As an essential component for the enjoyment of your object or collection, light can be both a blessing and a curse. Light is essential because it allows you  to fully experience and enjoy your collection or object, however it also has irreversible effects on some objects. The two aspects of light to control are the intensity and the duration of exposure. Although there are many components to the light spectrum, it is the intensity of light, or ultraviolet radiation (UV), which has the most damaging effect on light-sensitive items, and is the primary cause of most light-related damage.

By its very nature, light damage is cumulative and cannot be reversed. This means that once a painting, textile or work of art on paper has faded, the damage cannot be reversed. The risk of damage cannot be completely reduced unless all light is eliminated, however the risk can be reduced. We can work with you to develop strategies aimed at reducing the effects of light on your object or collection, by undertaking a monitoring program aimed at understanding the light vulnerabilities within the space.

Please contact us to discuss how we can help you develop and implement light reduction strategies for your collection.
