LED bathroom light bulbs

A bathroom LED bulb is chosen first by its base, here E27, then by its colour temperature: warm white from 2700 to 3500 K flatters complexions in front of the mirror. Next, check the IP rating of the fixture that houses it, because the bulb alone does not protect against humidity.

Which LED bulb for a bathroom?

Above a vanity unit, a round glass bulb spreads a soft, enveloping light: the reflection on the glass stays gentle, with no hot spot that dazzles. The sphere distributes light to the sides, and brass keeps its finish over time. Four points to check before buying.

Bulb for a bathroom fixture: the four criteria

The base first: a the most common screw base fits most wall lights, ceiling lights and pendants. Then the temperature, between 2700 and 3500 K, for a warm rendering that does not turn yellow on the tiles. The IP rating of the fixture matters more than that of the bulb, because it is the fixture that blocks steam. Finally, dimmer compatibility, to lower the intensity in the evening. If you are hesitating between several families, browse all the LED bulbs in the catalogue before making your choice.

What the bulbs in this selection share

Glass and brass, in beige, gold or white, a ball shape 4 cm in diameter and 6 cm high: enough to fit into a compact fixture, something to check when the socket is deep. All are guaranteed for two years. The flagship model, the round vintage E27 LED bulbs, sums up this approach: a standard base, glass that softens the light, a discreet vintage look.

Recessed bathroom LED spot or screw-in bulb: how to decide?

A recessed spot goes through a false ceiling and concentrates light on one point; an E27 screw-in bulb can be changed without tools and fits a wall light, a pendant or a ceiling light. The choice therefore depends on the fixture already in place, not on the bulb alone: start by looking at the socket and the IP rating.

Recessed LED spot for a bathroom: what it requires

You need to make room in the false ceiling, run the power supply and accept a socket that is often GU10 or GU5, smaller than E27. A spot suits a line of light above the vanity unit or in a niche. For this type of installation, compare GU5 bulbs for recessed spots with a standard E27 bulb before drilling.

LED spot for bathroom furniture: light close to the surface

Under a shelf or inside a drawer, strip lights and furniture spots illuminate without dazzling: the light grazes the surface and highlights the material. These points of light add to the general lighting. For the fixture that houses them, see the lighting for the home and bear in mind that the E27 bulb in this selection will not fit into a narrow spot housing.

LED bulb for a bathroom mirror: which light for the face?

Above or on either side of the mirror, a warm white light of 2700 to 3500 K renders complexions more accurately than a cool white. Light the face from the front rather than from above, otherwise shadows mark the eyes. A round glass bulb diffuses widely, without harsh reflections on the glass.

LED spot for a bathroom mirror: from the front rather than from above

A single point of light on the ceiling hollows out the features and lengthens shadows under the nose. Two side sources, or a wall light above the mirror at face height, give a more faithful rendering for shaving or applying make-up. Steam settles on the glass whatever the bulb: none of the bulbs in this selection is described as anti-fog, it is the fixture and ventilation that do the work.

LED bulb for a bathroom mirror: 2700, 3000 or 3500 K?

At 2700 K, the light is warm, pleasant in the evening, a little yellow for checking complexion. At 3000 K, it stays warm but crisper, suited to everyday use. At 3500 K, it becomes frank without turning cool white, handy for the grooming area. 3000K bulbs are the most common compromise.

Is an IP20 LED bulb suitable in a bathroom?

An IP20 bulb is protected against solid objects larger than 12.5 mm, but not against water or steam. In a bathroom, it must therefore stay inside a closed fixture, out of reach of splashes from the bath or shower. It is the IP rating of the fixture that provides safety, not that of the bulb.

What an IP20 rating protects against

The first digit covers solids, the second liquids: here, zero protection against water. An IP20 bulb in a closed ceiling light, away from the bath, poses no difficulty. The same model left bare above a bathtub, without a diffuser, is not being used as intended.

Where to install the bulb to stay clear of splashes

Above the vanity unit, on the central ceiling, or in a pendant above a dry spot. Near the shower, choose a closed, fixed fixture, and pick it from the lighting for the home while checking its rating. A glass bulb stays easy to wipe if the room is humid.

Is 400 lumens a lot for a bathroom?

400 lumens is a moderate output: enough to provide an additional point of light above a mirror, not to light a whole bathroom on its own. How it feels depends on the size of the room, the height of the fixture and how light the walls are. It is better to multiply discreet sources than to rely on a single very bright one: a wall light, a ceiling light, a niche, each with its own bulb.

Dimmable LED bulb and warm white: how to set the mood?

The bulbs in this selection are dimmer compatible, which lets you go from a crisp working light above the mirror to a soft mood in the evening. The warm white range, from 2700 to 3500 K, keeps a warm rendering without turning yellow in a room that is often tiled.

Dimmable LED bulb: what to check on the switch side

Bulb compatibility is not enough: the wall dimmer or switch must accept an LED load, otherwise the light flickers or goes out at the bottom of the range. Dimmer-compatible bulbs are identified on their product page, and the E27 dimmer bulb remains the simplest combination to install in an existing fixture.

2700 K, 3000 K, 3500 K: which mood for the bathroom?

In the morning, turn up the intensity for a crisp light for shaving; in the evening, turn it down without changing the bulb. A 3000 K base handles both uses, a 2700 K base leans towards comfort, 3500 K towards precision. To fine-tune, compare 2700K bulbs and 3000K bulbs on the same wall light.

How to install and care for a round glass and brass LED bulb?

Switch off the power at the breaker, let the bulb cool, then screw it into the E27 socket without forcing: glass cracks when you tighten by the sphere. A soft cloth is enough for the glass, a dry cloth for the brass. Check that the fixture supports the weight and stays closed.

Screwing an E27 into a bathroom fixture without forcing

Hold the bulb by the base, not by the ball, and screw it in until it makes contact without tightening it like a bolt. Check that the 6 cm height fits under the diffuser, otherwise the sphere touches the glass of the fixture. An E27 LED bulb can then be replaced without tools, which matters in a room where you have to stand on a stool.

Cleaning a glass and brass bulb without scratching it

With the power off and the bulb cold, wipe the glass with a slightly damp microfibre cloth, then dry it. For the brass, a dry cloth is enough: abrasive products and scouring pads mark the finish. Avoid spraying directly onto the base.

How to harmonise the bathroom bulb with the rest of the home?

The same E27 base and the same warm white range of 2700 to 3500 K from one room to another avoid breaks in tone when you move from the bathroom to the living room or the kitchen. Consistency comes from the colour temperature and the finish, not from the exact model.

The same warm white from the bathroom to the kitchen

Moving from one room to another is most noticeable in the tones: a cool white above the sink and a warm white in the bathroom create a break. Keep the same base and the same temperature, then adapt the shape to the fixture. This is just as true for a bulbs for the kitchen as for a bulbs for the living room, and even for the bulbs for the bedroom. If you are redoing a modern kitchen decor, an E27 filament in filament bulbs extends the bathroom style without dissonance. Kitchen decoration benefits from carrying over the same family of vintage-look E27 filament.

Entry level or exceptional piece: where the budget sits

This E27 bulb measures 4 cm in diameter and 6 cm in height, with an IP20 rating and dimmer compatibility. The current price is shown on each product page. For a light finish that matches the tiles, look at the white bulbs.

Secure payment, tracked delivery, returns and Designix customer service: the order can be tracked, and an exchange remains possible if the socket does not match.
