Technical Data
last update: 25/08/2026Description
Street optical system designed to use sodium-vapour lamps 100W with power limiter. It is made up of optical assembly, arms and flanges. The hemispheric optical assembly is made of turned aluminium sheet (thickness 2mm) subjected to phosphochromatic and liquid acrylic painting treatments. The upper section is equipped with a junction to the arm that permits levelling the bowl. The lower section is enclosed by a tempered protection glass with non-staining silicone closing gasket subjected to post-cooling 200°C oven treatment. The glass is coupled to the optical assembly by means of stainless-steel fixing screws for quick snap closing and quick opening by 90° rotation with a tool. A retention cable prevents the glass from falling during installation and maintenance. The optical assembly is made up of a polished 99.9% superpure aluminium reflector. The ceramic lampholder comprises an antiloosening device for the lamp. The galvanised-steel powder-painted supporting arm is complete with two die-cast aluminium flanges for wall application. The flanges and the arm are designed to let the cables needed for wiring pass through.

Wiring
The phased control gear is equipped with double-insulation and 100W-to-70W power limiter. It is made up of an extractable component-holding metal plate that is insulated from the bowl by means of captive screws and spacers and includes fast-fitting connectors for easier installation and use.
