Centro Quadro

Centro Quadro (QU3)

The Centro Quadro is manufactured from shatterproof vandal resistant polycarbonate, the range offers the tough and robust construction of our utility range with the versatility and design of our office and commercial fittings.

With the inherent flexibility provided in all ASD’s lighting ranges, CENTRO offers a choice of operating and lamp / LED options.

This range’s eye-catching design is complemented by a host of features to speed installation time. By incorporating a ‘first fit’ base with fast fit connector block, the fitting’s gear tray can be ‘snapped’ in to place in seconds. The unit’s diffuser clips easily on and the Twist-Lock fascia simply rotates into position.

The CENTRO range is available in Circo, Maxi Circo, Quadro, Trio and Ovo options with an ambient Halo effect also available, which not only provides forward illumination but also a decorative halo back light. As standard this is achieved with a clear lens or can be provided in a range of colours: blue, red, green or amber.
