Chalis Light Guide

Available from 24W-47W

The Chalis Light Guide post top range goes against the convention of using LEDs behind lenses. The conventional light engine has been replaced by a new low glare, comfortable ‘Light Guide’ that has been specifically designed to enhance user experience of the lit application. Paired with a sympathetic colour temperature of 3000K, the Chalis Light Guide is the perfect solution to high pedestrian traffic areas such as town centre market squares and high streets. Full tool free access is granted via the removable top spinning section which can also accommodate a range of externally mounted NEMA and Zhaga Book 18 sockets to allow full CMS or individual NEMA photocell operation.

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

Chalis Light Guide

Hereford Cathedral Close

The primary aim for changing the exterior lighting at Hereford Cathedral Close was to improve the reliability as the existing 45-watt Cosmo lamped lanterns were continually failing due to ballast and lamp failures, causing high ongoing maintenance costs.
