The adjustable spring-balanced arm of this desktop luminaire allows the shade to remain horizontal to the work surface, thereby providing an asymmetric light distribution free of glare and shadows. The wedge-shaped shade atop the 27-inch-long tubular steel arm houses a 35W halogen lamp. Available with a weighted base or a mounting clamp, Air also comes with an arm length of 32 inches and is offered in matte black and gray aluminum finishes.
