Adapting the spectral composition of artificial lighting to safeguard the environment

Over 60 million birds, of many species, cross the North Sea each year, twice. Light has a significant impact on migratory birds at sea, as it can attract and trap birds at large illuminated structures, such as off shore platforms. We first studied the behaviour of birds around offshore platforms and secondly tested the effect of the presence of lighting, the intensity and type of lights and the light colour on bird behaviour. As a conclusion, about 10% of the North Sea migrating bird populations are impacted by offshore installations. We developed a light spectrum that can be applied off shore, offering safety to both humans and birds. A field demonstration test, involving the exchange of lights to the new colour on a gas production platform has demonstrated a reduction of bird reaction of at least 50 to 90%. Finally, the compliance to explosion safety requirements has been demonstrated. It is expected that the bird-friendly lighting will become the new standard for any installation situated in areas with bird migration.
