Layers
General 300 lx; accent 500-1000 lx on the goods; window lighting at night; backlight for the cash zone and the entrance.
Color rendering
CRI ≥ 90 for goods (textiles, cosmetics); 3000-4000 K depending on the assortment. The goods should not «turn blue».
Energy
LPD ≤ 15 W/m² per standards; LED with sensors and scenes. The audit checks the LPD.
Windows
Window lighting — separate circuits with timers: day/night modes. Accent spots at 30-40° on the mannequins.
Zones
Cash — bright even light; fitting rooms — warm 3000 K with mirrors; warehouse — 200 lx, simple fixtures.
Why design
The light sells: with the right design the turnover grows, and the audit is passed. GorkyCAD counts the fixtures and the LPD.
