The GERA 20W spotlight is mounted on single-phase tracks. The compact cylindrical aluminum housing can be rotated, directing the light where it is needed. Thanks to models with four beam angle options, it is possible to create both directional and local lighting with a high color rendering index (CRI>90) in any interiors - from apartments to shops and museums.
The ease of installation and the ability to move the lamp along the track allow you to change the lighting atmosphere at any time, which is especially convenient in stores or showrooms where the exposition is frequently updated.
Accessories are purchased separately.
