Project scope

The lighting upgrade project involved upgrading lights throughout their entire store and office space:


  • Replacement of 27 x 36W T8 fluorescent tubes with 27 x 11W LED tubes.
  • Replacement of 6 x 400W mercury-vapor high bays with 6 x 115W LED high bay lights.
  • LUX measurements in each space to confirm minimum lighting standards.

Also, 4 non-working fluorescent tubes were replaced, and a high bay was installed for additional lighting at the customer’s request. These weren’t claimable under REES.


  • The project is expected to deliver an estimated 9,315 kWh in electricity usage savings annually2, equating to estimated annual savings of about $2,795.^
  • The building now has improved lighting levels and a reduction in maintenance/ replacement costs as the new LED lights have a full product and installation warranty of three years. The LED products installed have x1.8 life expectancy when compared to traditional linear fluorescent tubes, and up to x2.5 when compared to legacy high bay lights.

All prices include GST.

1Includes costs such as installation, product costs, non-working lights and equipment hire.

2Savings based on the difference between Foodbank’s previous and upgraded lighting products operating at an average of 3,450 hours annually.

3Estimated time for Foodbank to save the project cost (after REES rebate) with respect to the electricity cost savings.

^Electricity cost savings: based on Foodbank’s electricity usage savings multiplied by its electricity tariff at time of installation (30c/kWh).
