Lights with lower colour temperatures (typically below 3000K) are better for wildlife because they have less impact on the natural behaviours and activities of nocturnal animals. Nocturnal animals such as birds, bats, and insects rely on natural light cues to navigate and carry out essential functions such as feeding, breeding, and migration. Artificial light sources with higher colour temperatures (typically above 4000K) can interfere with these natural cues, disrupting the animals' circadian rhythms and affecting their behaviour. For example, high-colour-temperature lights can attract insects, which in turn attract predators that feed on them, leading to changes in insect populations and affecting the ecosystem. Additionally, high-colour-temperature lights can cause birds to become disoriented during migration, leading to collisions with buildings and other structures. Lights with lower colour temperatures are less disruptive to wildlife because they produce light that is closer in colour to natural moonlight and starlight. This can help minimize the impact of artificial light on nocturnal animals and allow them to carry out their natural behaviours without interference. With most of Vizona’s range of LED Lights we have the capacity to choose a colour temperature to suit the environs into which it is being installed. If the project is at an environmentally sensitive location where it could impact wildlife behaviours speak to the lighting team who can advise you on the best options.

What is dark sky ordinance?

A Dark Sky Ordinance is a regulation that is designed to reduce light pollution by controlling outdoor lighting. It is an effort to preserve the natural darkness of the night sky by reducing the amount of artificial light that is emitted into the atmosphere. Dark Sky Ordinances typically require that outdoor lighting fixtures meet certain standards, such as being fully shielded or directing light only where it is needed, in order to minimize light pollution. The purpose of a Dark Sky Ordinance is to protect the environment, wildlife, and human health from the negative impacts of light pollution, such as disrupting natural behaviours of animals, harming ecosystems, and negatively affecting human sleep and health. Additionally, dark sky ordinances promote energy conservation and can reduce light pollution, which can save energy and money for property owners and municipalities. Speak to the Vizona Lighting team for professional advice on the best luminaire options that minimise light pollution and comply with the dark sky ordinance. Vizona has a big range of Solar and Hardwired LED lights that only shed light downward and comply with the dark sky ordinance.
