Linear track lights with a length of 101 mm and a power of 6 W are installed in the tracks of the MAG VIBE system and are suitable for local and accent lighting.
A special feature of the series is the DARKLIGHT glow effect (“light from nowhere”), indispensable for hidden installation of light sources. LEDs in individual cells create a bright, narrowly directed light beam, which allows you to place light accents without drawing attention to the lamp.
The series includes luminaires with daylight (4000 K) and warm (3000 K) glow, as well as models with variable color temperature (2700–5700 K) and control via DALI and TUYA Zigbee, which can be used to create biodynamic lighting.
Minimalist lamps in black or white will easily fit into residential, office, and commercial spaces.
