Outdoor pendant luminaire with high visual comfort (G4) down light street optic, designed to use LED lamps. The optical assembly and the pole attachment system are made of EN1706AC 46100LF aluminium alloy and subjected to a multi-step, pre-treatment process, in which the main phases are degreasing, fluorozirconation (a protective surface film) and sealing (with a nano-structured silane layer). The painting stage consists of a primer and a liquid acrylic paint, cured at 150 °C, with a high level of weather and UV ray resistance. Can be adjusted +/-15° relative to the horizontal axis, and 360° about the vertical axis. 4 mm thick sodium - calcium glass diffuser. Optical assembly and lid fixed together by a hinge and two clips for tool-free opening. High level IP66 protection is guaranteed by the 50 Shore black silicone gasket placed between the two elements. Steel lid automatic retention system. Optical assembly complete with decompression valve, to clear the internal vacuum for easy opening. Complete with circuit having Neutral White monochrome LEDs and silver aluminium reflectors. LEDs can be substituted in groups of 12. DALI electronic control gear. Control gear, connected using quick-couplings, can be removed using clips. Driver with automatic inner temperature control system. Driver with 3 different operating profiles, without the aid of external controls, fixed profiles at 100% corresponding to three different lumen outputs. Profiles can be selected using microswitches. Replaceable control gear unit. Die-cast aluminium fixing system with anchoring system to stainless steel wire. Stainless steel anti-fall safety system. There is no light dispersion into the upper hemisphere above this luminaire in the horizontal position (in conformity with the strictest standards for the prevention of light pollution). All external screws are made of stainless steel.

Wiring
The product is powered by cables from a pre-wiring box with 4-pin terminal board and resistance
to mains voltage spikes up to 4KV (Varistor). Product perfect watertightness at the power cable entry point
is guaranteed by the PG M24x1.5 mm cable gland made of thermoplastic material, thrust ring and rubber closure cap, achieving insulation class II.
