Head manufactured from milled steel and base in die-cast aluminium EN 44300 with very low copper content. Rod manufactured in stainless steel. As an alternative to the traditional polycarbonate (PC),used with diffusers to seal the lamp polymethylmethacrylate (PMMA) is used , so we obtain characteristics of high transparency, UV resistance and scratch resistance. No visible screws. Subjected to galvanic anodizing treatment divided into distinct phases: mechanical satin finishing, surface degreasing, anodic oxidation and final sealing. The product is painted following a continuous two step paint process (epoxy-based primer + polyester-based colour finish), which allows to generate a single thick protective coating which then generates aprotective barrier against atmospheric agents and UV rays.
