Checkout counter notes need named planes
A retail checkout counter is not one lighting surface. It usually has a horizontal counter plane, a receipt or document face, a payment face, a customer-facing vertical zone, staff face planes, queue visibility, nearby display faces, glare paths and lighting control states. Keeping those items separate makes the note easier to compare with estimates later.
This page sits inside the wider retail lighting sector note set, but its scope is the counter bay only. The task-plane notes table separates counter top, document, payment and face planes. Aisles and shelf labels belong with retail aisle and shelf lighting notes. Feature bays sit with retail display lighting notes. Mirror and garment checks sit with fitting-room mirror lighting notes. For upright counter faces, the broader vertical illuminance notes guide gives the companion language.
| Counter item | Plane to name | Note beside the value |
|---|---|---|
| Counter task surface | Horizontal task plane on the writing, scanning or packing area. | Counter depth, working side, mounted equipment shadow and active scene. |
| Receipt or document face | Slightly tilted or vertical paper face at normal hand position. | Paper angle, staff side, customer side and whether the paper is glossy or matte. |
| Payment face | Terminal screen, keypad or tap face as seen from the customer side. | Face angle, reflected light, nearby source view and control state. |
| Customer-facing counter front | Vertical front face, small sign face or bagging ledge. | Viewing distance, queue side, finish colour and reflected glare note. |
| Staff face plane | Vertical face-height plane behind the counter. | Position, posture, shadow from canopy or shelf, and opposite bright surface. |
| Queue view | Customer eye-line toward the counter and document area. | Queue position, sightline, nearby display brightness and scene name. |
A single counter average can hide the reason a note feels wrong. A bright horizontal value may still leave a payment face unreadable from the queue side, while a strong vertical face reading may say little about the writing or wrapping surface.
Separate the counter plane from payment and document faces
The horizontal counter plane is useful for tasks performed on the counter top. Payment and document faces are different because they are tilted or vertical, often glossy, and viewed from a tighter angle. Measured illuminance should therefore be tied to the exact plane, meter orientation and active scene.
For estimates, a lux to lumens estimate can describe a named counter target, while a lumens to lux comparison can compare stated output over a stated area. A broader room lighting estimate may describe the tenancy or counter bay, but it should not replace the separate payment face and document face notes.
| Note line | Good wording | Boundary |
|---|---|---|
| Counter top | Counter task plane, staff side, normal counter scene. | Does not describe vertical payment or receipt faces. |
| Receipt face | Receipt paper face, vertical or tilted meter, customer side noted. | Does not prove every document size or paper finish. |
| Payment screen | Payment face from customer side, reflected source noted. | Does not address payment processing or data handling. |
| Keypad or tap face | Payment control face, normal standing distance, glare note. | Does not cover device setup or payment outcome. |
| Counter front | Customer-facing vertical plane, queue side view. | Does not stand for aisle, shelf or wall display lighting. |
Where field readings are taken, keep point labels short and repeatable: "Counter top centre", "Receipt face", "Payment face", "Customer front" and "Staff face". The lux meter reading notes table keeps the point, plane, meter direction, lighting state and daylight note together. Repeated points can be summarised with the lux meter average when the same plane and scene are being averaged.
Queue visibility and face planes
Queue visibility is about what customers can see before they reach the counter. It is not an aisle note and it is not a claim about speed or commercial outcome. The useful note is more modest: customer eye-line, payment face, counter front, staff face plane, queue-side glare and the active lighting zone.
Face planes should stay distinct from document planes. A staff face-height vertical reading can describe one interaction position. A customer face plane may describe the queue side or the point directly in front of the counter. These values sit beside, not inside, the counter task-plane note. The vertical illuminance term is helpful here because it names upright light on faces and signs rather than light on the counter top.
| View position | Plane or object | What to note |
|---|---|---|
| First queue point | Counter front and payment face from approach view. | Distance, eye-line, nearby bright display and scene. |
| Counter standing point | Receipt face, payment face and customer face plane. | Meter direction, surface angle and whether hands shade the face. |
| Staff position | Staff face plane and counter task plane. | Overhead shadow, back-wall brightness and active counter zone. |
| Side queue | Counter side face or end display face. | Side reflection, display contrast and whether the main counter face is visible. |
| After-dark state | Same planes under after-dark scene. | Scene name, dimmed level and daylight absence. |
Queue and face notes are clearest when written as observed conditions, not promises. "Payment face has a bright reflection from customer side under evening scene" is clearer than a broad statement that the counter is unsuitable.
Colour quality at the counter
Colour notes at a checkout counter should name the surface being judged. White-light appearance, CRI or Ra, counter finish, document colour and daylight mix can all change the view. Colour temperature describes warm, neutral or cool appearance. CRI/Ra gives a colour-rendering cue. Neither one proves comfort or brightness on its own.
Keep colour information beside the plane. The colour quality notes table gives a compact schedule shape, the CRI ratings table keeps notation consistent, and the colour temperature table supports Kelvin wording. A colour temperature comparison can help keep CCT labels consistent between counter, display and queue notes.
| Counter surface | Colour field | Extra note |
|---|---|---|
| Receipt or document face | CCT and CRI/Ra under the named counter scene. | Note paper colour, print contrast and gloss. |
| Payment face | CCT, screen brightness setting if visible, and reflected source. | Keep screen reflection distinct from paper notes. |
| Counter top | CCT, CRI/Ra and counter finish colour. | Pale, dark or glossy tops can change perceived contrast. |
| Customer-facing vertical face | CCT and finish colour from queue side. | Nearby display brightness can change the visual balance. |
| Staff face plane | CCT and adjacent wall or shelf colour. | A bright rear wall or dark canopy can shift perceived face balance. |
Do not let colour-quality fields replace measured values. They explain the viewing condition for the note; they do not prove the counter lux, glare condition or energy estimate.
Glare, reflections and nearby displays
Checkout counters often sit near glossy surfaces, small screens, glass panels, polished counter tops, bright wall graphics or window daylight. Glare notes should describe the observer position and reflected surface. The glare check lighting notes guide keeps the language practical: observer side, source view, reflected surface, scene and measured point.
Display notes still have their own page. A counter-adjacent poster, wall bay or bright vertical surface can be noted as context, while a display wall itself belongs with display wall lighting notes. That split keeps the counter note focused on task, payment, document, face and queue planes.
| Glare condition | Counter note | Why it matters |
|---|---|---|
| Payment face reflection | Reflected bright source visible from customer side. | A readable lux value may still be hard to view. |
| Glossy counter top | Bright line across wrapping, writing or document area. | Horizontal readings do not explain reflected source shape. |
| Rear wall brightness | Staff face seen against a much brighter rear surface. | Face plane and background should be recorded separately. |
| Queue-side display | Bright side display visible before the counter. | It can distract from payment or document faces. |
| Window daylight | Daylight reflection on payment or counter face. | Day and after-dark notes may not match. |
Short glare notes are enough when they are tied to a point label. "Customer side payment face, reflected source at upper right, normal scene" is more repeatable than a general note about harsh lighting.
Control state and energy notes
Controls matter because the same counter can read differently under morning, daytime, evening, after-dark or cleaning scenes. The lighting control notes table keeps zone, scene, dimmed level, daylight condition and active group beside each reading. The note should say whether the counter, queue side, rear wall and adjacent display are controlled together or separately.
Energy comparisons should stay distinct from visual notes. A lighting power density estimate can describe connected load over an area, and business lighting energy notes can keep operating hours, zones and scenes together. Those notes do not prove counter visibility, colour quality or glare; they simply give the energy side its own line.
| Control or energy field | Note wording | Keep distinct from |
|---|---|---|
| Counter zone | Counter task zone, normal scene, dimmed level if known. | Queue-side display and rear wall zones. |
| Queue zone | Queue face and counter-front zone, same scene or separate scene. | Counter top task plane. |
| Daylight state | Blinds, window side, direct sun, overcast or after-dark. | Fixed all-day performance claims. |
| Connected load | Area, connected watts and zone boundary. | Visual quality on document, payment and face planes. |
| Operating scene | Named scene and hours band. | Mandatory lux value or energy outcome claims. |
This separation keeps a bright counter note from being confused with energy performance, and keeps an efficient energy line from being treated as proof of payment-face visibility.
Compact counter note
A compact checkout counter note can be one table row per counter bay if the fields are precise. Name the zone, plane, point label, reading or estimate type, colour fields, glare note, control state and boundary note. Keep the wording plain Australian English and avoid folding unrelated retail areas into the counter page.
| Field | Example note wording |
|---|---|
| Zone | Front counter, left register bay, queue side and staff side named. |
| Plane | Counter top task plane, payment face, receipt face, staff face or customer-facing vertical plane. |
| Measurement | Point label, lux value, meter orientation and measured illuminance condition. |
| Estimate | Counter area checked with lux to lumens estimate or output checked with lumens to lux comparison. |
| Colour | CCT, CRI/Ra, finish colour and comparison rows from colour quality notes. |
| Glare | Observer side, reflected surface and source view linked to glare wording. |
| Controls | Zone, scene, dimmed state and daylight note from lighting control notes. |
| Boundary | Planning note only; read the disclaimer before treating estimates as design evidence. |
Related notes stay useful when they keep their own page promise. Counter notes handle task, payment, document, face, queue, glare and control assumptions. Aisle, shelf, display wall and fitting-room notes stay separate so each surface can be compared on its own terms.
