Lighting an apartment through a northern winter

Between late November and early February, Luxembourg gets roughly eight hours of daylight and a good share of it arrives filtered through cloud. An apartment that feels generous in June can feel like a waiting room in January, and the reason is almost never the paint. It is that the room has one ceiling fitting, a cold colour temperature and nothing at eye level. Fixing that costs a few hundred euros and no permission from anyone.

Start with the problem, not the fitting

A single central pendant lights a room from above, flattens every face in it and throws shadows downward. It is efficient and unpleasant. What a room actually needs in winter is light at three heights, so that the eye has somewhere to rest and the corners are not black.

The working principle is simple. Aim for at least three separate light sources in any room you spend the evening in, on at least two switches. Below that, the room only has one mood, and in a northern winter that mood is fluorescent.

The three layers

• Ambient. The general wash. Ceiling fitting, wall lights or an uplighter. This is what you switch on when you walk in and it should rarely be the only thing on.
• Task. Directed light where something happens. A reading lamp beside the chair, a lamp on the desk, under-cabinet strips over a worktop.
• Accent. Low, warm, decorative. A table lamp on a sideboard, a floor lamp in a corner, a picture light. This is the layer most apartments are missing entirely, and it is the one that does most of the work.

Colour temperature, and why most apartments get it wrong

Colour temperature is measured in kelvin, and the number on the box matters more than the wattage equivalent.

• 2700K is warm white. This is what a living room, a bedroom and a dining table should be. It is close to the old incandescent bulb and it flatters skin, wood and textiles.
• 3000K is neutral warm. Acceptable in a kitchen or bathroom where you want a little more clarity.
• 4000K and above is cool white and blue-heavy. It belongs in a garage or a utility room. In a living room it reads as institutional, and in a northern winter it makes an already grey room feel colder.

The second number to check is the colour rendering index, or CRI. Anything below 90 renders colour badly, which is why cheap LED strips make oak look grey and terracotta look brown. Buy 2700K, CRI 90 or above, and ignore almost everything else on the packaging.

What to do when you cannot touch the wiring

Most tenants and many owners in a co-ownership cannot add circuits, move switches or cut into ceilings without a conversation they would rather not have. Everything below works from a plug socket.

• Floor lamps in corners. An arc or uplighter in the darkest corner does more for a room than any ceiling change. Corners are where a room's depth lives.
• Table lamps at eye level when seated. Roughly 40 to 55 centimetres of lamp on a 70 centimetre surface. This is the single most reliable improvement available.
• Rechargeable portable lamps. The category has improved enormously. They solve dining tables with no pendant, balconies, and the corner with no socket.
• Plug-in dimmers and smart bulbs. A dimmable warm bulb in an existing fitting turns one bad light into three usable ones. Choose bulbs that dim warm rather than staying at a fixed temperature.
• Swap the shade before the lamp. A linen or parchment shade diffuses; a metal or glass one throws a hard pool. Half of what people dislike about a lamp is the shade.

Room by room

Living room

Ceiling fitting on a dimmer, a floor lamp behind or beside the main seat, a table lamp on a side unit, and if there is a bookcase, a strip or picture light on it. Four sources, two switches. Never light the middle of the room and leave the perimeter dark.

Bedroom

The bedside lamps matter more than the ceiling light. Two matched lamps with a warm bulb and a shade, positioned so the light falls on the book rather than in the face of the person next to you. If there is space for only one bedside surface, wall-mounted swing-arm lamps free the table and are usually plug-in.

Kitchen

Under-cabinet lighting is the highest-value intervention in any kitchen, and stick-on rechargeable versions exist for rentals. Overhead light alone means you work in your own shadow.

Bathroom

Light beside the mirror rather than above it. A fitting above the mirror casts shadow into the eye sockets, which is why hotel bathrooms with vertical lighting feel better than the one at home.

A shopping list for one room, in order

If you are starting from a single ceiling fitting and want to fix a living room in one afternoon, buy in this sequence and stop when the room feels right.

• A dimmable 2700K bulb for the existing ceiling fitting, plus a plug-in or in-line dimmer if the switch is not dimmable.
• One floor lamp for the darkest corner, ideally around 150 to 165 centimetres tall with a fabric shade.
• One table lamp for the surface beside where you sit, roughly 45 centimetres tall.
• A second table lamp diagonally opposite the first, so the room is lit from two sides rather than one.
• A rechargeable portable lamp for the dining table or the balcony, which solves the places with no socket.

Buy the bulbs separately and deliberately. Most lamps are sold with no bulb or with a poor one, and the bulb is the part that determines whether the lamp was worth buying. Warm, dimmable, CRI 90 or above, every time.

Three questions we are asked

How many lumens do I need?

As a working figure, a living room reads comfortably at somewhere between 1,500 and 3,000 total lumens spread across several sources, and a bedroom at rather less. The total matters far less than the distribution. Three lamps of 400 lumens beat one of 1,200 every time.

Are smart bulbs worth it in a rental?

They are one of the few genuinely portable upgrades, since they leave with you. The practical case is dimming and scheduling in a flat where the switches are in the wrong places. Choose a system that also works from a physical switch, because guests and flatmates will not open an app.

Can I put lighting into a rented apartment permanently?

Anything that involves the fixed wiring needs the owner's written agreement, and in an apartment building work affecting communal circuits may also concern the syndic. Plug-in solutions avoid the question entirely, which is why almost everything recommended here is plug-in.

Where this fits in a Luxembourg apartment

Every furnished apartment and room we let is lit on this principle: warm bulbs, several sources, nothing above 3000K. It costs very little and it is the first thing people notice at a winter viewing.

We furnish and let apartments and rooms across Luxembourg City, and we prepare properties for sale. If you want a second opinion on a specific room, send a photograph and the dimensions on WhatsApp, or look at how the apartments on our rentals page and our sales listings have been put together.

It is tempting to assume that a shopping list for one room, in order is automatically positive, but a serious property guide should also test the opposite case. For the question raised by “A shopping list for one room, in order”, the useful detail is not a generic list of advantages.

For where this fits in a luxembourg apartment, note what you can see, what you can measure, what you need to ask and what would be expensive to change. For the question raised by “A shopping list for one room, in order”, the useful detail is not a generic list of advantages.

A useful way to test three questions we are asked is to run a normal-day scenario.
