Project Overview

The Citadines on Bourke Melbourne is a 380 Apart' hotel  in Melbourne’s CBD, owned & operated by the global Ascott Limited. The building was completed in 2010 and is 25 stories tall including 1 level of underground car park.

The existing standard and emergency lighting in the back of house or service areas was twin T8 fluorescent tubes, which each drew 36W plus ballast.The existing lighting was on 24/7 with no lighting controls.

The Citadines team looked at more energy efficiency LED alternatives as they were experiencing a high proportion of emergency light failures, which contributed to high upkeep and maintenance costs.

Engineering Manager Chris Mitton came across enLighten Australia’s award winning Australian designed Chamaeleon LED luminaire as it was installed at a sister property Somerset on Elizabeth St Melbourne.

The lighting retrofit was implemented in 2 stages.The fire stair and undercover car park were completed in 2014, followed by the loading dock & ramps in early 2016. The main project drivers were to replace ageing and failing lights with energy efficient LED alternatives.

The site has two electricity service providers for different metred areas with a wide variation in tariffs according to usage volume. The undercover car park was one of the areas on the higher electrical tariff rate.


We have been impressed with the power savings and the robustness of the chamaeleon fixtures. The serviceability of the simple battery changeover for emergency versions has eliminated the need to call out an electrician as there is no need to disconnect the power.

The Solution

enLighten Australia’s Victorian Sales Executive, George Tzoutzidis, assisted with a site audit and product specification for the lighting levels to meet AS / NZS 1680 & Building Code compliance requirements.

In the fire stairs, a combination of standard & emergency 12 chip Chamaeleon lights were installed. enLighten's award winning Australian designed Chamaeleon light operates on a full light output of consumption of 32W, which drops to 8W in standby mode when no movement is detected in the area via the integrated microwave motion sensor. For low use areas such as fire stairs, the energy savings are significant, as the average rate energy consumption over 24 hours is under 10w.

In the undercover carpark for 38 spaces, a combination of permanently on 14 chip standard and emergency chamaeleon lights were specified for car park driveway areas.

For the loading dock entry, loading bays and ramp areas, replacement of existing light failures were proving particularly expensive due to the access difficulty. A combination of 12 and 14 chip permanently on chamaeleon lights were specified for these areas.

The permanently on Chamaeleon lights do not have a microwave motion sensor or a standby light output, with the occupancy sensor models installed over parking bays.

The installation contractor was Silk Electrical.
