Available from 10W-83W

The Chalis post top range comprises high efficiency LED sources catering for both roadway and area lighting applications and is available in a range of power outputs to suit. The LEDs, lenses and electronic drivers are all housed within a contemporary and stylish, vandal resistant polycarbonate bowl and LM6 aluminium body with a number of features and benefits over that of a conventional post top lantern. 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).
