Hounslow Civic Centre

The London borough of Hounslow were looking for a 3 year maintenance free solution for their 3 storey Civic Centre office block, including walkways and meeting rooms, staffed throughout a 14 hour day.

The Requirement:

The client was passionate about finding a unique, sustainable, long term solution. Not only must it offer the same high quality light, it also needed to adhere to their rigorous policy of reducing their carbon footprint.

Prolite LED lighting was the obvious choice. The lights needed to offer the same light output, give a strong return on investment, reduce maintenance costs, have a high power factor, a low energy usage and have minimal recycling costs.

The Solution:

After a site evaluation, the Prolite technical team advised replacing the T12 lamps with 8ft T8 LED tubes, each using just 44W’s of energy. The life expectancy of the new lighting system will vastly reduce maintenance costs for the Civic Centre as replacements will not be required for at least 10 years.
