The Architecture of Light.

We engineer optical instruments that disappear into building fabric—leaving only pure, disciplined illumination, spatial depth, and sensory stillness.

SECTION 02 // PHILOSOPHYTHE INVISIBLE LUMINAIRE

“Light is the building material.
The luminaire is merely its instrument.”

Conventional lighting fixtures demand attention through decorative hardware, exposed diffusers, and distracting ceiling clutter. Phaos inverts this paradigm. We design for absolute visual quietness.

By engineering deep-cutoff shielding angles and free-form optical prisms, our fixtures guide photons exactly where spatial intent requires them—revealing material textures, defining volume, and maintaining human comfort without glare.

01 / LIGHT

Photometric Truth

Rigorous laboratory goniophotometry verifying beam cutoffs, lux gradients, and spectral fidelity.

02 / SPACE

Spatial Hierarchy

Illuminating vertical boundaries and focal planes to expand the human perception of volume.

03 / PERCEPTION

Darklight Comfort

Unified Glare Ratings below 10, eliminating eye adaptation strain across high-contrast environments.

OPTICAL DISCIPLINES

The Six Disciplines of Architectural Light.

Architectural lighting is not a singular commodity; it is a vocabulary of specialized geometric disciplines calibrated to building surfaces.

DARK-LIGHT ACCENT (NARROW)6° NARROW ACCENT
IES LM-63 // FWHM 6° // SPOT

Surgical focal hierarchy with ultra-deep visual comfort

Collimated precision optic producing a tight, surgical 6° accent footprint with an evenly distributed core and zero peripheral glare.

VERTICAL PLANE WALLWASHASYMMETRIC PRISM
ASYM 38°IES LM-63 // FWHM 38° // WALLWASH

Uniform luminance expanding perceived volume

Engineered through free-form refractive prisms to illuminate from the ceiling-to-wall intersection down to the finished floor with zero scallop artifacts.

UGR 7.2 DARKLIGHTView Instrument
OVAL FLOOD / GRAZE15° × 60° OVAL BEAM
15° × 60°IES LM-63 // FWHM 15° × 60° // OVAL BEAM

Directional elliptical light beam for corridors and linear spaces

Special free-form cylinder lenses produce an elongated oval light footprint that cleanly follows linear corridors and floors with no central hot-spot burnout.

CONTROLLED FLOOD22° CONTROLLED FLOOD
22°IES LM-63 // FWHM 22° // FLOOD

Medium-angle distribution balancing contrast and coverage

Evenly distributed 22° flood beam with soft, gradual boundary transition and uniform center luminance for medium-throw applications.

DIRECTIONAL SPOT15° PRECISION SPOT
15°IES LM-63 // FWHM 15° // SPOT

Focal emphasis and sculpted modeling for architectural features

Precision 15° beam providing concentrated contrast and clean, evenly lit circular footprints across target floors and display surfaces.

THE INSTRUMENT REVEAL

Effect Precedes Hardware.

We never design a luminaire to be looked at; we design it to deliver an optical effect and disappear. Only after the light field is proven do we reveal the precision engineering of the physical chassis.
