Your guide to lighting
Light pollution is the human-made alteration of outdoor light levels from those occurring naturally. When we over-light, fail to use timers and sensors, or use the wrong colour of light, we can negatively affect many parts of our world, including migratory birds, pollinators, sea turtles, and mammals, including humans.
The good news is that light pollution, unlike many other forms of pollution, is reversible, and each one of us can make a difference! Just being aware that light pollution is a problem is not enough — we need to take action.
01
OUTDOOR LIGHTING
Utilise outdoor lighting responsibly by illuminating only what is necessary, at the required brightness, and only when needed.
02
SHIELDED LIGHT FITTINGS
When installing new light fittings, ensure they are fully shielded, directing light exclusively downwards and avoiding upward or sideways illumination.
03
ENERGY EFFICIENT BULBS
Opt for energy-efficient bulbs, using the minimum wattage required and minimizing the number of installed lights.
04
WARM LIGHTING
Select warm yellow-white bulbs with a color temperature not exceeding 3000 K for replacements. Preferably, use orange lamps (2200 K) and avoid harsh blue-white bulbs (4000 K or greater).
05
MOTION SENSORS
Turn off lights when unnecessary, employing timers or motion sensors to ensure illumination only when required. Exterior lights should be off between 11 pm and 5 am, preferably from 10 pm to dawn.
06
CURTAINS & BLINDS
If interior lights spill significant light to the exterior, use blinds or curtains to minimise the impact on the surrounding environment.
