Recessed floor luminaires emit their beam upwards. They are offered with narrow-beamed, wide-beamed, symmetrical or asymmetrical light distribution.

Criteria for recessed floor luminaires:
- choice of lamp determines light colour, service life, efficiency and light intensity
- uniformity: optimised reflector for even illumination of areas
- range of tilt for directional luminaires with high glare protection
- light output ratio is increased by optimised reflector technology
