THE BACKGROUND
Energy Cost Attack was the successful bidder to provide Baby Bunting with a new generation of LED high bay lighting, in there Store at paramatta Roa, Auburn. The store was previously operated by Hobby Norman and the Metal halide lights had been running for many years, resulting in uneven light levels and in some parts of the store, light was too weak to encourage a retail customer to make a buying decision.
THE PROJECT
The project was undertaken after business hours. 
The electrician worked through the night with his ground support team keeping him supplied with new fittings and removing old fittings, whilst he worked from the compact scissor lift. The install team required three nights to undertake the full change over of old lights to the brilliant new LED High Bay lights, and to make good on waste removal.
Energy cost attack ensured that the Mercury filled Metal halide light globes was separated and processed by CMA Ecocycle.
THE RESULT
ENERGY SAVED is 67%….. by conversion of Metal Halide lights to LED lights.
MAINTENANCE SAVED is 100%….no maintenance required for about 10 years.
RETURN on INVESTMENT ….60%
What is more important, the inventory shelves look so much brighter and more inviting. The Before and After shots below demonstrate the clarity and evenness of LED light.
