Siteco has developed High Definition Primatics (HDP) for spaces having high demands for the restriction of direct glare. Luminaires with HDP technology reach an UGR value of 19 and are therefore highly suitable for uses in rooms with high glare-restriction requirements. As well as for uses in office areas, HDP luminaires are suited for communications areas, workshops, service rooms, libraries, catering areas, waiting zones, classrooms and lecture halls. As well as the Novaluna, the Siluette interior luminaire and the Modario trunking system are available with HDP technology. A variation of the Comfolight has also been equipped with HDP technology, having a louvre with prismatic lamellae.
