The ZEUS luminaire with a high colour rendering index (CRI>90) and a power of 20 W is installed on a single-phase LGD track.
The aluminum body effectively dissipates heat, increasing the service life of the lamp, and rotates easily. This allows you to change the direction of light as needed. It is also possible to adjust the width of the light beam - narrow for light accents and medium for local and main lighting.
This lamp will create cozy, flexible and comfortable lighting in any interior - from apartments to shops and museums.
