LED usage is now widespread, driven by energy-reduction mandates, reduced maintenance costs, and longevity.
While not routinely used by all, some professionals analyze the SPD to manage damage, specifically looking at the blue light peak in LEDs, ensuring it does not exceed the "rule of thirds" (blue peak < 3 times the broader peak > 500 nm). 2. LED Adoption and Technical Selection How is Museum Lighting Selected?
The "spirit of place" is considered in historic houses, where lighting is designed for atmosphere and immersion, rather than just object preservation. Key Takeaway for Future Selection LED usage is now widespread, driven by energy-reduction
Final decisions often result from a consensus among curators, conservators, and exhibition staff regarding how the art looks under the light. 4. Visitor Experience and Practical Considerations LED Adoption and Technical Selection The "spirit of
The ease of replacing bulbs (or lack thereof for fixed LEDs) and cost are significant factors in long-term maintenance planning.
Based on the insights from Tess Perrin, Jim Druzik and Naomi Miller (2014) and interviews with UK museum professionals published in 2017 , museum lighting selection is a balancing act between preservation, visitor experience, and practical constraints. It is primarily guided by limiting light-induced damage, which often involves using LEDs and manual, on-site visual testing.
Institutions often set a minimum general colour rendering index (CIE-Ra) of 80, 85, or 90 to ensure accurate representation.
