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

A critical, near-universal step is performing on-site visual testing. A "mock-up" is created, and staff test different fixtures to see how they affect the artwork's appearance.

) to prevent damage, particularly for sensitive items like textiles and watercolors (often kept below 50 lux).

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

The industry is moving toward a greater need for standardized, detailed spectral data from manufacturers, as traditional, blunt metrics like CIE-Ra are considered insufficient for the nuanced capabilities of modern LED technology. To tailor this review further,? LED technology updates since 2017? Specific artwork materials (e.g., oil paintings, textiles)?

Light sources are selected for minimal Ultra-Violet (UV) and Infrared (IR) output, often through LED technology.
