LED lights can cause light pollution, which has negative effects on human and animal health

LED lights are becoming increasingly popular due to their energy efficiency and cost-effectiveness. However, the adoption of LED lights has also led to a growing concern about their impact on light pollution, which can have negative effects on both human and animal health.

Light pollution refers to the excess artificial light that illuminates the night sky, obscuring the visibility of stars and disrupting natural light levels. The switch to LED streetlights in Chelan County, Washington, for example, resulted in an increase in light pollution, masking about half of the previously visible stars. This issue is not unique to Chelan County, as communities worldwide have been transitioning from traditional orange-tinged high-pressure sodium bulbs to whiter and brighter LED lights.

The blue light emitted by LED bulbs contributes significantly to light pollution. This type of light has been associated with "substantial biological impacts" across Europe, according to a study by academics at the University of Exeter. The increase in blue light radiation has reduced the visibility of stars and may impact people's connection to nature. Additionally, blue light can alter the behavioural patterns of animals, such as bats and moths, affecting their movements toward or away from light sources.

The impact of LED-induced light pollution on human health is also significant. Research suggests that artificial light at night can negatively affect human health, increasing the risks of obesity, depression, sleep disorders, and diabetes. Specifically, the American Medical Association has found that white LED lamps have five times the impact on circadian sleep rhythms compared to conventional street lamps. This disruption to circadian rhythms can lead to reduced sleep times, dissatisfaction with sleep quality, excessive sleepiness, and impaired daytime functioning.

While LED lights offer energy savings and modern lighting solutions, it is essential to address their potential contribution to light pollution. Mitigation strategies, such as choosing LED lights with warmer color hues and lower Kelvin temperatures, can help reduce the negative impacts on human and animal health while still enjoying the benefits of energy-efficient lighting.

Warmer-hued LED lights with lower Kelvin levels can reduce light pollution

LED lights have been marketed as an energy-saving solution, but they have also been associated with increased light pollution. The transition from traditional orange-hued bulbs to whiter and brighter LED lights has had unintended consequences, with reports of the night sky becoming significantly brighter in some areas. This issue was observed in Chelan County, Washington, where the shift to LED streetlights resulted in a notable increase in light pollution, obscuring the visibility of stars.

While LED lights offer energy efficiency, the type of LED and its colour temperature play a crucial role in determining its impact on light pollution. Warmer-hued LED lights with lower Kelvin levels are recommended to reduce light pollution. Doctors advise against using LED lights with high levels of blue light, which can negatively affect human health and disrupt natural ecosystems. Blue light suppresses melatonin production, affecting sleep and circadian rhythms. Additionally, blue light scatters more in the atmosphere, contributing to light pollution.

To address this issue, it is suggested to use LED lights with a colour temperature below 4000 Kelvin. Lights at 3000 Kelvin have about 21% blue light, while those at 4000 Kelvin contain approximately 29% blue light. LED lights with even lower colour temperatures, such as 2000 Kelvin, are also available. These warmer-hued lights are less likely to scatter in the atmosphere, reducing their impact on light pollution.

However, the transition to warmer-hued LED lights faces challenges due to manufacturing and market demands. Light manufacturers have been reluctant to adopt warmer hues, and there is currently insufficient demand for lights with extremely low Kelvin levels. Nonetheless, some places, like Flagstaff, Arizona, have successfully implemented the use of warm-coloured LEDs.

While LED puck lights are popular for their energy efficiency and versatility, the discussion about reducing light pollution through warmer-hued LEDs is relevant to a broader range of LED lighting applications. LED puck lights are commonly used in homes for task lighting, accent lighting, and enhancing specific areas. They are often installed in kitchens, cabinets, hallways, and reading nooks. By opting for dimmable LED puck lights, users can adjust the brightness to suit their needs and create a more ambient atmosphere, reducing the potential impact on light pollution.

Proper design and intentional placement of LED lights can minimise light pollution

LED lights are popular because they are energy-efficient, long-lasting, and cost-effective. However, they have also been linked to increased light pollution. Light pollution is a human-made alteration of outdoor light levels from those occurring naturally, and it has harmful effects on streetlights, greenhouses, satellites, wildlife habitats, and human health.

LED puck lights are a type of LED light that is small, round or oval, and easy to mount. They are often used in kitchens, cabinets, hallways, and workspaces to provide task lighting or accent lighting. While they are energy-efficient, there is no evidence to suggest that they help reduce light pollution.

However, proper design and intentional placement of LED lights can minimise light pollution. Agencies like the National Park Service and the American Medical Association have recommended ways to reduce light pollution and its harmful effects. For example, they suggest buying LED lights with warmer-coloured hues, such as yellow or amber, and avoiding blue light, which is known to reduce melatonin production in humans, leading to various health issues.

In addition to choosing the right type of LED light, it is important to be intentional about where the lighting is located. This means considering whether a light is needed in a particular spot and what the appropriate brightness is for that use. For outdoor lighting, it is recommended to avoid shooting light at angles above the horizon to the night sky and to use a glass or sunshade to reduce upward or backward light emission.

Furthermore, dimmers, motion sensors, and timers can help reduce average illumination levels and save energy. Proper design and intentional placement of LED lights can ensure that we benefit from their energy efficiency without contributing to light pollution and its negative consequences.
