Turning off cities at night is not a viable solution. Lighting is essential for the safety and well-being of people as they move about for work or leisure. Cities that ensure clear visibility on their streets and roads increase the sense of security for both residents and visitors and tend to have higher economic performance and lower crime rates. Clearly we need to create safe spaces to sustain human activity at night, but it is also critical to preserve the surrounding natural environment. Getting the balance right is possible with the right lighting expertise and solutions. Urban lighting: a matter of balance

The impact of poor lighting Poor or inappropriate lighting can have serious consequences, increasing the risk of danger and actively disrupting the natural rhythms of all life forms, while wasting huge amounts of energy. For example, excessive exposure to blue light can be harmful as it suppresses the production of melatonin, a hormone that helps to regulate circadian rhythms. It can also affect the behaviour of animals, such as bats and moths, by altering how they move towards or away from light sources.

What is light pollution and how can it be avoided?

Lighting can potentially be harmful. However, this does not mean that we should avoid it, given its many benefits. With the right expertise and solutions, lighting parameters can be adjusted dynamically and precisely to preserve ecosystems.

Light intensity Can be adjusted based on the time of night or human presence.

Light distribution Well-designed lighting studies and photometry ensure that light is precisely where it is needed, with no light spilling backwards or upwards.

Colour temperature An appropriate or adaptive light colour temperature minimises blue light.

Your partner for the perfect lighting solution We have been supporting our customers with advice and expertise for more than a century. Our approach prioritises technical precision and reliability. By conducting site audits and comprehensive lighting studies, we ensure that each installation meets the unique requirements of each project and provides long-term, sustainable lighting.

Schréder has over 70 years of experience and expertise in photometry. Thanks to our thorough lighting studies and carefully designed range of optics and accessories, light is directed only where it is wanted and needed.

Light trespass behind the luminaire and upward light spill are key concerns when protecting sensitive wildlife habitats and restoring dark, starry skies. Our fully integrated solutions easily mitigate this potential risk.

These efforts, guided by the Dark Sky Association, help to create urban environments that are environmentally friendly and support biodiversity.

Perfect timing

A smart control system allows lighting to be planned and automated according to the needs and conditions of different environments.

Schréder EXEDRA seamlessly integrates with your network to provide valuable data insights and automate essential tasks. • It works with sensors to reduce lighting levels in unoccupied areas. • It can adjust lighting levels seasonally to minimise disturbance to sensitive species during certain periods. • Schréder EXEDRA LightSync enables adaptive lighting, which effortlessly adjusts the lighting level based on real-time data, saving energy while ensuring user safety and sustainability.

Perfect shade

A colder white light optimises performance, whereas a warmer light is more favourable to the natural cycles of people and animals. With the right technology, it is now possible to combine the two to create an efficient, eco-friendly light. Schréder recommends high-performance warm white LEDs with minimal blue light, combined with the Schréder EXEDRA control system and sensors. This enables the lighting to adapt permanently to the real-time needs, minimising disturbance to fauna and flora. Our range of specialised and static shades provides a lighting solution that is specifically designed to protect biodiversity. It does this by drastically reducing blue light while delivering good performance and colour rendering.

The FlexiWhite solution provides adaptable light colour temperatures that respect the circadian rhythm. It delivers the right level of light and right colour temperature in the right place at the right time. How does it work?

• A range of colour

temperatures from 1700K to 3000K • The colour temperature is programmed to change smoothly at various light levels • The light distribution remains precise and does not change, whatever the colour temperature.

Perfect compliance

Schréder monitors existing and future environmental requirements to ensure your lighting solution always complies. We believe that well-designed LED lighting can preserve the environment in many ways. That’s why Schréder has joined the Dark Sky International certification programme, the recognised authority on light pollution. It provides leadership, tools and resources to industries and businesses that wish to reduce light pollution. A luminaire is certified as DarkSky when it minimises or eliminates (depending on the options selected) the upward- directed light flux. It complies with strict international and local requirements.

DarkSky International criteria:

• Restricted emissions of blue light with CCT (correlated colour temperature) less than 3000K • Limited ULOR of a maximum of 0.5% (percentage of light emitted towards the sky) • Low glare for the best night-time experience • A safety certification from an independent laboratory

A responsible approach to urban lighting Schréder has developed a comprehensive approach to providing full-scope solutions, from design to after-sales services, with state-of-the- art lighting systems that preserve ecosystems. Our simulation tools provide precise information on efficiency, compliance, installation, energy savings and total cost of ownership.

At Schréder, we focus on the circularity and eco-design of our solutions to reduce our environmental impact by optimising each material flow. Our circular approach means that products are designed and built as part of a value stream, enabling them to be used for as long as possible. Depending on their characteristics, they can then be reused, refurbished, upgraded or recycled. Our Circle Light label evaluates all aspects of our luminaires, including

efficiency, ease of maintenance, disassembly and recyclability.

Reine Astrid square, Visé

The street lights are fitted with Schréder FlexiWhite technology, which adjusts the colour of the light for different seasons or events. This reduces energy consumption, light pollution and CO₂ emissions while promoting a vibrant and sustainable urban environment.

We have probably got one of the best spots in the Southern hemisphere for so many mammals. But we’re also very, very conscious of respecting and looking after that environment . Will Doughty CEO – Kaikoura District Council

Kaikoura A renowned dark sky community Kaikoura is a picturesque coastal town on New Zealand’s South Island, renowned for its stunning scenery and marine life. The local authorities are committed to preserving this natural ecosystem, especially the endangered Hutton’s Shearwater, which is now only found in Kaikoura. Luminaires fitted with very warm white or warm white LEDs and controlled by Schréder EXEDRA ensure that the natural night sky is preserved. Particular care has been taken along the coastline, especially near the habitats and flight paths of the endangered Hutton’s shearwater. Thanks to this smart lighting upgrade, Kaikoura hopes to become a DarkSky Community.
