The switching mechanism is housed in the driver compartment inside the white aluminium body, which measures 48mm wide and 63mm deep along the 1200mm run.\u003c\/p\u003e\n\u003cp\u003eDesigned for ceiling or suspension mounting in offices, studios, classrooms and commercial spaces where glare control matters, the Viiva carries a UGR19 rating that keeps direct glare below the threshold where it causes discomfort for screen-based work. The 90-degree beam angle spreads light across desks and worksurfaces without creating harsh shadows or pooling. Surface mounting uses the integrated brackets on the back of the housing; suspension mounting requires optional cable kits.\u003c\/p\u003e\n\u003cp\u003eThe aluminium construction in a powder-coated white finish gives the fitting a 1.1kg weight and keeps the profile low against white or light-toned ceilings. The selectable wattage range means a single fitting type can be stocked and adjusted on-site to match the lumen requirement of the room, from 1260lm at 17W\/3000K up to 2875lm at 36W\/4000K. The IP20 rating limits the fitting to dry indoor environments, and the Class I construction requires an earth connection.\u003c\/p\u003e\n\u003cp\u003eKnightsbridge produces an emergency conversion kit compatible with the Viiva range, allowing the fitting to act as emergency lighting where building regulations require maintained or non-maintained emergency operation. The kit is sold separately and linked in the Downloads section.\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\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\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\u003e1260\/1355\/1365\/1515\/1630\/1625\/2460\/2710\/2640\/2585\/2875\/2780lm\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-VVA4W.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/niori.co.uk\/products\/emergency-kit-for-viiva-linear-fittingsc\"\u003eEmergency Kit\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow are the wattage and colour temperature selected?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBoth settings are adjusted via switches inside the driver compartment before installation.
