Reasons to Keep Outside Lights On at Night
Leaving your outdoor lights on throughout the night can provide numerous benefits for your home and family. Here are some key reasons to consider keeping your exterior illuminated:
Increased Home Security & Burglar Deterrence
One of the primary motivations for leaving porch lights on at night is to deter potential intruders. A well-lit property sends a clear message that the home is occupied and security-conscious. Burglars and other criminals often prefer to target darker homes, as they provide more opportunities to hide and evade detection. By keeping your outdoor lights on, you make your property a less appealing target, significantly reducing the likelihood of break-ins and vandalism.
Greater Visibility and Safety
Illuminating your home's exterior not only enhances security but also improves visibility and safety for you, your family, and your guests. A brightly lit porch, walkway, or driveway ensures that everyone can navigate safely, avoiding potential tripping hazards or obstacles. This is especially important for elderly individuals or those with mobility issues. Additionally, if you or a family member arrives home late at night, a well-lit entrance allows for a more secure and comfortable arrival.
Welcoming Expected Visitors
Leaving your porch light on can serve as a warm and welcoming gesture for expected visitors, such as friends or family members. It helps them locate your home more easily and provides a sense of comfort and hospitality. This is particularly helpful if you're expecting deliveries or service providers, as a lit porch signifies that someone is home to receive them. Moreover, if you have children who may be returning home late, a porch light left on can provide a reassuring beacon to guide them safely to the door.
Reasons to Turn Outdoor Lights Off When You Go to Bed
While there are benefits to leaving your outdoor lights on, there are also compelling reasons to consider turning them off before you go to bed. Here are some factors to keep in mind when deciding if it's a good idea to leave your outdoor lights on.
Reduced Energy Consumption and Costs
Leaving your outdoor lights on all night can significantly impact your energy consumption and electricity bills. In Australia, the average cost per kWh is around 30 cents, which means that running a single 60-watt porch light for 12 hours every night could add over $65 to your annual energy costs. By turning off your lights when they're not needed, you can reduce your energy usage and save money on your utility bills.
Minimising Light Pollution
Light pollution is an increasingly common problem in urban and suburban areas, and leaving outdoor lights on all night can contribute to this issue. Excessive artificial lighting can disrupt the natural cycles of wildlife, interfere with astronomical observations, and negatively impact human health by disrupting our sleep patterns. By being mindful of your outdoor lighting habits and turning off lights when they're not essential, you can help reduce light pollution in your community.
Avoiding Attracting Bugs
If you've ever spent time outdoors on a summer evening, you know how quickly insects can be drawn to artificial light sources. Leaving your porch light on all night can attract a variety of bugs, including moths, mosquitoes, and flies, which can be a nuisance for you and your guests. To minimise the number of insects around your home's entrance, consider turning off your outdoor lights when they're not needed or using bug-repellent bulbs.
Maintaining Good Sleep
Exposure to artificial light at night can disrupt our natural sleep-wake cycle, making it harder to fall asleep and stay asleep. If your bedroom windows face your outdoor lights, leaving the light on can interfere with your body's production of melatonin, a hormone that regulates sleep. By turning off your outdoor lights before bedtime, you can create a darker, more conducive environment for a good night's rest, promoting better overall health and well-being while avoiding the downside of leaving your lights on.

Finding the Right Balance for Your Outdoor Spaces
To strike a balance between the benefits and drawbacks of leaving your outdoor lights on all night, consider implementing these strategies:
Use Motion Sensor Light Fixtures
Installing motion sensor lights around your property can provide illumination when it's needed most while reducing energy consumption and light pollution. These lights will automatically turn on when movement is detected within a certain range, typically between 5 to 20 metres, and then turn off after a preset period of inactivity. Motion sensor lights are an excellent choice for driveways, walkways, and other high-traffic areas around your home.
Set Lights on Timers
If you want to keep your outdoor lights on for a specific period, such as from dusk until bedtime, consider using timers. These devices allow you to program your lights to turn on and off at designated times, ensuring that your property remains well-lit when needed without leaving your lights on throughout the entire night. Some smart lighting systems even allow you to control your lights remotely using your smartphone or voice assistant, providing added convenience and flexibility.
Choose Energy-Efficient Bulbs
When selecting bulbs for your outdoor lights, opt for energy-efficient options like LEDs or compact fluorescent lamps (CFLs). These bulbs use significantly less energy compared to traditional incandescent bulbs, which can help reduce your electricity costs and environmental impact. In Australia, an LED bulb can cost as little as $5 per year to run, compared to over $20 for an incandescent bulb, providing a cost-effective option if you choose to leave your outdoor lights on at night. Additionally, LEDs and CFLs have longer lifespans, meaning you won't need to replace them as frequently.
Be Mindful of Neighbours
When positioning and aiming your outdoor lights, be considerate of your neighbours to avoid issues that come from leaving lights on continuously. Avoid installing lights that shine directly into their windows or illuminate their outdoor living spaces, as this can be disruptive and inconsiderate. If you have concerns about your lighting affecting your neighbours, have a friendly conversation with them to find a mutually agreeable solution. In some cases, using lower-wattage bulbs, adjusting the angle of your lights, or installing shields can help minimise the impact on neighbouring properties.
By implementing these strategies, you can enjoy the benefits of a well-lit exterior while minimising the negative aspects of leaving your outdoor lights on all night. Finding the right balance may require some trial and error, but with a little effort and consideration, you can create a lighting plan that works for your home, your family, and your community.
