A linear luminaire with a length of 300 mm and a power of 8 W is installed in thin magnetic tracks of MICROCOSM and, thanks to the wide angle of radiation, is used to create general lighting.

The compact housing is made of high-quality aluminum and is easy to install, while the lamp protrudes above the track line. The matte screen provides an intense, but soft and comfortable glow without flickering. High-quality color rendering allows the lamp to be used, including in retail and exhibition halls.

The brightness of the lamp can be controlled using a PWM dimmer (PWN).
