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.
Recommended illuminance (Lux) | Areas and activities |
---|---|
40 | Corridors, walkways. |
80 | Change rooms, cleaners' rooms, internal stairs, loading bays, locker storage, toilets. |
160 | Bathing rooms, cafeteria and kitchen area, entrance halls, lobbies and foyers, waiting rooms. |
240 | Food preparation areas, medium woodwork, photocopying, training and seminar. |
320 | Meeting rooms, office work. |
400 | Fine woodwork. |
600 | Colour matching, drafting, fine machine work, inspection tasks, laboratories, painting. |
800 | Colour matching of dyes, fine inspection tasks. |
1200 | Extra fine bench work, graphic arts inspection. |
1600 | Jewellery and watch making. |
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.
On average, switching to LED lighting will:
Lighting a room you’re not using is a waste of energy.
Encourage your staff to switch off lights every time they exit a room or leave for the day. Add ‘switch off’ stickers near light switches and building exits.
Instead of relying on your staff to switch off lights, install a system that will do the work for you.
Motion detectors can save:
Though installing motion detectors and timers will cost money, they’re guaranteed to save money.
On average, installing motion detectors and timers will:
If you have multiple lights in a large area controlled by one switch, an electrician can section your lighting into zones. This allows you to only light areas that are being used.
A cost-effective way to lower the lighting levels in areas that are overlit, is by removing globes or lamps.
Natural light is free to use. To make the most of it:
