The native wood of the maple is especially oiled to endow it with unique characteristics of high resilience, stability, and exceptional texture. A gradual darkening of the natural products over the years has provided ARBA with another attribute: the wood makes the refreshingly cool light of the energy-saving fluorescent lamp glisten and transforms it into a warm yet powerful and comfortable light while bestowing a unique atmosphere to the room. The diffusor used for vertical illumination is made of solid acrylic with highly polished edges to direct an even, glare-free light.
