Sustainability

LED Lighting

Conservators are asked to provide clearly defined answers to complex preservation questions so often that they may actually start to believe that it is possible to give them. The Green Task Force (GTF), created by AIC to tie sustainability to our conservation profession, has repeatedly confronted this expectation. We find that areas of concern (e.g. environmental set-points) have commonly assumed “standards” based on empiricism, habit, and available technology, rather than adopting a more nuanced approach that might better meet the needs of our collections and institutions. 

Recent postings regarding the use of LED lights for display of museum collections prompted the GTF to dig deeper into the question of whether this developing technology is ready for us to implement and promote.  This presents a timely opportunity to educate ourselves on yet another complex and developing area impacting our profession. The lighting industry will address our requests for safe, efficient illumination with improved products but only if we are forthcoming with the details of what we require, and are willing to engage in an informed exchange. For this reason, a healthy, open discussion is important, and that isn’t possible without a solid understanding of the issues and the science.

We are most grateful to Steven Weintraub, who has pulled together information on this topic in a way that should be directly relevant to conservators.  It is our hope that this will put us on track to talk with industry experts as we work to solve our small scale preservation problems in concert with the world’s big environmental problems.
