Available from 4W-19W

Via – a contemporary, highly robust and optically refined LED bollard with an abundance of features to overcome “real world” issues and problems.

The unique, self-contained Opti-Set feature from the Optio street light family, has been embraced and developed in to the Via bollard range providing on site, adjustable optic selection according to the application. A choice of square symmetric area or asymmetric footpath distributions are available in either 1750K (PC-Amber), 2700K, 3000K or 4000K colour temperatures and are all contained within the universal, modular IP66, IK10 head unit – You choose the distribution setting during install. To compound its flexibility, the on-board PowerSet feature (prevalent in all TRT products) provides yet more adjustability and on-site refinement by allowing a choice of power outputs to complement the chosen optical distribution. Integral photocell switching as well as standard mains switching is available and can even be retrofitted at a later stage if required.

Furthermore, when the vandal resistant access door is removed, it exposes sufficient space on an integral wooden back board to mount all necessary DNO cut outs and isolators. The ability to interface with in ground “sockets” as well as standard root and flange mounting methods, provides a totally universal single product for multiple applications with maximum flexibility build in as standard.

Physical, on-site, integral power adjustment within the lantern negates the need for any reprogramming device(s).
