Quarterlite lighting reduces energy consumption

Clear Channel Outdoor has demonstrated that it is possible to reduce energy consumption by more than 65 per cent by using Luminanz Manufacturing's Quarterlite technology.

Clear Channel Outdoor, which supplies outdoor advertising solutions, replaced conventional strip lights in 20 advertising boxes with Quarterlite low-energy lighting for illuminated signs in a pilot scheme in London and Liverpool, UK.

The trial showed that the light-emitting diode (LED) technology lit the boxes more effectively and energy consumption calculations demonstrated cost and energy savings.

For the trial, three rows of five Quarterlites were substituted for the three fluorescent tubes in each advertising box.

This reduced the power consumption of each box from 186W to 66W.

Each Quarterlite box saves over 489 kWh of power and 211kg of carbon dioxide per year.

The system was simple to install and will provide maintenance-free lighting for over 10 years.

Quarterlites produce an even white light for adverts that stands out in brightly lit city-centre environments, does not corrupt skin-tone images, and does not produce the light and dark streaks associated with some traditional lighting systems.
