Retail lighting design
Retail lighting design that sells the product
Retail lighting design puts the product first: high colour rendering on the merchandise, ambient light held deliberately lower so the accented displays carry the room, and a window that draws people in from the street. NR Lighting designs retail lighting for flagships, boutiques and multi-site roll-outs in London and across the UK, from concept to a technical pack the shopfitter can install from.

What does retail lighting design involve?
A retail scheme is built in layers. Ambient light sets the base level and the mood of the store; accent light from track spots or recessed adjustables picks out product with a contrast ratio of roughly three to five times the ambient level; vertical light on walls, gondola ends and joinery makes the space read larger and guides the customer through it; and the window and fascia do the job of stopping people on the pavement.
The design decides where each layer goes and what it should achieve before any product is chosen. Luminaires are then selected for beam angle, colour rendering, glare control and efficacy, checked against their photometric data, and proved in a Dialux Evo model so the lux levels, uniformity and installed load are known before the shopfit is priced.
Colour temperature and colour rendering for retail displays
All of NR Lighting’s retail projects to date have used 3000 K warm white: it flatters skin, wood and packaging and reads as premium without the yellow cast of 2700 K under high accent levels. What matters more than the number is colour rendering. A CRI of 90 or above, with good rendering of saturated reds (R9), is the difference between chocolate that looks glossy and chocolate that looks brown, between a fragrance bottle that sparkles and one that looks dull.
Product categories have their own needs: cosmetics and fragrance want crisp, high-CRI accents and lit testing islands; food and confectionery want warmth with strong red rendering; fashion needs vertical light on rails and a true rendering of colour in the fitting rooms; a tattoo studio needs high, shadow-free task illuminance at the chair with a moody ambient everywhere else.
Illuminance targets for retail
BS EN 12464-1 gives maintained illuminance for retail premises: 300 lx across the sales area, 500 lx at tills and wrapping desks, and higher values on the displays themselves. In practice, flagship schemes are designed to a higher accent level on the merchandise and a lower ambient than the standard alone would suggest, because it is the contrast that sells.
The projects on this page were designed to targets between 600 and 1,000 lx on displays at 3000 K, with installed loads of roughly 8 to 11 W/m², all with LED sources. Those are design targets from the calculations, not measured values on site.
| Area | Typical target | Notes |
|---|---|---|
| Sales floor ambient | 300 lx maintained | BS EN 12464-1; often designed lower in flagships with strong accent light |
| Tills and wrapping | 500 lx maintained | Task area with good vertical light for faces |
| Feature displays | 750–1,000 lx | Accent ratio of 3:1 to 5:1 against ambient |
| Window display | 1,000 lx and above | Daytime competition with daylight; dimmed after dark |
| Fitting rooms | 300–500 lx | CRI 90+, light on the face, not the ceiling |
Multi-site roll-outs and brand standards
For brands with more than one store, the value of a designer is consistency: a lighting standard that fixes the layers, colour temperature, CRI and lux ratios, a luminaire palette with equal-and-approved criteria, and a control strategy that behaves the same way in every unit. Each new site is then a layout and a calculation rather than a fresh design, and the shopfitter knows what to price.
Energy, Part L and controls in retail
High display levels and Part L pull in opposite directions. The scheme resolves that with efficient luminaires, accent light aimed where it earns its keep, and controls: daylight-linked dimming near the window, time schedules that drop the window and feature light after closing, and a maintenance factor that is stated rather than assumed. Where the efficacy route is tight, a LENI calculation to BS EN 15193 shows the real annual energy of the scheme with its controls.
Working with shopfitters, architects and brand teams
Retail programmes are fast. The technical pack is written for the shopfitter: reflected ceiling plans in DWG, a luminaire schedule with track, spot and driver data, a specification with equal-and-approved criteria, and a control narrative for the electrical contractor. On site I review samples, check substitutions and aim the accent light on the day the merchandising goes in.
Retail lighting projects
Hotel Chocolat’s Manchester flagship pairs track and spot lighting with warm perimeter uplighting and a central curved mesh ceiling with linear uplighters. Molton Brown on Regent Street uses precision track lighting and custom pendants to highlight the central testing islands, with warm integrated joinery lighting. Dan Gold’s tattoo studio on Oxford Street balances an edgy aesthetic with high-contrast, high-CRI track and spot lighting for colour accuracy at the chair. The project cards below carry each scheme’s design targets.

Frequently asked questions
What lux levels are recommended for retail?
BS EN 12464-1 recommends 300 lx maintained across a sales area and 500 lx at tills. Displays are lit to a higher accent level, typically 750 to 1,000 lx, so that the product stands out at a contrast of three to five times the ambient light. Windows are designed higher again to compete with daylight.
Which colour temperature and CRI should retail displays use?
Most premium retail works at 3000 K warm white with a colour rendering index of 90 or higher, including good red rendering (R9). Cooler 3500 to 4000 K suits some technology and sportswear brands. The choice depends on the product and the interior palette, and it should be fixed in the brand’s lighting standard.
Can you design a scheme for multi-site roll-outs?
Yes. A roll-out starts with a lighting standard that fixes the layers, colour temperature, CRI, lux ratios, luminaire palette and control behaviour. Each new store then becomes a layout and a Dialux calculation against that standard, which keeps the look consistent and the shopfitter’s pricing predictable.
How does lighting affect dwell time and conversion?
Light steers attention. Contrast between accented product and a quieter ambient level pulls the eye to the merchandise, vertical light makes the store feel larger and easier to read, and good colour rendering lets customers trust what they see. Those are the design levers; the scheme is then tuned to the brand’s own merchandising strategy.
Do you work with shopfitters and brand guidelines?
Yes. The technical pack is written for the shopfitter and electrical contractor, and the design works within the brand’s guidelines where they exist. Where a brand has no lighting standard, NR Lighting can write one so that future sites are consistent.
