The linear luminaire is installed in thin magnetic tracks of MICROCOSM and, thanks to the narrow angle of radiation, creates local or directional illumination.

Powerful luminous flux provides clear light accents in the interior. A high color rendering index guarantees comfortable lighting and maximum distinction of color shades - the lamp is also suitable for lighting retail and exhibition spaces.

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