What is Light Pollution?

Light pollution is a type of environmental pollution caused by the excessive and improper use of artificial light. It is usually caused by outdoor lighting such as streetlights, car headlights, and building lighting, but can also be caused by indoor light sources such as computer monitors and televisions. Light pollution not only affects the environment, but can also have negative effects on human health. Too much artificial light can disrupt our circadian rhythms, or our body’s natural sleep-wake cycle. It can also cause light-induced headaches and eye strain.

Light pollution – or artificial light at night – is an issue that has been gaining attention in recent years due to its potential impacts on both the environment and human health. It occurs when too much outdoor lighting is used in an inappropriate manner or for too long a period of time. Common sources of this type of environmental contamination include street lamps, parking lot/shopping mall lights, exterior lights found on most homes/businesses, neon signs and other forms of advertising signage.

The consequences associated with this form of contamination are far reaching; it washes out starlight in the night sky making it difficult to observe celestial objects; it disrupts ecosystems by interfering with animal migration patterns; it affects human health through disruption to our circadian rhythms which regulate sleep-wake cycles; it causes headaches and eye strain due to overexposure to bright lights; and finally it wastes energy resources leading to higher electricity bills for consumers as well as increased carbon emissions into the atmosphere from power plants producing electricity for these lights.

In order to reduce its impact on both humans and wildlife alike we must take steps towards reducing our reliance on artificial lighting at night while ensuring that any necessary outdoor lighting is used responsibly so that its effects are minimized wherever possible. This includes using motion sensors so that lights turn off when not needed as well as using shielded fixtures which direct all emitted light downwards instead of upwards where it contributes more significantly towards skyglow (the brightening effect seen in urban areas). Additionally we should strive towards using LED bulbs whenever possible since they produce less heat than traditional incandescent bulbs while still providing adequate illumination levels without wasting energy resources unnecessarily

How does Light Pollution Affect the Environment?

Light pollution has a wide range of environmental impacts, from disrupting the mating and feeding patterns of nocturnal animals to reducing visibility of stars in the night sky. animals such as moths, bats, frogs, cats and other wildlife species are affected by light pollution which can alter their behaviors, foraging areas and breeding. Unshielded lights can cause both astronomical and ecological light pollution with sky glow from cities disrupting distant ecosystems. Tall structures with lighted areas can also contribute to this problem. The impressive increase in artificial lighting at night has put light pollution on the list of threats to ecosystems with many studies showing its negative effects on wildlife. Light pollution affects many animals that rely on natural cycles of darkness and light to survive making it an important issue for conservationists to consider when managing habitats.

What Can We Do to Reduce Light Pollution?

One of the most effective ways to reduce light pollution is to use outdoor lighting fixtures that are fully shielded and directed downward. This will help minimize the amount of light that is scattered into the night sky, while also saving money on energy costs. We can also take steps to reduce indoor light pollution by turning off unnecessary lights and using low-energy LED bulbs. Dimmers, motion sensors and timers can help further reduce average illumination levels and save even more energy. Outdoor lighting fixtures should be capped with a solid top over the bulb in order to shield it from scattering into the night sky. Additionally, shades or covers should be used to force any remaining light downward instead of up into space.

In general, we should strive to minimize our use of decorative lighting as much as possible in order to reduce light pollution. Domestic security lights should provide only enough illumination for a single property rather than half a street or more; this will help conserve energy while still providing adequate safety measures for homeowners. LEDs and compact fluorescents (CFLs) are great options for reducing energy consumption; however, warm-colored bulbs should be used instead of cool-colored ones in order to prevent further disruption of natural ecosystems at night time.

The 5 Principles for Responsible Outdoor Lighting provide an excellent framework for reducing light pollution while still maintaining safety standards: 1) Use only necessary lighting; 2) Shield all outdoor lights; 3) Minimize glare; 4) Reduce blue-rich white LED sources; 5) Turn off unnecessary lights during nighttime hours when not needed or required by law enforcement agencies or other organizations responsible for public safety purposes. By following these principles, we can create a better quality of life not just for ourselves but also all living things around us!


Light pollution is an ever-growing problem, but there are steps we can take to reduce it. By using shielded and downward-directed outdoor lighting fixtures, energy-efficient LED bulbs, and turning off unnecessary lights, we can help to reduce light pollution and its negative impacts on the environment and our health. The 5 Principles for Responsible Outdoor Lighting provide a framework for reducing light pollution while creating a better quality of life for all living things. At NightVision Outdoor Lighting, we take light pollution seriously by designing our products with the goal of reducing light pollution from outdoor lighting. LEDs and compact fluorescents (CFLs) are great options for reducing energy use while protecting the environment; however, only warm-colored bulbs should be used.

Turning off all unnecessary lights is one of the most effective ways to reduce light pollution. Additionally, changing the color balance on devices to adapt to the time of day they're being used helps as well. Hanging light-blocking curtains or shades over windows also helps keep unwanted artificial lighting out of your home or office space. There are many other impressive ways that you can help reduce light pollution such as reducing decorative lighting use or using covered bulbs that direct their illumination downwards instead of up into the sky where it's wasted energy. LED lights are also a great option since they consume less power than traditional incandescent bulbs while providing more efficient illumination in both indoor and outdoor settings. Finally, keeping lights low to ground is important too; instead of using 25 foot poles in parking lots 10 foot tall poles will do just fine without wasting excess energy into night skies above us!
