“We wanted to create a product together that would not only be installed by museum directors for high-quality exhibition spaces but by ourselves as well.”
ARCOS LED Xpert | 22 W | superspot
ARCOS LED wallwasher, linear | 30 W | 620 mm long
2 LED xpert projection spotlight
1 | Front ring with condenser lens
2 | Adjustable iris diaphragm
(alternatively: framing cover)
3 | Adjustable focussing lens
Thanks to the framing spotlights' lens system with adjustable focus, objects and pictures can be illuminated with 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.

A major requirement for illumination in 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 Xicato Artist and optical system results in maximum precision, uniformity and intensity. The colour tolerance is exceptionally low and has been defined on the MacAdam ellipse as 1 x 2-step. What is more, the colour rendering of Ra 98 is almost unbeatable. An R9-value of 98 meets the highest requirements placed on museum lighting. The identical colour spectrum means that ARCOS LED 2 and 3 can be perfectly combined with each other.
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.
