ARCOS - the spotlight system for sophisticated lighting scenarios
How do we present art in its most impressive form? ARCOS offers museums, galleries, and cultural institutions a precise lighting tool that effortlessly adapts to various ceiling heights and spatial conditions. The functions for zooming and focusing are as intuitive as those of a camera lens, which makes using the lighting particularly simple. Thanks to a special lens system, variable light distributions, adjustable beam edges and colour temperatures are possible. Stray light and multiple shadows are a thing of the past, allowing the focus to be entirely on what's important. ARCOS III Zoomfocus is the solution to the ever-evolving challenges of exhibition design – at the highest standard.

Maximum cost efficiency
Particularly energy-efficient
Perfect light staging
ARCOS - a unique, ultra-precise lighting tool offering a selection of lumen packages and optical lens solutions in two spotlight sizes - compact medium and large - ideally suited for varying ceiling heights from standard to high.
Thanks to Tunable White with variable colour temperatures from 2,700 to 6,500K, the ARCOS spots are universally applicable, whether for old masters or modern photography. The combination of Tunable White and Zoomfocus optics opens up new dimensions of perception and storytelling. Based on the Monza method, it is particularly suitable for large painting formats by enhancing the visual impact through varying colour temperatures and beam angles.
Precision and flexibility for museum masterpieces
The ARCOS product family revolutionises art presentation with its camera-lens-like zoom focus system featuring precise beam edges and no stray light. The special lens technology ensures superior colour rendering (Ra95), perfect uniformity, and optimal contrast for impressive presentations. In two sizes for ceiling heights up to 10m, ARCOS offers maximum adaptability for various exhibition concepts. The thermal separation of electronics and LED ensures durability, while intuitive control options via Bluetooth, DALI, or directly on the spotlight simplify operation.

Questions about the ARCOS luminaire
Which ARCOS product size is suitable for which ceiling height in the art & culture sector?
The choice of suitable ARCOS III Zoomfocus lighting depends on the ceiling height in museums and galleries. Size M is optimal for exhibition lighting up to 5 metres - it allows for precise light distribution. For ceiling heights up to 10 metres, we recommend size L for professional museum lighting. This thoughtful coordination can create a uniform artificial lighting atmosphere that stylishly showcases exhibits.
What is the colour rendering index (CRI) of ARCOS?
The quality of the LED spotlights is particularly evident in the colour rendering - a crucial criterion for demanding precision lighting. The innovative white light module achieves a CRI of at least 90, typically even 95, with an R9 value of 95. This high-quality lighting technology makes colour nuances shine with exceptional authenticity.
What beam angles can be achieved with the adjustable Zoomfocus?
The ARCOS III Zoomfocus lighting allows for variable beam angles between 7 and 37 degrees due to its beam shaping. This flexibility makes it the ideal accent lighting for museums. From precise spot lighting to harmonious surface illumination - Tunable White technology offers a wide range of design possibilities for your exhibition lighting.
Which accessories can be connected?
With optional accessories, the museum lighting can be tailored even more precisely to your requirements. The ARCOS III Zoomfocus lighting can be expanded with oval lenses or WFL lenses. While oval lenses create a directed, elongated light distribution, WFL lenses provide uniform illumination for larger areas.
What makes ARCOS lighting so special?
The precision lighting of the ARCOS system stands out with its unique properties. The uniform light pattern prevents disruptive shadows. The innovative lighting technology minimises stray light and precisely directs the accent lighting. The stepless zoom and focusing capability allows for flexible artificial lighting design.
Is the ARCOS lighting dimmable?
The avant-garde design of the ECOOS II luminaire was awarded the Red Dot Design Award, and indeed, the ARCOS III Zoomfocus lighting offers advanced lighting controls. The DALI system allows for precise brightness control via Bluetooth connection. Alternatively, a 1-10V potentiometer is available for adjustment. This flexibility makes the LED spotlights the ideal solution for professional exhibition lighting.
