“ We were looking for the best possible solution.

For us, it had to be white light and CosmoPolis with

Xtreme Lumistep Drivers proved to be the winner”

Diego Ardizzone, Designer, ING


Following the renovation of a large town area, the Cenate Sotto

municipality wanted to replace lightpoints covering an area of

4,500 km2 . To help them choose the best quality light with the

highest energy savings they enlisted the help of Gewiss, a leading

manufacturer of fully integrated electrical installation and lighting

systems and lighting specialist Diego Ardizzone.

The challenge

Light influences the way people feel about city life, particularly

at night when artificial lighting becomes part of the architecture.

The district authority wanted to replace the unattractive, yellow

sodium lighting with better quality white light to save energy and

enhance the city’s ambience.

The solution

On the recommendation of Mr Ardizzone, the Cenate Sotto

municipality chose CosmoPolis for its warm white light and the

dramatic affect it has on night-time ambience. A total of 620

Avenue3 Gewiss luminaires equipped with Cosmopolis were

used to upgrade the fixtures and obsolete lightpoints.These are

controlled by PHILIPS HID DV XTREME LUMISTEP to switch the

light points on and off, dimming light levels by 50% at night to save

energy and avoid light pollution.


The city now benefits from the highest quality light levels, while

night-time dimming guarantees energy savings of 40%. The solution

saves € 32,000, annually, giving a pay-back time of less than 4 years.

The 80,000 hour maintenance interval also minimises costs and

the ballasts also come with an 8-year commercial warranty.
