Lighting Matters were fortunate enough to be invited back to St Pauls Cathedral in Melbourne to provide the second part to their lighting upgrade.
Part 2 of the lighting upgrade involved replacing a number of 300W PAR lamps with appropriate LED light fittings to provide a dramatic reduction in energy consumption but as well as an increase in light levels.
There were 6 points through the hall that housed these 300W spot lights, with 22 of these running at all times to light up the space you can imagine the power bill running 6.6kW of lighting load at all times, besides the significant maintenance cost of the 4000 hour bulbs.
Given the mounting height a special elevated working platform using dual fuel was required.
Each set of these existing lights were replaced with a vertically mounted 3 circuit track light system, housing 33W high CRI and high efficacy Nordic LED track lights with VERY narrow beams down to 10 degrees. We replaced every 3 sets of 300W lights with 4 of these to achieve the increase in light output, carefully focused on certain areas of the cathedral to illuminate the back wall, the alpha and omega symbols, the choir area and the speakers positions.
The result of changing these lights was a dramatic reduction in power consumption, from 6600W to less than 1000W. A full 5 year warranty, significant reduction in heat output, significant reduction in maintenance costs and a massive increase in light output highlighting important parts of the Cathedral.
Special thanks to Dennis Electrical Contractors in Victoria for the installation support.
