Lighting Design Goals J Wunderlich PhD Example: Gallery Lighting with a mix of Natural & Artificial Lighting From Chapters 11 to 16, and 21 of the Illuminating Engineering Society (IES) Lighting handbook, 10th edition, 2011

1. Lighting is for the artwork more than for the observer 2. Use northern sunlight, including from north-facing skylights, to provide evenly distributed soft light, free of glare 3. Do not allow direct sunlight on artwork (to prevent damage) 4. Fill spaces with natural daylight as much as possible (without damaging artwork), then highlight artwork only as needed. This will provide high-quality light as well as energy efficiency, and will earn points for LEED (Leadership and Energy and Environmental Design) certification of the building 5. Control the magnitude and spectra of all optical radiation on artwork to prevent damage 6. Also be aware of the thermal effects of lighting on artwork 7. Identify each work of art as either “high”, “low“, or “no” sensitivity; Then control lighting accordingly 8. Use only “subtle” or “soft” accent lighting on artwork (i.e. not “moderate” or “strong”) 9. Use accent lighting that is not on artwork to provide way-finding and highlighting of architectural features in the gallery 10. Minimize Impact on gallery from adjacent high-illuminance spaces such as hallways, lobbies, and restrooms; if necessary, use a “Light Lock” (a vestibule; a separate transition space like in a theater) 11. Use low reflectance ceilings, walls, and floors in low-illuminance gallery; and low reflectance ceilings, walls, and floors in adjacent high-illuminance spaces 12. Use indirect lighting to enhance ambient light, and to provide way-finding and highlighting of architectural features; for example wall sconces, pendants, chandeliers, or up-lighting

Architectural Lighting Color Rendering Index (CRI) Quality of Light Source in how it makes an object’s color appear; Scale: 0 to 100

DAYLIGHT. High power at all wavelengths ("full color spectrum"); highest level of color rendering across the spectrum. CRI = 100

Halogen is often the best choice for Artwork - It adds a special “sparkle” (REF: https://www.youtube.com/watch?v=aVXoOuzGA0I )

LED’s are improving, but not yet replacing Halogen everywhere for lighting Artwork
