CONSTRUCTION The gear compartment is formed from heavy gauge zinc coated sheet of steel.Access to the control gear is via two wide openings covered by thermo resistant and high impact resistant polycarbonate doors which remain hinged to the body when they are open.Control gear is mounted on a “plug in” gear tray which is easily removable during the installation of the luminaire or during maintenance. The adjustable lampholder,enables optimum positioning of the lamp within the diffuser,thus permitting a wide range of distribution patterns.You may choose between an :aluminium diffuser or a polycarboante refractor.The high purity anodized aluminium reflector has a top vent which induces a convective self cleaning effect which minimises dirt build up on the inside surface of the reflector.The polycarbonate diffuser is the ultimate vandal proof.
