Previous life cycle assessments of light sources, i.e., lamps and luminaires, have shown that the energy consumption during operation is the main cause for environmental impacts. However, the assessments do not consider the environmental impacts caused by the light from the light sources, since currently there is no method for quantifying it in such assessments. This may distort the actual environmental impacts and lead to favouring of wrong light source technologies from a total environmental perspective. Artificial lighting has been shown to affect the behaviour and health of human, fauna and flora and thus disturbing the ecosystems. A calculation method is developed in the research to evaluate the impacts of light and light pollution on the basis of the known environmental impact mechanisms. The calculation method is important in the life cycle assessment of light sources and all systems where artificial light is needed, achieving more reliable evaluation of environmental impacts.
