Both wattage and CCT are adjusted via switches on the fitting before installation, allowing one product to serve multiple lighting requirements across different rooms and applications. The integrated LED delivers between 1370lm and 3155lm depending on the wattage and CCT combination selected.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial and office installation, the Viiva suits open-plan offices, meeting rooms, retail displays, corridors and reception areas where consistent linear light is needed without ceiling recesses. The fitting can be surface-mounted directly onto ceilings or suspended on cables, and the 1200mm length pairs well with 1200mm ceiling grid systems common in UK commercial interiors. The UGR19 rating at low output reduces glare on computer screens and workspaces, making it suitable for desk-height visual tasks.\u003c\/p\u003e\n\u003cp\u003eThe matt black aluminium body provides both thermal management for the LED driver and a contemporary architectural finish that pairs with black metalwork and exposed services ceilings. The 63mm height and 48mm width give a slim profile that sits close to the ceiling when surface-mounted. The IP20 rating limits use to dry indoor spaces, and the Class I earthed construction requires connection to mains earth. The fitting is compatible with Knightsbridge's optional emergency kit (sold separately) for applications requiring maintained emergency lighting.\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\u003e1200mm\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\u003eMatt Black\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\u003e17\/20\/34\/36W\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\u003e1370\/1470\/1480\/1670\/1805\/1805\/2590\/2890\/2815\/2825\/3155\/3055lm\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-VVA4BK.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 select the wattage and colour temperature?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBoth wattage and CCT are adjusted via DIP switches on the LED driver before the fitting is powered on.
