The use of LEDs in cities is causing light pollution, which is making it harder for us to see and creating shadows. Lighting designer Simon Thorp notes that modern CCTV cameras can function well at low-light levels, but harsh light makes it difficult for both human eyes and digital sensors to see.
Imagine you're walking through a city at night, and the streets are so bright that you can't see anything. That's what's happening with light pollution, where too much artificial light is making it hard for us to see. It's like trying to see in a bright spotlight, but it's not helping us at all.

The Problem with LEDs in Cities
The use of LEDs in cities has been a well-intentioned effort to improve lighting levels and make our streets safer. However, the reality is that excessive lighting is causing more harm than good. The harsh glare from unshielded LEDs is creating shadows, impeding our vision, and giving us a false sense of safety.
Lighting designer Simon Thorp notes that modern CCTV cameras can function well at low-light levels, but harsh light makes it difficult for both human eyes and digital sensors to see. This is a critical issue because it affects our ability to see and navigate through cities at night.
The Impact of Light Pollution
Light pollution is a significant problem because it affects not only our ability to see but also our overall quality of life. Excessive lighting can lead to a range of issues, including sleep deprivation, stress, and decreased property values.
In addition, light pollution can also have a negative impact on the environment. Artificial lighting can disrupt the natural behavior of nocturnal animals, such as birds and insects, and can also contribute to climate change by increasing energy consumption.
A Better Approach to Lighting
So, what can we do to address the issue of light pollution? The first step is to recognize that excessive lighting is not the solution to our safety concerns. Instead, we need to focus on designing lighting systems that are more efficient, effective, and sustainable.
One approach is to use shielded lighting fixtures that direct light downwards, reducing glare and minimizing light pollution. Another approach is to use smart lighting systems that can adjust lighting levels based on the time of day and the level of ambient light.
By taking a more thoughtful and sustainable approach to lighting, we can reduce light pollution, improve our quality of life, and create a more livable and sustainable urban environment.
Key points
- Excessive lighting is causing light pollution, which is making it harder for us to see and creating shadows.
- Modern CCTV cameras can function well at low-light levels, but harsh light makes it difficult for both human eyes and digital sensors to see.
- Light pollution is a significant problem because it affects our ability to see and navigate through cities at night.
- Excessive lighting can lead to a range of issues, including sleep deprivation, stress, and decreased property values.
- Artificial lighting can disrupt the natural behavior of nocturnal animals and contribute to climate change by increasing energy consumption.
If we take a more thoughtful and sustainable approach to lighting, we can reduce light pollution, improve our quality of life, and create a more livable and sustainable urban environment. This could involve using shielded lighting fixtures, smart lighting systems, and designing lighting systems that are more efficient and effective.
If we continue to use excessive lighting, we risk creating a range of negative impacts, including sleep deprivation, stress, decreased property values, and environmental damage. We also risk perpetuating a false sense of safety, which can be misleading and lead to further problems.
