The Orac Luxxus C351 coving features a gentle upward curve which projects 17.5cm into the room, and has an 8cm height. This shallow cup profile has been designed to give an excellent spread of light onto the ceiling. Customers seeking bright illumination should select our T5 tubes, and IL light plates for optimum performance. If you are using the C351 indirect light coving in conjunction with central ceiling lights you may prefer to choose save money by using the lighting string and low energy bulbs. When being using with Orac lighting systems please ensure that there is at least 15cm (or ideally 20cm) of space above the C351 cornice to allow space for installation of bulbs, and adequate light dispersal. We recommend that the ceilings above the C351 coving profiles are painted white to allow optimum lighting performance in your room. If you have used this product previously you may recall the Orac Myline brand name. Each 2 metre indirect light coving profile is manufactured from a high quality man-made polyurethane, and is supplied with undercoat pre-applied to save you time when installing. We recommend all lengths are stuck to the wall with FDP500 DecoFix Pro, and also mechanically fixed to bear the load of any lightplate installed within. All butt joints and mitres require Extra Fix adhesive. Length: 200cm Height: 7.4cm Width: 17.3cm
