Strategies To Curb Light Pollution And Its Adverse Effects

Light pollution is a growing problem, but there are simple, low-cost changes that can be made to limit how much you contribute to it. For example, only use outdoor lights when necessary, and use the lowest possible light levels. Avoid blue light at night, and instead, use warm light sources. Closing curtains or shades at night can also help to reduce light pollution.

Only use outdoor lights when necessary

One of the top lighting principles to keep in mind is to only use outdoor lights when necessary. Adding outdoor light has become so easy that anyone can order and install decorative lights for their terrace or patio. However, just because you can, doesn't mean you should. Only light what truly needs illumination. You likely do not, for instance, need to shine a light from dusk to dawn over your backyard.

The simplest action you can take is to switch off unnecessary lights. This is the cheapest, easiest, and most effective method of dealing with the problem. You can do this when you are about to sleep, or there is no activity outside the house.

You should also avoid the temptation to overlight. Be strategic about where light goes—you want to aim it so it hits where illumination is needed. Lighting that is going upward into the night sky is waste. Look for shielded fixtures, which have a cap at the top so no light emits upward from the bulb and are angled to only light below the fixture (and not above it). Fixtures that meet these standards are readily available at hardware stores and online.

Direct lights just where you need them. Always avoid blue light at night, and instead, use warm light sources for any outdoor lighting. Don't turn night into day. Use a warmer colour temperature that is more appropriate for nighttime.

Use the lowest possible light levels

One of the most important things to keep in mind when trying to limit light pollution is to use the lowest possible light levels. This means avoiding the temptation to overlight and being strategic about where you place your lights. Only light what truly needs illumination and avoid lighting that goes upward into the night sky. Fixtures that meet these standards, known as shielded fixtures, are readily available at hardware stores and online.

When choosing outdoor lighting, opt for warm light sources instead of blue light. This will help create a more natural nighttime environment. You can also direct lights just where you need them, rather than letting them shine out of windows. This can be as simple as closing your curtains or shades at night to block out the light.

In addition to strategic placement and warm lighting, it's important to only use outdoor lights when necessary. Adding decorative lights to your patio or terrace may be tempting, but it contributes to light pollution. Instead, consider the ground surface and choose more reflective options to maximise the impact of your lighting.

By following these guidelines and using the lowest possible light levels, you can significantly reduce your contribution to light pollution. Not only will this help combat lighting pollution, but it will also save energy and reduce costs. Remember, when it comes to lighting, less is often more.

Direct lights to where you need them

Directing lights to where you need them is a great way to reduce light pollution. Avoid the temptation to overlight and be strategic about where light goes.

Only use outdoor lights when necessary. Adding outdoor light has become so easy, anyone can order and install decorative lights for their terrace or patio. But just because you can, doesn’t mean you should. You likely do not, for instance, need to shine a light from dusk to dawn over your backyard.

Use the lowest possible light levels and consider the ground surface, since some are more reflective than others. Use warm light sources for any outdoor lighting. Don't turn night into day – use a warmer colour temperature that is more appropriate for nighttime.

At night, instead of letting the glow of your lights and your television blares out of the window, close your curtains or shades.

Avoid blue light at night

To avoid blue light at night, use warm light sources for any outdoor lighting. This means using a warmer colour temperature that is more appropriate for nighttime. Blue light can be disruptive to sleep, so it's important to limit exposure in the evening. If you're watching TV at night, close the curtains or shades to prevent the glow of your screen from contributing to light pollution.

You can also make changes to your indoor lighting to reduce blue light exposure. Try to avoid using bright, blue-toned lights in the evening and opt for warmer, softer lighting instead. This can help signal to your body that it's time to wind down and prepare for sleep.

There are also settings on electronic devices that can help reduce blue light exposure. Many smartphones, tablets, and computers have a "night mode" or "blue light filter" setting that adjusts the colour temperature of the screen. This can help reduce eye strain and improve sleep.

Finally, it's important to be mindful of the impact of outdoor lighting on the environment and wildlife. Light pollution can disrupt the natural cycles of plants and animals, so it's crucial to only use outdoor lights when necessary and to direct them where they're needed. By following these tips, you can help reduce light pollution and its impact on the environment and your health.

Close curtains or shades at night

Closing curtains or shades at night is one of the simplest ways to limit light pollution. By doing this, you can prevent the glow of indoor lights, such as lamps and televisions, from shining out of windows and contributing to light pollution.

This is a straightforward and low-cost change that anyone can make, whether a homeowner or renter. It is an effective way to reduce your impact on light pollution, alongside other measures such as only using outdoor lights when necessary and switching off unnecessary indoor lights.

When using outdoor lighting, it is important to be strategic about where you direct the light. Aim it only where illumination is needed, and avoid lighting that goes upward into the night sky. You can also look for shielded fixtures, which have a cap at the top to prevent light from emitting upward, and are angled to light only below the fixture. These fixtures are widely available at hardware stores and online.

Additionally, consider the type of light you are using. Avoid blue light at night, and opt for warm light sources instead. This helps to maintain the natural darkness of the night sky and creates a more appropriate ambiance for nighttime.
