The mistake of judging light by the floor
“You walk into a room and decide it's dark because the floor isn't shining? That's the biggest trap homeowners fall into!”
The problem
Judging lighting quality by direct brightness on the floor, which pushes the client to add more spotlights and strains the eyes.
Technical explanation
Professional lighting focuses on the walls (Wall washing) and vertical surfaces, because the human eye reads the brightness of a space from the walls, not the floor.
The result
Excellent visual comfort and zero “light noise”, just like luxury airport lounges and museums.
