The GERA spotlight with a power of 20 W is installed on single-phase tracks. Thanks to models with a rotating body and four options for the angle of emission, both directional and local lighting with a high color rendering index (CRI>90) can be created in any interiors—from apartments to stores and museums. The fixture is equipped with an anti-glare HONEYCOMB grid that provides comfortable light.
Easy installation and simple movement along the track allow changing the lighting atmosphere at any time, which is especially convenient in stores or showrooms where the exhibition is frequently updated.
