The slim body of the freestanding Linetik LED luminaire has a cross-section of 24 x 24mm and a compact base. The optical system delivers light where it is needed without glare. The reflector for the direct light output delivers uniform illumination over the workplace. An extrusion lens handles the indirect output, spreading light over a wide ceiling area. Direct and indirect lighting elements can be individually controlled, and a motion sensor turns the luminaire off when workers are absent.
