Useful Light on the Surface
Move light beyond the cove so curtains, walls and displays remain illuminated farther down the vertical plane.
Stop Lighting the Ceiling.
Start Lighting the Space.
Many curtain coves and vertical surfaces look bright near the ceiling but become dark lower down. Artdon Lumi uses compact linear profiles and controlled optics to send useful light onto the surface, helping project teams improve vertical illumination without making the ceiling the brightest part of the room.
What Project Teams Need to Solve
The Right Beam for the Task
Use 45° for controlled close-range reach and 69° when the project needs a wider vertical distribution.
Minimal Architectural Detail
Use compact Lumi profiles, including 10mm-width options, when the curtain box, shelf or display detail leaves very limited space.
Reliable Visual Quality
CRI 90 and 2700K–4000K options support residential, retail, museum and display applications.
Correction After Installation
Use fixed, adjustable or magnetic mounting accessories to adapt the beam direction and installation method to real site conditions.
Lighting by Application
Curtain Coves
Direct controlled light farther down the fabric so the full-height curtain remains visible, not only the upper folds.

Feature Walls
Choose 45° or 69° according to installation distance, wall texture and the uniformity required by the project.

Optical Selection
Choose 45° for controlled close-range reach or 69° when the project needs a wider vertical distribution.
IES / LDT Support
Photometric files help designers check beam direction, coverage and expected surface illumination before specification.
Installation Distance Review
Share the cove size, distance to curtain or wall, target height and desired effect before final product selection.
Sample & Testing
Use samples and mock-ups to confirm the visual effect on the actual material and surface.
Mounting Accessories
Fixed clips, adjustable spring clips and magnets help project teams adapt Lumi installation to real site conditions.
