Circa Light Guide
Available from 23W-47W
The Circa Light Guide luminaire 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 The conventional light engine has been replaced by a new low glare, comfortable ‘Light Guide’ that has been specifically designed to enhance user experience of the lit application.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 Circa Light Guide is the perfect solution to high pedestrian traffic areas such as town centre market squares and high streets. The Circa luminaire range can 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).
PowerSet feature available; field adjustable, integral power output selection device.
International Dark-Sky Association approved. Compliant when using a colour temperature of 3000K or below when mounted horizontal to the carriageway/footway.
