B209

Fitting designed for street optic that uses metal-halide CDO-TT lamps 100 W and sodium-vapour lamps HST. The hemispherical optical assembly is made of turned sheet aluminium (thickness 2 mm) subjected to phosphochromatisation treatment with double primer, passivation at 120° C, liquid acrylic paint, baking at 150° C. The upper section of the body is equipped with a junction to the supporting arm that permits levelling the bowl. The lower section is housed by a black transparent silk-screened hardened protection glass 6 mm thick. For perfect tightness a black non-staining silicone gasket 50 Shore A is used that was subjected to post-cooling treatment (in the oven) 6÷10 h at 200° C. The glass is coupled to the optical assembly by stainless-steel fixing screws for fast opening (90° rotation with tool) and fast click closing by pressure. A steel retention cable (diam 1.2 mm) prevents the glass from falling off during maintenance and installation work. The assembly houses a polished 99.9% superpure aluminium reflector. The ceramic lampholder is equipped with an anti-loosening device for the light source. The cable clamp is made of black EPDM 65±5 Shore A rubber. No light flow is emitted from the upper section of the fitting. All screws are made of stainless steel (A2).

The optical assembly is applied by means of a 48-mm arm to the pole or the wall.;

Part numbers B208-B209-B210-B211-B212 can be installed on an arm, model number 1050 positioned downwards. They can be used as substitutes for attachments with globes that are already installed, in order to comply with even the strictest laws against light pollution
