Demi street fixture design: Lapo Grassellini
The result of research into aesthetics and technological innovation, Demi has a classic and elegant shape but is also equipped with the very best technical components. It is available with many types of arm and three different optics: street, rotosymmetrical and sidewalk. Demi is the perfect solution to the many requirements of street and urban lighting.

Sidewalk optic The sidewalk optic is ideal for pedestrian walkways and cycle paths, and can be combined with the street optic without interfering with road traffic; the optic system also helps to save energy by increasing spacing distances. Illumination class: S1

Street optic The street optic has been designed so as to concentrate most of the light it produces onto the road surface below, meaning that fewer installations are required and thus limiting maintenance and electricity costs. The optic system can be used to achieve high and uniform luminance on the road while limiting glare. Illumination class: ME3a
Road surface C2, q0=0.070 H= fixture height [m] B = road width [m] I= distance between poles [m] Lm= average maintained luminance [cd/m2] Uo= general uniformity of luminance UL= longitudinal uniformity of luminance TI= physiological glare index [%] Em= average illuminance [lx] Emin= minimum illuminance [lx]

Body Sheet aluminium cap, die-cast aluminium ring and body, tempered flat glass, aluminium optic, stainless steel screws and components which guarantee the fixture meets IP66 protection degree and insulation class II standards. The optical assembly can be opened from the bottom, using two stainless steel screws. Light sources Tubular metal halide lamps from 70 W to 250 W, high-pressure sodium lamps from 70 W to 250 W, and 70 W ellipsoidal

sodium lamp. In the rotosymmetrical version, metal halide lamp with G12 socket, from 35 W to 100 W. Emissions Available in street, rotosymmetrical and sidewalk versions. Power supply Electromagnetic wiring with capacitor and timed ignitor. Colours Satin-finish grey, anthracite grey or corten finishing.

Fixture installation and maintenance The simplicity of the fixture and its components means installation and lamp replacement procedures can be safely performed by a single operator.
Hooking the fixture onto the pole attachment using a fall-prevention system, for subsequent securing by means of stainless steel screws; adjusting the head on the horizontal axis.
Opening the optical assembly using two stainless steel screws; cutting off the electricity supply using a mechanical disconnection switch.
Releasing the parabolic optic hinged to the ring; easy lamp replacement.
