The Project

A large school in the northern suburbs of Melbourne, with students from year 7 through to year 12, Epping Secondary College undertook a lighting upgrade across the entire school. Following an energy usage analysis, significant energy and maintenance savings could be found by upgrading to energy-efficient LED lighting to replace the existing lighting. The quality of light would also be improved.

Epping Secondary


Throughout the classrooms, library, auditorium, basketball court, offices and hallways the existing lights were upgraded to LED tubes and LED highbays. A substantial reduction in total lights was achieved, replacing 2,224 with just 1,133.

The superior light globes create a more comfortable learning and working environment for the students and teachers.

A little known fact is that the LED’s produce much less heat allowing a further contribution to comfort and savings through less cooling required.

Epping Secondary


The exterior lighting covering walkways, courtyards and large open areas consisted of a mixture of metal halides, incandescent, halogen and CFL globes. These were replaced with LED flood, LED tube and LED bunker light fittings.

The higher-performing replacements allowed for fewer globes, with the 277 existing lights replaced by only 212.

Key Benefits of the Lighting Upgrade

  • Rebates of $38,400 achieved through Government incentive schemes.
  • A total of 2,501 lights were replaced with 1,345 energy-efficient LEDs.
  • Longer lifetime of LED expected to deliver maintenance savings of $7,760 p.a.
  • Energy usage reduced by 60% saving an expected $31,380 p.a.
  • Total payback period of just 3.3 years.
