IN-039 lighting design guide
IN-039 · LED
Deep clean lines for an illuminated statement ceiling.
IN-039 combines a disciplined outline with deeper modelling, giving indirect LED light enough room to create a dramatic but controlled ceiling wash.
Design and lighting guide
Designing concealed LED light with IN-039
The profile, source position and reflecting surface must be planned together. That coordination is what turns a hidden linear source into an architectural ceiling effect.
Let the profile geometry lead
The depth produces a strong shadow line below the illuminated plane. Keeping the light source concealed protects the clean profile and makes the glow appear to come from the architecture itself.
Treat the strip, channel and diffuser as one system; confirm their setback and aiming with the selected components. The principle is related to architectural light coves, adapted here to the beams of a coffered or waffle ceiling.
Match the effect to the room
It is intended for high ceilings, great rooms and statement interiors where the grid is viewed from across the space.
Control the ambient layer separately from recessed spotlights or decorative fixtures so the room can shift from everyday use to a quieter evening scene.
Plan the concealed components
Review viewing distance, ceiling reflectance and output together. A sample section can confirm that the wash reaches far enough without creating a bright band at the beam edge.
Also establish wiring routes, driver location and access, heat management and dimming compatibility before the beam details are closed and finished.
