Sustainable technology, compact size

1. Design & functions
 
ARCOS xpert perfectly combines design and functions. Like its conventional predecessor, the LED spotlight system blends harmoniously into a variety of environments. True to Zumtobel’s credo “tried-and-tested design, new technology”, the new generation’s appearance has remained unchanged, so that the LED version can easily be combined with conventional ARCOS lighting solutions. ARCOS xpert provides maximum flexibility – due to a variety of additional functions:
 
  • Spotlight can be locked into position
  • Spotlight is dimmable (at the luminaire or via DALI)
  • Rotating attachment holder and encoded lens
  • Cool touch function
  • Holder suitable for a large range of accessories
2. Optical system
 
A combination of specially shaped polycarbonate reflectors and selected lens optics that is perfectly matched to the LED module ensures excellent lighting quality: the ARCOS xpert LED spotlight cannot fail to impress thanks to its excellent glare control (no light source visible) and uniform high-precision light distribution. The high level of luminous intensity is focussed in the centre and softly decreases towards the edges – another characteristic feature of ARCOS xpert adding to its excellent lighting quality.
3. The LED light source
 
Due to its compact size, the innovative LED module is ideal for accent lighting. In addition, it boasts excellent colour rendering
(Ra 94 at light colour 930) and tight colour tolerances (2-step MacAdam). Moreover, the UV and IR-free light is gentle on the exhibits and prevents the colours from fading. As a result, the ARCOS xpert LED spotlight fascinates with superior lighting quality.
4. Passive cooling
 
The level of lighting quality achieved in an application depends on optimum thermal management. The high-power ARCOS xpert LED spotlight boasts an intelligent passive cooling system allowing for luminous flux and service life to remain at a constantly high level. In addition, due to the cooling system’s innovative design, no openings are required in the housing. Like its conventional predecessor, the LED spotlight’s converter box also features a cool touch function: thus, ARCOS xpert spotlights can be individually adjusted to changed situations at any time.

Sustainable technology, high light output

1. Design & functions

The only visible difference between ARCOS 3 xpert and ARCOS 2 xpert is the former's slightly larger diameter – ideal for combining both sizes in one room. That's not all: the consistently designed ARCOS product range with its various models and lumen packages is able to meet a variety of lighting tasks in museums and art galleries, while perfectly catering for various ceiling heights and lighting distances.
With illuminance levels of up to 2000 lm, ARCOS 3 provides perfect accent lighting from great heights.
This extremely high flexibility is based on multiple additional functions:
  
  • Spotlight can be locked into position
  • Spotlight is dimmable (at luminaire or via DALI)
  • Rotating attachment holder and encoded lens
  • Cool touch function
  • Holder suitable for a wide range of accessories
2. The optical system

In addition to louvre optics such as ring louvre or honeycomb mesh, a number of reflectors and special films are available for ARCOS xpert. By combining them, light control, glare limitation and lighting effects can be designed as required. The extremely uniform lighting cone is supplemented by beam angles ranging from 8° (superspot) to 40° (wideflood). Using oval or rectangular lenses, the shape of the lighting cones can be modified.
3. The LED light source

The innovative LED module ensures perfect accent lighting: at colour temperatures of both 3000 K and 4000 K, the spotlight achieves an excellent colour rendering of Ra 98 in all colour spectrums, combined with extra-tight colour tolerance of 1x2-step MacAdam. With an outstanding R9 level of 98, ARCOS LED spotlights meet the highest requirements placed on museum lighting.
4. Passive cooling
 
The higher the lumen package, the higher the requirements placed on thermal management. Despite its high output, the designers managed to provide the ARCOS xpert high-performance LED spotlight with an intelligent passive cooling system. Thus, the housing does not need any ventilation slots, although it is ensured that the spotlight achieves maximum luminous flux and has an extremely long service life. Similar to other sizes, the LED spotlight's converter box features a cool touch function: thus, ARCOS xpert 3 spotlights can be re-adjusted to changed situations at any time.

Compact expert for sharp outlines

Based on the qualities of the ARCOS 2 xpert spotlight, the equally compact projection spotlight sets the exhibits centre stage to optimum effect – with sharp outlines, uniform light distribution and at the same time low illumination of walls. High flexibility is provided thanks to mechanically adjustable lenses ensuring that the light emitted in parallel is given the required shape.
Thanks to the framing spotlights' lens system with adjustable focus, objects and pictures can be illuminated with sharp outlines.

The high-precision lighting tool for every lighting task

A major requirement for illumination of museums and exhibitions: perfect, glare-free light. For this purpose, ARCOS uses front rings, special reflectors as well as high-contrast covers and louvres. For the luminaire to be able to respond flexibly to changing lighting tasks, the optical units can be replaced without any tools.

The perfect coordination of LED module and optical system results in maximum precision, uniformity and intensity. ARCOS 2 LED xpert's extremely tight colour tolerance (2-step MacAdam) has again been reduced by half for ARCOS 3 LED xpert (1x2-step MacAdam). Size 2 achieves an excellent colour rendering index of Ra 94, which is, however, exceeded even further by size 3 (Ra 98).

Intelligent accessories for perfect presentations

A variety of accessories. Unbeatable flexibility
 
It is considered the most important lighting task in a museum or an exhibition to present an exhibit’s message or shape to optimum effect. In this respect, the effect is often determined by the finest nuances of a material or colour. Due to its large variety of accessories, the ARCOS range provides optimum prerequisites for finding a target- oriented solution to any challenge in just a few simple steps. The following accessories are available for perfect illumination: four lenses, four exchangeable reflectors, a wallwasher attachment, a film holder, two special filters, two anti-glare louvres and barn doors. All lenses can be replaced without any tools and combined in a rotating attachment holder. This wide range of accessories makes the ARCOS LED spotlight system the ideal tool for perfect presentation of exhibits: in terms of flexibility as well as when it comes to lighting quality. Encoding of the lenses makes sure that the accessories used will stay in their exact position even after a light source or reflector has been replaced.
