Primula is a series of outdoor lighting based on effective, non-glaring illumination, optimising the light from its source. Primula uses a combination of optical elements, also making use of stray light. The basic component is a symmetrical reflector transmitting light from the source directly to the top reflector, ensuring an effective distribution.The other optical element is white reflecting rings, utilizing the light which is not hitting the reflector. The stray light is collected and used by the white rings, without affecting the lamp’s efficiency. Primula’s top and base are constructed of heat-galvanized steel pipe, finished in flat, grey powdered lacquer. The shade is made of impact-resistant polycarbonate, and the white reflector rings are made of lacquered aluminium. The head is fastened to the base with a bayonet lock, allowing easy access to the light source.
