ARCOS III: the fine art of light

Feb. 11, 2021
The zoom focus lens gives the luminaire the ability to flexibly distribute light and adapt the beam to the size of the artwork as a light cone with a soft focus or hard edge for objects.

Zumtobel's new spotlight ARCOS III is the third generation in the ARCOS family and offers a highly flexible lighting tool that can be used to create exciting new lighting solutions for museum curators and lighting designers. Developed for the constantly changing requirements of exhibition spaces and originally designed by David Chipperfield, ARCOS III brings artworks to life with new ways to stage art works and create exhibition designs with appealing scenography.

Using the new innovative and highly intuitive zoom focus lens, ARCOS III enables artworks to be individually lit and highlights their unique character and features. The zoom focus lens gives the ability for light distribution to be flexibly and precisely adapted to the size of the artwork as a light cone with a soft focus or hard edge for objects. The extremely precise light distribution ensures maximum uniformity and strong contrast enabling artworks to be illuminated with the maximum proportion of light without disruptive light scatter.

ARCOS III uses the Monza method which recommends warm-white and cool-white colour temperatures paired with flood and spotlight light distribution for exceptional illumination.

This can be achieved via the tunableWhite technology which combines high colour rendering with balanced light distribution to create different atmospheres, emphasise colours and materials and meet a wide range of requirements for art exhibitions, styles and objects. The combination of the tunableWhite technology with variable beam angles, make it possible to create unusual lighting concepts. Lighting scenes and settings can be easily adjusted via the app using Bluetooth basicDim Wireless, DALI or on-board directly on the luminaire.

The tunableWhite technology also offers reliable protection for sensitive materials, by illuminating artworks gently and only when required using the lowest Kelvin value warm-white and the lowest luminance possible. The amount of light required and collateral light scatter is reduced, with significant energy savings and a reduction in possible damage caused by optical radiation.

High colour rendering Ra > 96 for stable white and a low colour shift (MacAdam2) enable an exhibit to be seen in its best light.

A visit to a museum or gallery can be an unforgettable experience if the design, architecture and lighting are perfectly aligned, allowing the artworks be appreciated in their purest form, bringing out the unique character of works of art and providing the perfect visual experience.
