Cafe Lighting Design: The Window, the Counter and the Clock

Most cafe lighting design is done for one moment: the evening the photographer comes. Then it opens at seven the next morning, when the shopfront outshines everything, the back of the plan reads as a cave and the menu is hard to read against the street. By six in the evening the downlights that looked crisp at noon make the room feel like a waiting room, and the glass that sold the place by day is a black mirror.

One room has to work at three times of day, with daylight doing most of the work in the first and none of it in the last. This guide sets out how to plan for the window, the counter and the clock: the layers, what to specify, the rules an architect in England should check, and what to agree before the ceiling closes.

Cafe Lighting Design Starts at the Window

Daylight is a cafe's best light and its biggest problem. A cafe is a workplace for its staff, and in Great Britain the Workplace (Health, Safety and Welfare) Regulations 1992 require every workplace to have suitable and sufficient lighting, which shall, so far as is reasonably practicable, be by natural light.

The difficulty is contrast. The Health and Safety Executive's Lighting at work (HSG38) says glare occurs "when one part of the visual field is much brighter than the average brightness to which the visual system is adapted." In a deep cafe with a full-height shopfront, eyes adapt to the street and everything past the counter looks dim. HSE notes that blinds or tinted glass reduce window glare, with the disadvantage that "they reduce the amount of daylight in the interior."

Archlior's view is that by day the electric light belongs at the back of the room. Wash the rear wall so the deepest surface in the plan is the brightest, drawing the eye through the room. From the pavement, a lit back wall is also what says the cafe is open.

After dark the problem reverses: glazing becomes a mirror at night, and a grid of downlights near the shopfront doubles itself in the glass. Keep ceiling fittings back from the glass and give the window bench its own low, shaded light, so the reflection is of a warm table rather than a ceiling. By day the same bench needs a blind for low sun.

The Layers of a Cafe

Ambient: light the walls, not the floor

In our experience a grid of downlights is the most common cafe ceiling and the least successful: it lights tables and floor, leaves the walls dim and makes a small room feel smaller. The workplace lighting standard looks at the room too: Fagerhult, a lighting manufacturer, notes in its summary of EN 12464-1 that the standard sets illuminances for walls and ceilings as well as for the task. In the UK it is published as BS EN 12464-1:2021, which BSI lists as current.

Wash the back wall and one long wall. Our guide to recessed lighting spacing puts wall washing fittings typically 30 to 45 cm out from the wall, with tighter spacing to avoid a scalloped pattern. A concealed cove can light the ceiling instead; test the sightline from the lowest and furthest likely viewing position, which in many cafes is the window bench.

The counter: a stage and a workplace

The counter should be the brightest horizontal surface front of house in every scene: it is where attention goes and where staff need to see detail.

Our guide to kitchen island pendant heights gives about 75 to 90 cm from worktop to the bottom of the pendant, from manufacturer guidance rather than any standard. In a cafe the coffee machine and the barista's line of sight to the customer decide the final height. The back bench needs concealed task light under shelves or in a joinery slot. Archlior's position on LED strip applies: CRI 90 minimum, 24V as the default, and driver placement matters.

The order point: light the face

In England, Approved Document M, Volume 2 warns that "light sources or reflective wall surfaces, such as glazed screens, located behind the reception point, could compromise the ability of a person with a hearing impairment to lip read or follow sign language." The paragraph before it refers to a "reception or sales counter", and Archlior applies the same caution to a cafe's order point, where a backlit menu, a glossy splashback or a window behind the barista can put the face in silhouette.

Light the person serving from the customer side, with a downlight or pendant just in front of the counter edge, and light menu boards from the front with an even, concealed wash.

Tables: pools for people who stay

Cafes have customers restaurants rarely have: people who stay two hours with a laptop. HSG38 notes that, at screen workstations, problems may arise "if light sources are badly positioned, causing screen reflections or glare." A customer is not an employee, but the optics are the same: use deep-recessed, low-luminance downlights or low pendants whose shades hide the lamp.

In the evening, overhead light alone shadows eyes and chins, so add wall lights over banquettes and apply the rule our guide to wall light heights gives for a sofa: a fitting should sit high enough that nobody sitting below has the lamp beside their ear.

Display and decorative

Our bakery lighting guide covers pastry displays and display refrigerators in detail. The colour rule is the one Archlior applies to retail and food: high Rg with low Rf makes colours look more vivid than they are. Our guide to CRI and TM-30 explains what to ask for: keep Ra in the specification, add R9, and request the TM-30 report.

Then choose one or two decorative pieces visible from the street: on a winter afternoon they say "open" better than any sign.

Colour Temperature: One Warm White

Our colour temperature guide is blunt: "Avoid 4,000K in food and beverage settings." Archlior recommends 2700K to 3000K front of house, with one colour temperature across any sightline, so every source reads as the same white.

Choose for the trading hours: a daytime cafe usually sits better at 3000K, which holds up beside daylight; one that becomes a wine bar may prefer 2700K or dim-to-warm sources. Specify Ra 90 or above, with R9 requested separately.

Scenes: Cafe Lighting for the Clock

A cafe lit well at noon and badly at seven has one scene where it needs five:

  1. Morning. Everything up, the back wall at full, the counter brightest.
  2. Midday. Daylight leads; fittings near the window dim on a sensor or time clock, and the back wall stays up.
  3. Late afternoon. Decorative pieces and wall lights come on as the daylight goes.
  4. Evening. Ambient down, wall lights and table lamps up, the counter still the brightest surface.
  5. Clean-down. Full output for cleaning, the cafe's version of the "brighter setting for the hours nobody is drinking" in our bar lighting guide.

An astronomical time clock moves the evening scene with sunset. As our guide to dimming and lighting controls explains, choose the control protocol before the fixture schedule, put each layer on its own dimmable circuit, and remember that "dimmable" is not a specification. Cafes are photographed constantly, and BSI lists flicker and stroboscopic effect among the updates in BS EN 12464-1:2021, so check every dimmed scene on a phone camera at the mock-up.

How It Changes by Project Type

Specialty coffee bar. The counter is the room: spend the budget there and on the back wall.

All-day cafe. If it serves wine at night, design the evening scene first.

Cafe in a lobby, museum or office. Agree colour temperature and scene times with the host building, and make the counter the brightest point.

For Architects: Rules and Coordination

Workplace lighting. In Great Britain, the Workplace Regulations require suitable and sufficient emergency lighting in any room where people at work are specially exposed to danger if artificial lighting fails. HSG38 recommends an average of 100 lux, with a minimum measured illuminance of 50 lux, for work requiring limited perception of detail, with kitchens as a typical example. HSE calls these "the minimum light levels necessary for the health and safety of employees", and following its guidance is not compulsory.

Food hygiene. In Great Britain, Regulation (EC) No 852/2004, in the version that forms part of UK law, says that "Food premises are to have adequate natural and/or artificial lighting." In rooms where food is prepared, excluding dining areas, "overhead fixtures are to be constructed and finished so as to prevent the accumulation of dirt and to reduce condensation, the growth of undesirable mould and the shedding of particles". Archlior's practice over preparation areas is closed, smooth fittings that wipe clean.

Emergency lighting. In England and Wales, the Regulatory Reform (Fire Safety) Order 2005 requires that, where necessary to safeguard relevant persons, emergency routes and exits requiring illumination have emergency lighting of adequate intensity in case their normal lighting fails. In England, Approved Document B, Volume 2 lists among the intentions of requirement B1 that "Escape routes are adequately lit and exits are suitably signed." The UK code of practice is BS 5266-1:2025, published in October 2025 as a full revision of the 2016 edition, with its scope extended to local area and standby lighting. Show emergency luminaires and exit signs on the reflected ceiling plan from the first issue.

Energy. In England, Approved Document L, Volume 2 includes a section on lighting. The 2021 edition incorporating 2023 amendments is current; a 2026 edition takes effect on 24 March 2027 for work not connected with higher-risk building work. Confirm with building control which applies.

Coordination. Fix machine positions before setting pendant drops and keep fittings clear of the steam wand; agree driver access with the shopfitter and controls with the electrical engineer.

Checklist

Window and counter

  • Back wall lit by day; ceiling fittings set back from the glass
  • Window bench given a blind and its own shaded evening light
  • Counter the brightest horizontal surface front of house in every scene
  • Pendant drops checked against the coffee machine and the barista's line of sight
  • Server's face lit from the customer side; nothing bright behind the order point
  • Menu boards lit from the front

Seating and colour

  • Back wall and one long wall washed, with fittings typically 30 to 45 cm from the wall
  • Table lighting checked from a seated position with a laptop open
  • One colour temperature front of house, between 2700K and 3000K
  • Ra 90 or above, R9 requested separately, TM-30 report requested

Controls

  • Control protocol chosen before the fixture schedule; each layer on its own dimmable circuit
  • Five scenes on an astronomical time clock, each checked on a phone camera for flicker

Compliance

  • In Great Britain, overhead fixtures in food preparation rooms finished to prevent dirt build-up and reduce condensation, mould and shedding of particles; Archlior specifies closed, wipe-clean fittings
  • In England and Wales, emergency lighting for routes and exits requiring illumination, where necessary to safeguard relevant persons; BS 5266-1:2025 used as the code of practice
  • In England, edition of Approved Document L confirmed with building control

Five Mistakes

  1. Lighting the front and leaving the back dark. The window lights the front for free.
  2. A window, backlit menu or glossy surface behind the order point. It turns the barista into a silhouette, and in England Approved Document M warns that light sources or reflective surfaces behind a reception point could compromise lip reading.
  3. One scene for the whole day. The morning setting left on at seven in the evening is how a good cafe ends up feeling like a canteen.
  4. A downlight grid over laptops and glass. It reflects in screens by day and in the shopfront by night.
  5. Treating HSE's minimums as a target. HSG38's 100 lux average for work requiring limited perception of detail is a health and safety minimum for staff, not a well-lit cafe.

Frequently Asked Questions

What is the best colour temperature for a cafe? Archlior recommends 2700K to 3000K front of house, one colour temperature in any sightline: 3000K for a cafe that trades mostly by day, 2700K for evening trade. Avoid 4000K in food and drink settings.

How bright should a coffee shop be? None of the sources cited here sets a lux figure for customer seating, so Archlior judges it on a mock-up. For staff, HSE's HSG38 recommends at least 100 lux on average, with a minimum measured illuminance of 50 lux, for work requiring limited perception of detail such as kitchens, as health and safety minimums. Design the counter brighter than the tables.

How high should pendant lights hang over a cafe counter? Manufacturer guidance for kitchen islands puts the bottom of a pendant about 75 to 90 cm above the worktop; in a cafe, the coffee machine and the barista's sightline decide the final height.

Does a cafe need emergency lighting? In England and Wales, the Regulatory Reform (Fire Safety) Order 2005 requires emergency lighting of adequate intensity for emergency routes and exits that require illumination, where necessary to safeguard relevant persons, in case normal lighting fails. BS 5266-1:2025 is the UK code of practice for its design.

What CRI should cafe lighting have? Archlior recommends Ra 90 or above, with R9 asked for separately, and a TM-30 report, especially for lighting over food on display.

How do you light a cafe menu board? From the front, with an even wash from a concealed source, on a matt board. Avoid backlit boards and bright surfaces behind the person taking the order.
