Technical description:
Downlight designed for use with 50 W dichroic lamps QR-CBC 51. It is made up of an aluminium sheet shell housing the optical assembly. The lamp is located on a die-cast aluminium ring directable through technopolymer universal joints (+/- 45° rotation with respect to the vertical and horizontal axes) - also permitting stablity of the angling system. The following accessories may be installed: coloured glasses, refractor for an elliptical distribution of the light flow, and honey-comb louvre.
Installation:
Recessed fitting: the shell is fixed to the false ceiling (hole dimensions 125 x 125 mm) through adjustable brackets on sliders. The perimetric rim is used as a ledge.
