Notch 4

Design reveals form and void defined by light and space.

Anidolic Optics

Transcend Convention

A linear LED recessed luminaire with unique hollow aperture design, Notch 4 adds subtle punctuation of the ceiling plane with very low brightness, color accuracy, high optical and energy performance.

Transparent, vertical Anidolic optical structures with linear light extraction elements deliver precisely controlled optical distributions for low glare and wide spacing, enabling inspired environments that are luminous and comfortable.

Trimless Dado End

Create a unique finish with a continuous line of light. Perfect for drywall ceilings with exposed vertical fasciae, Notch 4's optional trimless Dado endcap adds texture, depth and detail to the ceiling plane, extruding the hollow architecture to the edge of drywall soffit.


Design your own layout using the trim and corner options or choose from one of our pre-existing patterns for simpler specification.

A wide variety of trims and endcaps.

Notch trim and endcap options add subtle punctuation of the ceiling plane. Extruded aluminum trim designs provide an easy installation with precise fit and finish. Grid options are compatible with both USG® 102 mm Logix t-bar and Armstrong® 102 mm Techzone® components.

Continuous Rows. Standalone Fixtures.

Contractor friendly design ensures simple installation with easy fixture alignment features, lift and shift optics with quick connects, and a magnetic install of the upper reflector with no tools.
