The luminaires are installed in 1999 and are in good condition. The light sources that
are used are 250W Mercury vapor powered by an electronic ballast. On average the
total power consumption per luminaire is 266W. All the light bulbs are exchanged
after approximately 20.000 hours every five years.
Retrofit with QL
To create a durable retrofit easy and fast the original parts of the luminaire are used.
The pictures of the open luminaires show the difference between the old non dimmable
ballast and QL dimmable electronic gear. In the picture where you can see the lamp (photo
below right) a tailored QL heatsink (silver) is added to dissipate the heat from the power
coupler and to position the lamp in the existing reflector.
New situation
In the new situation the luminaires in the following streets, Via XXV
Aprile, Via Europa,
Via della Repubblica in Oriolo Romano, are retrofitted from 250W Mercury vapor to QL
85W. The assembly or retrofit can be done very easily within the technical department or
by the installer. Below you can find the advantages of QL 85W systems compared to 250W
Mercury vapour.
