Switch off your lights
Do you know that 50% of light pollution is produced by
light that no one needs? Turning off unnecessary lighting is
one quick and simple way to reduce light pollution. Not
only this, but it can help reduce your energy costs too.
Keep your curtains closed
By keeping your curtains or blinds closed, light can be
contained inside your property and so minimises the risk of
it emitting to the night’s sky.
LEDs
LED lighting can sometimes emit less pollution than
other types of bulbs however it’s all about the quality.
Well designed LED lights can reduce the amount of
wasted light the bulbs emit but it’s best to find options that
have a CCT of <3,000 to minimise blue emission and has
adaptive controls including dimmers and timers.
Add a shield
Shielding your lights, especially those that are outside,
can reduce light pollution. It also keeps light directed
where it needs to be. There are a variety of different light
shields you can use including solid caps and lightshades.
Keep your light pointed down
It is important to direct light downwards, not up into the
sky, so that light does not spill beyond where is it needed.
If the light is visible from beyond your property then it is
doing more harm than good.
