E27 bulb

Start by checking the socket: an E27 lamp is recognised by its 27 mm diameter screw socket, the most common format in Europe. The bulb screws in, can be changed and replaced freely. You then choose the wattage, the light colour and the look of the fixture according to the room to be lit.

What is an E27 lamp and how do you recognise the right socket?

An E27 lamp is a fixture fitted with a 27 mm diameter screw socket. It is the most widespread format in Europe, found on most table lamps, bedside lamps and floor lamps. To recognise it, look at the socket: wide and threaded, it is an E27; narrower, an E14; with two pins, a GU10. The letter E followed by the number is often moulded on the socket itself.

E27 LED lamp: what does it change day to day?

An E27 LED bulb lights without heating, which matters under a fabric shade or in a salt block. It is chosen mainly for its light colour: around 2700 K for a warm white in the evening, towards 4000 K for a more neutral rendering in an office. LED lamps fit the same sockets as classic models, there is nothing to modify on the fixture.

Which fixtures use an E27 socket?

Almost all movable fixtures: table lamps, bedside lamps, desk lamps, floor lamps, but also many wall lights and pendants. Conversely, small recessed spotlights and string lights use other bases. Browsing the lamp collection helps to spot models whose socket is visible, a detail that counts when you want to show a filament bulb.

What is the wattage of an E27 bulb?

The E27 socket accepts bulbs of very different wattages, and it is the lamp, not the socket, that sets the limit not to be exceeded. At comparable brightness, an LED bulb uses significantly less than a halogen or a classic one, and heats much less. The maximum wattage is indicated on the socket, on a label stuck under the base or in the instructions, within our lighting universe as on market models.

E27 lamp 40 W or 60 W: which to choose?

These references come from the era of filament bulbs, when 40 W and 60 W gave two clearly distinct brightness levels. With an LED, it is no longer the watt that decides the rendering but the flux announced by the manufacturer: the same socket can take a discreet accent bulb or a brighter bulb for reading. Stay below the limit marked on your fixture.

Where to read the maximum wattage of a lamp?

Three places, in this order: the socket itself, often marked in relief; a label under the base or in the bulb compartment; the instructions supplied with the fixture. If you find nothing, choose an LED bulb rather than a halogen one: it heats the socket and the wire feeding it less.

Which E27 lamp to choose for the living room, the bedroom or the bedside?

The choice depends on the surface to be lit and the use: a table or living room lamp for atmosphere, a bedside lamp for reading, a floor lamp for a large volume. The larger the room, the higher and wider the diffusion must be, otherwise the light stays stuck to the floor. A reading corner calls for concentrated light, an entrance for a simple accent.

Designer bedside lamp: which shape to favour?

On a bedside table, the constraint is bulk: a narrow base frees up space for the book and the glass of water. Modern bedside models often rely on an opal shade that diffuses without dazzling, while lamps designed for the bedroom play on the softness of warm white.

Living room floor lamp: what use?

A floor lamp lights from above, which suits a living room where you do not want to switch on the ceiling. Place it about a metre from the wall to avoid too marked a shadow, next to the sofa or in the dark corner. Modern living room lamps and floor lamps cover this need, complemented by a table lamp on a low piece of furniture.

How to choose a table lamp or a designer bedside lamp?

A table lamp is chosen first for its look and the space it takes up: a narrow base on a console, a wide shade on a coffee table. For a designer bedside lamp, aim for light directed towards the book, not towards the face. Measure the available height before choosing, a wide shade is quickly noticeable on a narrow table.

Italian design table lamp: what makes the difference

The Italian style is recognised by its simple lines, its fine stems and its opal shades that diffuse an even light. No brand is needed to get close to it: look for a pared-back silhouette among table lamps and designer lamps, with a clearly visible socket and an E27 filament or LED bulb.

What size of lamp for a bedside table?

Simple guide: the lamp should not exceed the width of the bedside table, and the shade should stay above the level of the mattress once seated. A base of twenty to thirty centimetres suits most bedsides; beyond that, the lamp dominates the room. Small bedside lamps remain the easiest to fit in.

How to recognise a real salt lamp?

A real salt lamp is cut from a block of rock salt, never moulded: the surface is irregular, the colours range from pale pink to orange, and the block shows natural veins. A resin or reconstituted lamp displays a uniform tint and sharp edges. Weigh it: a solid block surprises with its density in the hand.

Red light salt lamp: where does this tint come from?

The colour comes from the block itself, which filters the light of the bulb and warms it towards orange. The thicker the block, the deeper the tint; lighter blocks give a pale pink. As the salt lamp uses an E27 socket, you keep the choice of bulb, and a small LED bulb is enough to bring out the tint.

How to look after a salt block?

Salt attracts moisture: avoid the bathroom and damp rooms. A soft, dry cloth is enough for dust, without water or abrasive product. Switch the lamp on regularly, the gentle heat of the bulb drives out surface moisture. Always unplug before changing the bulb, and respect the manufacturer's maximum wattage. Find this type of block in all our bulb lamps.

How to wire several lamps on a single electrical supply?

Several lamps can share the same supply, provided you do not exceed what the circuit supports and avoid stacking connectors. The simplest remains one socket per lamp or a quality power strip, with plugs firmly pushed in. For a recessed connection or a dedicated line, it is better to entrust the work to an electrician: outside sockets, the subject touches the consumer unit and the protections.

Can you plug two lamps into one socket?

Yes, with a correctly sized power strip or socket block. Add up the wattage actually consumed by each bulb and stay below what the socket and the circuit accept. LED bulbs change the equation: they consume little, which allows several to be grouped without approaching the limit. Do not use a bare extension lead or an exposed terminal block.

Should you plan one switch per lamp?

Each lamp keeps its interest with its own switch, placed on the cord or on the base: you switch on the one you want without turning off the others, and you reduce the use of the power strip as a switch. For wall lighting controlled from the entrance, look instead at wall lights and wall lamps.

How to match the material and colour of your E27 lamp?

The material mainly changes the way light bounces: a metal reflects it and makes it more definite, a glass or a fabric shade diffuses it more gently. A gold, black or white finish blends easily with a contemporary interior, provided it stays consistent from one room to another. Two strong finishes per home are enough, beyond that the whole becomes scattered.

Metal or glass lamp: what light rendering?

Metal draws sharp outlines and reflects light downwards or onto the wall; it suits an office or a contemporary style living room. Glass and the opal shade, on the other hand, diffuse an enveloping light, suited to a bedroom. Metal lamps and modern lamps illustrate these two families of rendering.

Gold, black or white finishes: how to stay consistent?

Choose one dominant finish per room and keep it on the fixtures as well as on the handles or furniture legs. Gold finishes warm up a living room or an entrance, matte black marks out an office, white blends in anywhere. A black lamp and a gold one in the same room work if one remains discreet.

How to install and maintain an E27 lamp?

Installation is simple: unplug or switch off the power, screw the bulb in without forcing until it makes contact, then test. For maintenance, a soft cloth is enough, and abrasive products are avoided on metal as on a salt block, which fears moisture. Affordable models are treated in the same way.

How to change an E27 bulb without forcing?

Let the bulb in place cool down: even an LED heats slightly, and a halogen much more. Turn anticlockwise, without gripping the socket between two fingers through the shade. When refitting, screw in until contact, without locking: forcing damages the thread and makes the next change more difficult.

How to clean a fixture depending on its material?

Metal: dry or very slightly damp microfibre cloth, then dry immediately. Glass and opal shade: warm water and mild soap, never alcohol. Fabric: soft brush or lint roller. Salt block: dry cloth only. In all cases, cut the power before cleaning around the socket.
