Lighting Considerations

Artificial Lighting Guidance – Wildlife

Domus Projects strives to offer a high-quality design with a particular focus to the environment, when approaching projects of this type we analyse the following

Light Levels 

Correct lighting design should always at a minimum produce the recommended lighting levels of illuminance and uniformity. For projects with attention to the wildlife, we will ensure that light levels are kept to the recommended minimum whilst still being compliant to relevant standards.

Illumination Boundaries

We will always define the proposed area to be illuminated and focus our fittings so that light spill can be limited within these boundaries. We will also work with the environmental consultant on the project to define on the design Bat corridors, routes to feeding, water and breeding locations 

Colour Temperature & UV

Warm lighting at 2200-2700K from studies appears to be the most suitable solution for these types of projects. We would normally suggest fittings within the colour spectrum and avoid the harsher white light of 4000K.

UV Light has an adverse effect to the wildlife in particular in during the night hours for nocturnal creatures, it is recommended to reduce the amount of UV a luminaire will produce.

Optical Distribution / Cowls

The advantages of LED lighting is the wide variety of optics available. Nowadays we are able to specify fittings with downward only light distribution with cut-off’s to prevent unwanted light spill. 

In areas which need particular attention the use of cowls (shields) can be used to further prevent light spill and glare.  

Eurobats Guidance

The Eurobats guidelines on artificial lighting in regards to bats was published in 2018. It covers wide knowledge base of observations and solutions to reduce the negative impacts caused by artificial lighting.

Consideration should be given to the wildlife and environment before any lighting design is approached. 

Bats Conservation Trust

The Bat Conservation Trust BCT has made their Good Practice guidelines available to download as a non-printable pdf document. It is an essential guide for ecological consultants, working on bat related projects
