Product code ST04 Walky ST04: Rectangular optic assembly 270x90mm – AL optic – Neutral White – 24Vdc Technical description: Luminaire for walkways designed to use LED lamps with a high efficiency value. Ceiling, wall-recessed and pole-mounted installation. It consists of an optical assembly with an IP66 protection rating and an outer casing or wall-mounted base to be ordered separately. The optical assembly and base are made of aluminium alloy treated with powder paint, which provides a high level of resistance to weather and UV rays. Plastic closure guard at the rear of the optical assembly. Complete with plastic cable gland and outlet cable. Transparent sodium-calcium tempered safety glass. Luminaire with no visible screws and an anti-vandal system that uses an opening key to access the rear wiring compartment (supplied in the package). All external screws used are made of A2 stainless steel. Installation: Wall-recessed installation with a plastic outer casing to be ordered separately. Disposable polystyrene formwork for creating the outer casing housings for installations in concrete walls that are then plastered or finished with bricks so the end surface is flush with the optical assembly. Wall-mounted installation requires an aluminium base to be ordered separately. Pole-mounted installation requires a pole to be ordered separately.
