There’s an Australian standard (AS/NZ 1680.1:2006) that determines what illuminance light levels are required in certain work areas.
To measure your current light levels, hire or purchase a quality light meter and compare the results with the recommended illuminance in the following table.
The goal to reducing your lighting consumption is to optimise your existing system to get the maximum efficiency out of it.
LED lighting is more than 60% efficient than fluorescent and halogen lighting, and significantly reduces your maintenance costs.
A LED downlight can last up to 50,000 hours, which is 25 times longer than a halogen light.
Not only are LEDs more efficient, but they’re also safer. Halogen downlights can heat up to 370°C which can be a fire risk and impact your air-conditioning costs.
The cost of switching to LED can take less than two years to pay for itself.
