The height-adjustable frame of the in-ground housing allows a compensation of dimensional tolerances between plain ceiling and finished floor or in case of slanting floors. The shallow recess depth from 100mm makes the Nadir suitable for many applications in architecture. Even mounting in floating floor screed with sound insulation requirements is possible without a problem. The Nadir recessed floor luminaires can be mounted using a cover frame to cover the floor aperture or with flush floor, trim detail.

A junction box rated to protection mode IP67 is available for the efficient through-wiring of a row of luminaires.
