St. Paul’s Cathedral in Melbourne is arguably one of the best buildings in Australia, such beautiful design, long lasting and filled with pride. They did however have an issue with lighting as may older buildings do. As such old technology has become obsolete and often causes many issues, especially in terms of re-lamping failed lights and of course the huge maintenance cost to keep them running.
Throughout St. Paul’s more than 350 fixtures with incandescent PAR38 lamps are housed, drawing more than 100 watts each the hourly power bill is in excess of 30kW of lighting alone, which even at a low rate of electricity cost works out to more than $4.50 an hour to run, with excessive heat included and maintenance and re-lamping costs these PAR38 lamps are literally burning through money.
An added complexity was the requirement that the new LED lamps selected were to work with the existing Dynalite automation dimming system and due to this the Philips 14.5W LED PAR38 Airflux lamp was selected for use thanks to it’s compatibility, narrow beam angle and warm colour temperature. Here are the photo’s pre installation.
