lighting, the Viiva carries a UGR19 rating at the lowest wattage setting, reducing screen glare in workstation environments. The 48mm-wide profile mounts directly to ceilings via surface brackets or can be suspended on cables (sold separately). The 90-degree beam angle provides even light distribution across desks, worktops and corridors without harsh shadows or hotspots.\u003c\/p\u003e\n\u003cp\u003eThe extruded aluminium body measures 1500mm x 48mm x 63mm and weighs approximately 1.5kg, giving structural rigidity without sagging across the full span. The matt white finish pairs with white ceilings in modern commercial fit-outs and the IP20 rating suits dry indoor environments. Lumen output varies by wattage and CCT selection, ranging from 1705lm (20W, 3000K) to 3730lm (42W, 5700K) — see the Specification table for the full matrix.\u003c\/p\u003e\n\u003cp\u003eThe fitting is compatible with Knightsbridge's optional emergency kit (sold separately), which converts the Viiva into a maintained or non-maintained emergency luminaire for compliance with BS 5266 in commercial premises requiring escape route lighting. The Class I fitting requires earthing on installation and operates on 230V 50Hz mains.\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\u003e1500mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e63mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e48mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eAluminium\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\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e20\/28\/38\/42W\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\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e90\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e90°\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\u003e1705\/1840\/1860\/2185\/2385\/2390\/3130\/3420\/3355\/3345\/3730\/3665lm\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-VVA5W.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I change the wattage and colour temperature?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe driver housing has a selector switch accessible during installation.
