Retail Lighting — A Ready Reckoner for Stores & Showrooms

A quick-reference guide for retail projects. Retail lighting sells — it is driven by contrast and colour, not flat brightness. The eye goes to the brightest, best-rendered object, so ratios matter more than absolute lux.

Recommended lighting by zone

Zone	Illuminance (lux)	CCT	CRI	Notes
General sales floor	300–750	3000–4000K*	≥90	*Match brand + merchandise; keep consistent.
Feature / hero product	3–5× ambient	as floor	≥90	Tight beams (15–24°); this is where the eye lands.
Display window	2000–4000	3000–4000K	≥90	Must beat daylight to pull footfall; adjustable.
Premium / boutique	150–300 amb.	2700–3000K	≥90	Low ambient + strong accent = drama & luxury.
Fitting room	300 (vertical)	3000–3500K	≥90	Flattering light on the face — a conversion tool. Never overhead-only.
Cosmetics / beauty	500+ (vertical)	3500–4000K	≥95	True skin tones; light the face.
Jewellery / watches	high, tight	3500–4000K	≥90	Sparkle & crisp render; narrow beams, low glare.
Food / grocery	500–750	per product	≥90	Bakery warm; produce crisp; meat red-enhancing; UV-free.
Cash / POS (task)	500	as floor	≥90	Clear task light; a natural bright pause point.
Circulation / aisles	200–300	as floor	≥90	Lower than displays to preserve contrast.

Ten rules for retail light

• Contrast sells — feature products at 3–5× the ambient. If everything is equally bright, nothing sells.

• CRI ≥90 is the floor; ≥95 for premium, food and cosmetics.

• Match — and hold — colour temperature to the brand and product, consistently.

• Light the product vertically, not the aisle — that is what customers see.

• Win the window — it competes with daylight and the street; bright, adjustable, re-set often.

• The fitting room is a sales tool — flattering vertical light drives conversion and cuts returns.

• Stay flexible — adjustable track and aimable spots let staff re-merchandise weekly.

• Kill veiling glare on glossy packaging and glass — angle and shield.

• Protect the goods — UV-free, low-heat LED for fabrics, art and food.

• Mind energy & heat across long trading hours.
