Wireless light bulbs

A rechargeable light bulb turns on without a plug or wiring: you charge it, then screw it into an existing socket or place it in a portable holder. Here is how it works, which base to check before buying and which room it serves best.

How does a rechargeable light bulb work?

A rechargeable light bulb runs on a built-in battery: it turns on without being connected to the mains and charges from a USB plug or its base. The light comes from LEDs, and control goes through a switch on the base, a remote control or a sensor. This collection has a single product; its specifications are in the table below.

Rechargeable light bulb: what recharges, and how

The battery pack sits in the body of the bulb, above the base. It charges through a USB cable, sometimes on a base where the bulb rests, sometimes through the remote control that doubles as a stand. That is the only time the bulb touches electricity. Once charged, it screws into the socket of the matching base, powered or not. To compare with a mains model, see all the bulbs in the catalogue.

How the rechargeable light bulb works, and what sets it apart from a connected one

The battery powers the LEDs and a small circuit handles switching and brightness. Do not confuse it with a connected bulb, WiFi or Bluetooth: that one is controlled from a phone but stays screwed into a live socket, it needs the mains. A rechargeable light bulb does without any power supply while in use. To dress the room around it, browse all our light fittings.

Where to install a rechargeable light bulb in the home?

A rechargeable light bulb is useful wherever running a power supply would be complicated: a bedside table without a socket, a pendant above a table, a shelf, a cupboard, a garden shed or a wall light. It screws into an existing socket or sits in a portable fitting.

In the bedroom and on a bedside table

A bedside lamp without a socket next to the bed changes the evening routine: you turn the switch on the bulb and read without getting up. A warm white makes the room calmer. Allow space for the USB cable on the table; for more ideas, see bedroom lighting.

In the living room, in a pendant or on a shelf

Above a table, the bulb saves you from reconnecting the supply of a pendant that is already fitted. On a shelf or in an open unit, it lights a corner without multiplying extension leads. Amber glass or a visible filament gives the fitting character: find these finishes in bulbs for the living room.

Rechargeable light bulb with a switch or with a remote control: which to choose?

The built-in switch suits a bulb you turn on by hand, close to you: bedside, cupboard, table. The remote control lets you switch on from a distance a bulb placed high up, in a pendant or a ceiling light. Both controls can coexist on the same model.

Rechargeable light bulb with a switch

The switch is on the base or on the side of the body: you press it or turn it, and the bulb lights up with no accessory to store. It is the choice for a bulb within reach, on a bedside table or in a cupboard. Its limit is simple: you have to reach the bulb.

Rechargeable light bulb with a remote control

The remote control handles switching and often brightness from the sofa, without getting up. It suits a bulb placed high up, in a dining room pendant or a wall light. Remember the remote's battery and where you put it down. A sensor does the same job without any gesture in a hallway, with the risk of triggering as you pass.

How to recharge and make a rechargeable light bulb last?

A rechargeable light bulb charges through a USB cable, sometimes on a base or a stand-remote. To make it last, recharge it before the battery is empty, avoid leaving it in direct sunlight and choose a moderate brightness: runtime drops as light output rises.

USB charging or on a base

Check access to the plug before fitting the bulb: under a tight shade, the USB port can become unreachable. A base or a stand-remote avoids this problem, as the bulb charges while resting. The cable plugs into an ordinary phone charger, with no special equipment.

What reduces runtime

High brightness drains the battery faster; a hot room or a nearby radiator does too. Lowering the brightness in the evening, recharging before a full discharge and storing the bulb out of the sun extend its use. No battery lasts forever: in a heavily used spot, a second model helps.

Base, socket, thread: how do I check that a rechargeable light bulb will fit my fitting?

You need to note the base of the socket before buying: E27 for large screw bases, E14 for small ones, GU10 and GU5 for pin spots. Some rechargeable light bulbs have no thread and sit in their own holder. The socket diameter and the shape of the fitting matter as much as the base.

Rechargeable light bulb without a thread: models with no screw base

These models attach by magnet, by clip, or simply rest in a dedicated holder: there is no thread to match, but a housing specific to the manufacturer. Check the fixing method before buying, a bulb without a thread does not screw in anywhere. Also see the other bases, G4 and G9.

Rechargeable light bulb E14 for small sockets

The small screw thread is found on bedside lamps, wall lights and small pendants. The battery thickens the body of the bulb: measure the clearance under the shade and the space around the socket. The catalogue small E14 bases shows the available shapes, and bulbs with an E27 base cover large sockets.

Which light temperature for a rechargeable light bulb?

For a living room or a bedroom, a warm white around 2700 K gives a soft, restful light; 3000 K stays warm but a little crisper, suited to reading or a worktop. Amber glass or a visible filament warms the result further, especially in a bare fitting.

Warm white 2700 K or 3000 K: what changes to the eye

At 2700 K, the light leans towards the warm yellow of evening, ideal for a bedside or a reading corner. At 3000 K, it becomes whiter, which helps distinguish shades on a worktop. For a softer result, compare 2700K light and a 3000K white.

Dimmable bulb: adjusting brightness on a rechargeable light bulb

A dimmer lowers brightness in the evening without changing the colour: real visual comfort for a bedside or living room bulb. Not every bulb accepts it, and on a rechargeable model dimming is often done from the remote control. Compatible versions are gathered in dimmer-compatible models.

How to light a wall or a ceiling without running a cable?

Without wiring, two options exist: a wired wall light, which requires an electrical supply, or a rechargeable light bulb placed in a wall holder or a pendant that is already fitted. For a ceiling light without drilling, you rely on an existing fixing or choose a battery-powered fitting.

Wired wall light or battery-powered wall lamp

A wired wall light connects to the mains or to a wall outlet: with no cable reaching the wall, it cannot work. In that case, a rechargeable light bulb fixed in a wall holder gives a similar result with a much simpler installation. The look of filaments can be seen in visible filament bulbs, and warm tones in amber-tinted bulbs.

Ceiling light without drilling: what to check first

Reusing the fixing point and supply of a fitting already in place avoids drilling; check the weight it supports. Creating a new point requires drilling. If three sockets must light up together, wire them in parallel: each live wire starts from the previous one and each neutral follows the same path. On a recessed spot, cut the power, remove the spot by pulling on the trim or unscrewing the ring, then unscrew or unplug according to the base, without forcing the reflector.

Which mistakes to avoid before buying a rechargeable light bulb?

Three mistakes come up again and again: buying without checking the base of the socket, confusing a rechargeable light bulb with a connected bulb, which needs the mains, and overestimating runtime in prolonged use. Also check that the bulb fits under the shade and that charging stays accessible once in place.

Do not confuse rechargeable, connected and powerless

A connected bulb stays on the mains: without a power cable in the strict sense, it is useless in an unpowered socket. A rechargeable light bulb, on the other hand, charges and installs anywhere. An LED strip stays wired: strip the two wires, note the plus and minus marked on the strip, then connect to the supply with a connector block or crimp connectors, never by twisting.

Check the bulk and access to charging

The battery adds length and diameter: under a narrow shade, the bulb may not fit, or may block the USB port. Note the free height above the socket and the opening of the fitting before ordering. For a complete fitting rather than a bulb, compare our range of light fittings and the retro bulbs.

The choice therefore comes down to three measurements taken in your home: the base, the space available and access to charging. Once these points are noted, compare calmly with compare with classic bulbs, and for a low-voltage setup, look at 12V LED bulbs. Secure payment, tracked delivery, returns and Designix customer service accompany every order, from choosing the base to receiving the parcel.
