Museums have a hard line to walk, exhibiting items for public education and enjoyment while protecting those same collections from damage. Today’s museum also carry the additional weight of safeguarding the future of the environment – as well as their financial future – against the dangers of unnecessary energy consumption. What advancements have been made in preservation lighting technology to help accomplish these goals?

Light, including all three types: ultraviolet (UV), infrared, and visible light, causes permanent and irreversible damage to museum pieces. Cumulative and dependent on the intensity and duration of exposure, light affects chemical composition, physical structure, and, the appearance of a collection. There is no conservation treatment that can repair it. Light damage is forever.

Only complete darkness ensures conservation, since exposure to light in any form naturally breaks down items. However, keeping pieces locked away in the dark defeats the mission of the museum – sharing those works with the public. It is thus a museum’s dilemma to find a suitable solution that balances the best of both worlds, in addition to considering energy costs and the environmental impact of its lighting selection.  

In your search for preservation lighting, you will find that a great deal of lighting solutions involve UV (ultraviolet light), the most energetic and destructive form of light. These include natural light, fluorescents, HID, and tungsten halogen lighting. Fortunately, the effects of UV can be controlled with simple filters, offering a greater variety of lighting options. UV filters are hard plastic tubes or soft sleeves wrapped around bulbs/light sources, which filter and block up to 98 percent of UV light, preventing its damaging effects. NOTE: UV filters lose efficiency over time and must be replaced every eight-10 years.

Specific, detailed recommendations for preservation lighting levels based on your collection type can be found from various sources, including the Library of Congress, National Park Service, UNESCO, and more.
