Using Outdoor Lighting to Protect Local Wildlife and Environment

Outdoor Lighting to Protect Local Wildlife and Environment

Outdoor lighting is not just valuable for landscaping companies. It has also brought a multitude of advantages to today’s consumers. However, we wonder if these outdoor lighting fixtures adversely affect the nearby wildlife and our environment? A large number of studies reveal that using outdoor lighting often disrupts the natural flow of wildlife. For instance, sea turtles get affected by bright lights of condos and insects circle bright outdoor lights.

 

People who work at the International Dark-Sky Association believe that our ecosystem is getting affected by the continual usage of extra lights, which could pose serious risks for wildlife to function properly at night. It is a well-known fact that predators utilize light to hunt, whereas prey species take cover in the darkness. According to scientists, cloudy skies near cities and towns are now thousands of times brighter than they were a couple of centuries back, which is making a drastic impact on nocturnal ecology and wildlife.

 

Artificial lights create a glare that has the potential to disturb the night time mating rituals of several kinds of amphibians, which would ultimately contribute a major role in the decline of many species. Birds frequently go astray at night if they are incapable of differentiating between moon light and outdoor night. This risk is particularly significant for birds that hunt at night as the light affects their night vision.

 

Although there is a lot of negative information on outdoor lighting, you can still install it by keeping all crucial ecological facts in mind. You should implement outdoor lighting projects by taking the local wildlife, weather, and location into consideration. You must implement all projects after making them as eco-friendly as possible. Cover all important aspects of installing outdoor lighting without affecting the natural flow of wildlife. A major concern is choosing the right kind of light for your outdoor lighting projects.

 

Many of us are aware of incandescent or compact fluorescent bulbs for indoor lighting. However, outdoor lighting requires different or more industrial light sources. Although the light quality of incandescent is liked by shop owners and designers, the amount of electricity needed to run them makes them a less preferred option. Moreover, the fact that 90% of the energy they burn gets wasted leaves an enormous impact on the environment.

 

Hence, the most popularly used light sources for preserving wildlife comprise of LPS or low-pressure sodium, HPS or high-pressure sodium, metal halide and LEDs (light emitting diodes). LPS is extremely energy efficient. However, it emits just a narrow spectrum of pumpkin-colored light. Nonetheless, it continues to be one of the most preferred choices for lighting in environmentally sensitive areas as well as astronomical observatories.

 

Several cities use HPS for street lighting. Even though it produces an orange-colored light, the coloring is closer to ‘natural light' than that of LPS. If people prefer to use white light in an area, then LED's and metal halide are the most preferred choices. LED lighting is a good option for outdoor lighting since you can dim it according to your requirements. You can easily turn off them off or reduce the intensity to match the needs of an occasion. This way we can not only save energy but reduce the amount of light pollution emitted during the night.

 

With the launch of LED fixtures and LED bulbs, more ways to help our environment and wildlife have now emerged. If we know how to use this kind of lighting properly, we can overcome many negative effects that have been damaging our natural flow. Once people have decided the kind of outdoor lighting they like to work with, complement the bulbs with the right kind of fixtures. Although there are hundreds of different kinds of fixtures available to serve different needs, only a few are beneficial for protecting wildlife and the surrounding environment.

 

Moreover, light color also matters. In addition to having the right kind of lighting and fixtures, it is important that you can choose the right color of light. Sufficient amounts of blue light are present in both metal halide lights and LEDs. Since blue light brightens the night sky more than other types of lights, it is important to restrict the percentage of blue light the bulb emits into the surroundings. Research has established a definite relation between blue light exposure and harmful effects on human health and wildlife. Hence, according to IDA recommendations, it is beneficial to use a light that has a color temperature of fewer than 3,000 Kelvins.

 

Final Thoughts

It is important to discuss all possible options for environmentally safe outdoor lighting options, such as dimmers and eco-friendly lighting fixtures. To protect our wildlife and environment, we must use different levels of lighting for all outdoor lighting projects. For instance, we can go for soft mood or low lights for path lighting.
