Lighting a café under 80 m²: one pool of light per table

A café under 80 m² doesn’t need even light. It needs a pool of light on every table: one lamp hung low over each table, its bottom 70 to 80 cm above the tabletop, a 2700K bulb, aisles and walls left darker than the tables, and a slightly brighter bar on its own switch. All of it can go in overnight while you are closed, and you open the next morning as usual.

I’m Hà. Before I started the workshop in 2021 I spent seven years making lamps for cafés, and the first lamp Đèn Hạ Chí ever made was for a friend’s café. This note is for owners renovating or about to open: layout, colour of light, switching, and one worked example with the full price, wattage and timeline.

Why evenly lit cafés feel like offices

This is what I have seen in the cafés we have worked on, not a research finding. A café lit by a grid of recessed downlights on one switch has every table as bright as the next, the aisles as bright as the tables, the walls as bright as the bar. In daytime that’s fine. At night the room looks like an office: nowhere to sit a little apart, nothing drawing your eye to your own table.

Thềm Chiều café in Nhiêu Lộc ward (old District 3) came to us for exactly this. Forty seats at twelve tables in a townhouse down an alley, a 3.6 m ground-floor ceiling, walls finished in earth-coloured lime plaster. The old downlights lit it evenly from the door to the back wall.

The fix isn’t more light. It’s moving the light: down onto the tables, with the rest of the room left dimmer. Each table becomes its own pool, and the aisles between them are the darker gaps that keep tables apart.

One lamp per table

The rule: lamps follow tables, not the ceiling grid. Draw the tables on the floor plan first, then put a lamp over the centre of each. However far apart two tables are, that’s how far apart their lamps are.

Height, measured from tabletop to the bottom of the lamp:

The 70 to 80 cm range is our workshop’s practice, close to the dining-table guidance we have read (Lightnox gives 60 to 75 cm). How to measure, and other sources, are in how high to hang a pendant over a dining table.

Pendants never hang over aisles. Bock Lighting gives a minimum of 7 feet (about 2.13 m) of clearance under fixtures over walkways; we keep at least 2.1 m. In a café, staff carry trays through all day, so anywhere without a table underneath gets no pendant.

Do tables get moved? Small cafés often push two tables together for groups. We ask first which tables get joined and which stay put. For tables that get joined, each lamp hangs over the centre of the single table, so a joined pair still has two pools.

Which lamp where

The café set covers eight lamps or more. Its price is the sum of the lamps you choose plus VND 2,800,000 for the light mock-up on your floor plan, the circuit layout and one overnight installation. The minimum is VND 18,000,000: eight Lập Thu (8 × VND 1,900,000 = VND 15,200,000) plus VND 2,800,000.

2700K or 3000K for a café

LEDVANCE describes 2700K as a warm, soft light similar to incandescent bulbs, suited to restaurants and hospitality because it feels warm and intimate. 3000K is a balanced warm white with fewer yellow and orange tones, suited to places where people need to see more clearly, such as hotel lobbies, corridors and offices.

All our lamps use 2700K bulbs with an E27 base (the standard screw-in size sold in any electrical shop in Vietnam), 6 W. For guest tables we keep 2700K. The bar is the one place that may differ: the barista needs to see the colour of the coffee, the milk, the lines on the jug. We handle that by hanging the bar lamps closer together and giving them their own switch, not by changing colour. If your barista still wants 3000K, any E27 bulb from a shop fits our sockets; change it at the bar only, and come and see both colours side by side at the workshop before you decide. The two are compared in detail in 2700K vs 3000K.

Dark walls, a brighter bar: circuits and switches

We split a small café’s lamps into at least two circuits:

1. Table lamps. Every lamp over a guest table on one switch, on from dusk to closing.
2. Bar lamps. A switch of their own, so staff can turn them on earlier when opening up and leave them on later while cleaning.

The walls get no lamps of their own. The light that escapes sideways through rattan shades is enough to pattern the wall near each table; the far walls stay dark. At Thềm Chiều, the earth-coloured lime walls get only the sideways spill from the rattan, with no wall lights at all.

To change brightness through the evening (brighter in the late afternoon, softer late at night), add dimmable bulbs (VND 90,000 each) and wall rotary dimmers (VND 350,000 per switch). For example, if a café like Thềm Chiều wanted all 15 bulbs dimmable on two circuits: 15 × VND 90,000 + 2 × VND 350,000 = VND 1,350,000 + VND 700,000 = VND 2,050,000. Thềm Chiều didn’t take this option; the sum is only there for reference.

Installed in one night

A small café can’t close for a whole day. The café set includes one overnight installation: we arrive after you close and finish before you open the next morning. That works because everything is settled on the drawing beforehand:

On the night, Khang brings the circuit plan and every lamp numbered by table. Heights are set on site. I measure the light on the tabletops with a handheld lux meter and compare it with the mock-up.

The full example: Thềm Chiều café

Vy, the owner, wanted the café to have corners at night. We hung twelve Hạ Chí pendants at Ø35 over the twelve tables, on 2 m cables so the bottom of each lamp sits 80 cm above the table under the 3.6 m ceiling. The bar has one Tiểu Mãn set of three. The walls stay dark.

With 8% VAT: VND 41,385,600. The café has 12 + 3 = 15 bulbs at 6 W each, 90 W in total. What those 90 W cost in electricity each month, and how to work it out for your own café, Khang covers in what a café’s lamps cost in electricity.

Timeline: 48 hours to the first mock-up, two rounds of changes, three weeks of making, one night of installation. As Vy put it: “The mock-up even had the light on the tabletops. When it was all up, standing at the door, it looked exactly like the picture.” Drawings and details are on the Thềm Chiều project page.

What changes for a homestay

A homestay of under 15 rooms uses the same approach in the shared lobby (one set over the dining table, darker walkways), but bedrooms are a different problem: a bedside light you can read by without glare when you lie down, and materials that cope with damp in a town like Đà Lạt. Khang covers that in lighting a homestay in Đà Lạt.

Where people go wrong

• Hanging pendants on the old downlight grid. The old outlets follow the grid; the tables don’t. Pendants on the old outlets light the aisles.
• One colour on the tables, another from the ceiling. 6500K downlights on with 2700K pendants put the whole room off-colour. If you keep the downlights, give them their own switch and use them only for cleaning.
• Hanging high because the ceiling is high. A 3.6 m ceiling doesn’t mean lamps at 3 m. Measure from the tabletop, 70 to 80 cm, and order the cable that takes.
• Forgetting the bar. It needs more light than the tables and its own switch.
• Installing by day. A day closed is a day of takings lost. Settle everything on the drawing and install overnight.
• Choosing lamps before looking at the floor plan. In under 80 m², moving a couple of tables changes the whole layout.

How we do it at the workshop

Send us the floor plan (hand-drawn is fine, with measurements), a few evening photos of the café with its current lights, the ceiling height and the number of tables. I draw the light mock-up on the plan and on the photos, number every lamp by table, and send it within 48 hours, the first version free. We take on cafés and restaurants under 80 m² and homestays under 15 rooms. We make no more than thirty lamps a month, so a fifteen-lamp café takes about half a month of the workshop’s time. Tell us early if you have a fixed opening date.

The full offer is on our hospitality page, or send your photos and floor plan to start. To see the lamps lit first, book a visit to the workshop in Gia Định ward (old Bình Thạnh), Tuesday to Sunday, 9:00 to 18:00.
