To change a spotlight bulb, switch off the lighting circuit at the consumer unit and let the bulb cool. Release the spring clip or twist the bezel anticlockwise; if the fitting has neither, pull the whole downlight straight down with a suction cup. A GU10 then comes out with a quarter turn anticlockwise, an MR16 pulls straight out.
Many spotlights give you nothing to grip: no clip, no ring, just a smooth disc flush with the ceiling. A screwdriver used as a lever tears the paper face of the plasterboard long before it frees the light. Here is how to tell which spotlight you have, how to get it out from below without damage, and which bulb to put back, because the bulb, not the fitting, decides the light in the room.
Which spotlight have you got? Four fittings, four ways in
Thirty seconds with a torch held at an angle to the ceiling are enough to tell which one you have.
| What you see | How to recognise it | How you reach the bulb |
|---|---|---|
| Spring clip, also called a circlip or retaining clip | A thin wire ring just inside the trim, in front of the bulb, its two ends bent into small loops | Pinch the loops together, lift the clip out of its groove, and the bulb drops into your hand |
| Twist-lock bezel | The front ring and the glass move as one piece, often with a ridged edge; common on fire-rated and bathroom downlights | Turn the bezel a short way anticlockwise and it comes down with the bulb inside it |
| Fixed trim, no clip or spring | A smooth disc flush with the ceiling, no ring, no slot, sometimes a soft seal round the edge | Nothing opens from below: the whole downlight comes out, held by two springs above the plasterboard |
| Sealed integrated LED | A frosted plastic face, no removable glass, a wattage on the label but no cap such as GU10 | There is no bulb: the whole fitting is replaced |
An eyeball or tilt spotlight is a variant of the first three, with a head that swivels in a gimbal. Bring it back level before anything else: a tilted trim jams in its hole, and forcing it is how the pivot snaps. For new lights rather than a repair, our guide to downlights covers the choice of fitting, the fire rating and the layout.
Switch off at the consumer unit, and let it cool
The wall switch is not enough: it may break only one conductor, and a downlight out of its hole puts your fingers millimetres from its terminals.
Switch off the lighting circuit at the consumer unit. Turn off the MCB, the circuit breaker for the lights, or take out the fuse carrier on an older fuse board, and expect more than one room to go dark. Tape over the MCB, or pocket the fuse carrier, and tell the household.
Prove it dead when the fitting comes down. A bulb behind a clip exposes no wiring; a downlight pulled out of the ceiling does. Test at the fitting with a two-pole voltage indicator checked on a known live source before and after use, the safe isolation routine the Health and Safety Executive describes. A silent non-contact pen is not proof.
Give it ten to fifteen minutes. A 50 W halogen GU10 and its reflector stay hot long after they go out, and even an LED has an aluminium heat sink that stays warm. Use a stable stepladder and a head torch, as in our guide on how to install a ceiling light.
One rule holds for the rest of the job: never leave a downlight hanging by its cable, which pulls on terminals never meant to carry it. Rest it on the stepladder tray or keep it in your hand.
How to change a spotlight bulb with no clip or spring
No clip and no spring covers two situations. Either the bulb sits flush and gives you nothing to hold, or the fitting has no opening at the front and comes down whole. If you can touch the glass of the bulb inside an open trim, it is the first; if a smooth cover hides everything, the second.
When the bulb has nothing to grip. Press a small suction cup onto the centre of the glass, push gently upwards and turn a quarter turn anticlockwise: a GU10 unlocks and comes out on the cup. A rubber glove gives the same grip on a clean glass face, and a tab of gaffer tape works on a frosted or ribbed LED front, where a cup will not hold.
When the whole fitting has to come down. The downlight is held by two springs above the plasterboard, which fold back on their own as the body comes down. Pull it straight down, and only straight down.
Suction cup, or tape. A glazier’s suction cup or a small one sold for phone screens, 3 to 5 cm across, goes in the centre of a clean, smooth, cool face. On a domed or textured diffuser, where a cup will not hold, stick two strips of gaffer tape across the trim in a cross and fold the ends back on each other into a soft handle.
Cut the paint seal. When the ceiling was painted after the downlight went in, a line of paint glues the trim to the plasterboard. Run a craft knife round it, blade flat against the ceiling, or the fitting takes a ring of paint and skim with it.
Pull straight, steadily. A firm, even pull in line with the hole, never a screwdriver levered against the plasterboard: the plaster always gives before the spring, and the hole ends up too big for the trim.
Take over by hand. Once the fitting is a centimetre down, slip two fingers behind the trim and guide it out. Hold the springs as they come through: released, they snap back and can crack the edge of the hole or catch your fingers.
Three things above the ceiling can make it harder. Loft insulation settles over the fitting and holds it back: pull more slowly, turning the body a little. A fire-rated downlight has a deeper steel body, and an ordinary one may sit under a fire hood: pull dead straight, without twisting, and leave any hood in place. In a bathroom, a soft gasket runs round the trim: do not cut it, and check it reseats when you refit, or the IP rating on the box no longer holds. Finally, never push insulation back over a downlight unless its instructions say it may be covered.
GU10, MR16 or GX53: the right move for each cap
With the bulb in front of you, the cap decides the move.
GU10. Two short pins with small feet, 10 mm apart, running straight off the 230 V mains. Push the bulb gently into its holder, turn it a quarter turn anticlockwise and it comes free. To refit, line the pins up with the wide part of the slots, push and turn clockwise to the stop.
MR16, with a GU5.3 cap. Two thin round pins 5.33 mm apart, fed at 12 V by a transformer above the ceiling. It does not turn: pull it straight out, rocking it very slightly. The two caps are not interchangeable. When a 12 V halogen gives way to an LED, the transformer is often the weak point: one built for 35 or 50 W halogens can make a 4 W LED flicker or refuse to start, as our guide to flickering lights explains.
GX53. A flat puck with two pins 53 mm apart, locked by a quarter turn like a GU10, found in slim fittings where the void above the ceiling is shallow.
Two precautions apply to all three. Keep bare fingers off the glass of a halogen: grease from the skin creates a hot spot. And when the cap stays stuck or the contacts are black or brown, it is the holder that needs replacing, like for like, with the care set out in our guide on how to wire a lamp holder; in a downlight it is often a ceramic GU10 socket on a short flying lead.
Refitting is the same job in reverse: bulb in, springs folded up along the body, the downlight pushed home until the trim sits flat, where the springs open on their own.
Integrated LED downlights: you replace the fitting, not the bulb
In an integrated LED downlight, the diodes sit on a board fixed inside the body with their driver: there is nothing to unscrew. The label gives it away, with a wattage but never a cap.
The swap is still within reach. Above the ceiling you find a plug-in connector with two poles, or three with the earth, or a small terminal block. Unplug the old downlight, plug in the new one, refit. For the result to go unnoticed, four things must match:
- the cut-out, the diameter of the hole, measured in the ceiling rather than across the trim;
- the depth available above the plasterboard, given on every product sheet;
- the colour temperature of the neighbouring downlights, in kelvins;
- the rating: fire-rated where the old one was, and in a bathroom the IP rating its zone requires.
In England, replacing a downlight like for like on the same point is not notifiable under Part P of the Building Regulations, but the work must still meet BS 7671, the IET Wiring Regulations. A new light point, a new circuit or an alteration to a circuit in the zones around a bath or shower is notifiable: it goes to a registered electrician on a competent person scheme such as NICEIC or NAPIT, or to building control before work starts. Wales has similar rules, while Scotland and Northern Ireland have their own. With a terminal block rather than a plug, or any doubt about proving the circuit dead, call a registered electrician.
When the old model no longer exists and the new one does not cover the hole, a wider trim or a conversion plate hides the difference. Or you give up on recessed lights: a surface spotlight fixes to an existing light point without cutting the plasterboard or disturbing the insulation, and takes GU10 bulbs you change in thirty seconds. Our spot ceiling lights run from single tubes to bars of two to six heads.
The bulb you put back decides the light in the room
A spotlight does not light a room, it lights a cone, and two bulbs with the same lumens, wattage and cap can open very different cones.
The beam angle first. Under a 2.4 m ceiling, 1.5 m above a kitchen worktop, a 24° beam draws a pool of light 64 cm wide, a 36° beam 97 cm, a 60° beam 1.73 m and a 90° beam 3 m. The same light spread over a larger area falls roughly in proportion at the centre: taking the 24° as the reference, the 36° keeps 43 per cent, the 60° 14 per cent and the 90° barely 5 per cent. Swapping a 36° bulb for a 60° one because it was the only one on the shelf cuts the light on the worktop by about two thirds. Our rule of thumb: a narrow beam to pick things out, a wide beam to light the room. For paintings, licht.de, the German lighting information centre, gives 10 to 30° for small pictures and 30 to 60° for large ones. In Great Britain, the beam angle of a spotlight has to be shown on the bulb itself where there is room, next to its lumens and colour temperature: read it on the old one before you shop.
The colour temperature next. In a row of spotlights, one bulb with a different tint shows at once, because the eye compares two pools side by side on the same surface. Read the kelvin figure on the old bulb, or on a neighbour that still works, and stick to it: 2,700 K in a living room, 3,000 K in a hall, 4,000 K over a worktop. Our guide to cool white vs warm white sets out the choice room by room. For the colour rendering index, our advice is 80 at least, and 90 or more in a kitchen or a bathroom, where you judge colours.
The dimmer last. On a dimmed circuit the new bulb must be dimmable too. The surest answer is the Dimmable line of the product information sheet, which can only read yes, only with specific dimmers, or no; our guide to the dimmable meaning shows where to find it. One unsuitable bulb can make the whole row flicker, and a dimmer built for halogen may not even see a few watts of LED. It catches out mood lighting most of all, where each source runs on two or three watts.
Our advice to finish: write in pencil on the body of the fitting, or inside the bezel, the cap, lumens, beam angle and kelvins of the bulb you have just fitted. Next time, you will know exactly what to buy.
Bathroom spotlights: the cover glass, the seal and the zones
Spotlights over a bath or a shower are usually sealed, often IP65, with a glass cover plate held by a twist-off bezel. Support the glass with your palm, turn the bezel anticlockwise and keep the gasket clean and whole. Refit the glass squarely: a cover sitting at an angle lets steam in, and condensation soon collects behind it.
BS 7671, the IET Wiring Regulations, divides a bathroom into zones around the bath and shower, and each zone limits the type of fitting and the minimum IP rating allowed. So put back exactly the same type of bulb, and for a whole new downlight choose one rated for that zone, confirmed by your electrician. Should the power trip when you switch back on, leave it off and call a registered electrician. Our guide to bathroom lighting explains the zones and which fitting can go where.
How to change a spotlight bulb: your questions answered
How do I pop out a spotlight?
When no ring or bezel comes off, two springs above the ceiling hold the downlight. With the circuit off at the consumer unit and the fitting cool, press a suction cup onto the centre of the face, or a cross of gaffer tape folded into a handle, and pull straight down without jerking. Hold the springs as they come through, and never lever with a screwdriver against the plasterboard.
How do you change a spotlight bulb with no spring?
Look at the edge first. When the front ring and the glass turn together, it is a twist-lock bezel: turn it anticlockwise and it comes down with the bulb. A flush bulb with nothing to grip comes out on a suction cup, pushed gently up and turned a quarter turn anticlockwise. When nothing moves at all, the springs are above the ceiling and the whole fitting comes down.
How do you change a 2 pin halogen bulb?
It depends on the pins. Thin round pins mean an MR16 on 12 V: pull it straight out, rocking it slightly, and push the new one straight in. Thicker pins ending in small feet mean a GU10 on the 230 V mains: push it in, turn a quarter turn anticlockwise and pull. Keep bare fingers off the glass of a new halogen, and when moving to LED on 12 V, check the transformer.
Do you need an electrician to change a spotlight?
Not to change the bulb: that is maintenance, done with the circuit off at the consumer unit. In England, replacing a downlight like for like on the same point is not notifiable under Part P, but it must meet BS 7671. A new light point, a new circuit or any alteration to a circuit in the zones around a bath or shower is notifiable, and goes to a registered electrician.
How do I change the bulb in my LED downlight?
A label with a wattage but no cap such as GU10 means there is no bulb: the LEDs are built in. Switch off at the consumer unit, prove the circuit dead, pull the downlight down and unplug its connector, then plug in a new one with the same cut-out, depth and colour temperature as its neighbours, fire-rated where the old one was. A terminal block instead of a plug is a job for a registered electrician.
What can I do if a spotlight bulb won’t come out?
Push before you turn: a GU10 only unlocks when pressed into its holder and turned anticlockwise. A suction cup or a rubber glove gives grip on a flush bulb, and an MR16 never turns, it only pulls. A bulb stuck fast or a scorched holder is a sign to stop forcing the glass, which can break and leave the cap behind: switch off, take the fitting down and replace the holder like for like.
