In short
Multi-optic recessed downlights such as Foss group several small, individually shielded LED optics in one housing, giving high output, very low glare and precise beams.

Multi-optic downlights have become a favourite of architects for workplaces, galleries and retail.
How they work
Instead of one large light source, a multi-optic fitting uses a row or grid of small LED modules, each with its own black anti-glare optic. The light source is hidden deep in each cell, so the fitting looks dark and calm from most angles.
Why specify them
- Very low glare: Foss is rated UGR <13
- High output from a small aperture
- Narrow, medium or wide beams: Foss offers 12°, 34° and 48°
- Adjustable versions tilt by 30° for accent and wall washing
