The highly technical design of Chalfont strictly controls the spillage of upward light and distributes light over the required area in a square or asymmetric light distribution, according to individual requirements.

Designed for energy efficiency, Chalfont’s optical system provides effective control of the lamp flux, achieving high light output efficiency and a quantifiable performance advantage unrivalled by other optical systems. Unlike conventional luminaires, the geometry of Chalfont’s reflecting surfaces results in light only having to be reflected once, maximising luminaire efficiency.
