Mike's quick answer
For a new or renovated kitchen, go integrated: brighter per fitting, smoother dimming and every light the same colour. Go GU10 for a rental, a tight budget or smart bulbs.
If you’re redoing a kitchen or replacing old halogens, this is the first choice you’ll make: GU10 fittings with a bulb you can swap, or integrated LED downlights where the light is built in.
Both work. It comes down to how long the kitchen has to last, whether you want dimmers, and how much you care about every light matching.
Side by side
| GU10 | Integrated | |
|---|---|---|
| Typical output | 300–500 lm | 450–800 lm |
| Rated life | 15,000–25,000 h | 25,000–50,000 h |
| Cost per fitting | £8–£23 with bulb | £10–£60 |
| Dimming | Bulb and dimmer must match | Smooth to about 5% |
| Colour match | Can vary bulb to bulb | Same from fitting to fitting |
| Smart bulbs | Drop one in | Smart switch instead |
| When it fails | Swap the bulb in seconds | Replace the fitting |
Yellow = the better option on that line.
Brightness: fewer fittings, same light
A GU10 bulb usually gives 300 to 500 lumens. A typical integrated kitchen downlight gives 450 to 800. Because the LED, lens and driver are designed together, more of that light lands where you want it.
In practice, a kitchen that needs eight 400-lumen GU10s for even coverage can often get there with six integrated units of 550 to 600 lumens.
SaveSame kitchen, similar light on the worktops. An integrated fitting puts out more usable light, so you need fewer of them.
For an average UK kitchen, well-spaced GU10s are bright enough. The difference shows in bigger kitchens, open-plan rooms and kitchens with dark worktops or units that soak up light. To work out how much light your room needs, use the lumens guide, and for where the fittings go, see downlight spacing.
Colour: every light the same white
This is the one people notice once it’s been pointed out. A bulb labelled 3000K should be warm white, but one brand’s 3000K can look different from another’s, and even one brand can vary between batches.
In a ceiling of six or eight GU10s, one or two slightly warmer or cooler bulbs make the whole ceiling look patchy. The only fix is buying a full set from one batch.
Integrated fittings mostly avoid this: the LEDs come from the same production run and the lens is matched to them, so a row of six looks the same. In a modern kitchen with pale surfaces and clean lines, that matters. More on choosing the right white in the colour temperature guide.
Dimming is where you notice the difference
A GU10 bulb has to fit its driver inside a small bulb body. Cheap ones flicker at low levels, buzz, drop straight from dim to off, or dim at different rates from the bulb next to them.
Good GU10s from the big names (Philips, Osram, Megaman) dim reasonably well, but only with a compatible trailing-edge dimmer and enough load on the circuit. You end up matching bulb, dimmer and number of lights.
Integrated units have room for a proper driver designed for that LED, so quality ones dim smoothly to around 5%, some lower, without flicker. If you want bright light for cooking and a low glow for eating, that’s the difference you’ll feel every evening. Whichever you fit, use a trailing-edge (LED) dimmer. If yours already flicker, here’s how to fix it.
Lifespan, and what fails first
LED GU10s are usually rated for 15,000 to 25,000 hours. At five or six hours a day, that’s roughly seven to eleven years. Cheaper bulbs often fade or shift colour sooner.
Integrated fittings are usually rated for 25,000 to 50,000 hours, around 13 to 27 years at the same use. The heat sink is designed for that LED, so they tend to hold their brightness and colour for longer.
The catch is the driver. In a GU10 the driver is in the bulb, so a failure costs you a bulb. In an integrated fitting, a driver that fails early means a new fitting. Good brands rate the driver to last as long as the LED; cheap ones don’t always. That’s why the brand matters more with integrated.
Cost now and over ten years
| GU10 | Integrated | |
|---|---|---|
| Fitting | £5–£15 (fire-rated) | £10–£35 standard, £40–£60 premium |
| Bulb | £3–£8 | Built in |
| Per downlight | About £8–£23 | About £10–£60 |
For eight downlights, the gap at the budget end is small, perhaps £50 to £80 across the kitchen. At the premium end it’s more like £150 to £300.
Over ten to fifteen years it evens out. You’ll probably replace a set of GU10 bulbs once or twice, at £25 to £65 a time for eight, more if you upgrade to better bulbs to cure flicker. A good integrated fitting should need nothing in that time.
If the kitchen is meant to last ten years or more, integrated usually works out cheaper overall. For a rental or a stop-gap, GU10 is the cheaper start.
When a light fails
This is GU10’s strongest point. Twist the old bulb out, push a new one in: thirty seconds, no tools, no electrician. GU10 bulbs are sold everywhere.
A failed integrated fitting means disconnecting it in the ceiling and wiring in a new one. Some have plug-in connectors; others should be swapped by an electrician. And if the model is discontinued, matching the bezel, cut-out size and colour of the rest can be hard. Buy one or two spares when you fit them.
Fire rating and building regulations
Most kitchens need fire-rated downlights, whichever type you choose. Under Approved Document B of the Building Regulations, a downlight cut into a ceiling between two floors must not reduce that ceiling’s fire resistance. In a two-storey house, that’s almost every kitchen.
Both types come in 30- and 60-minute fire-rated versions, and there’s no real difference in fire performance between them. The mistake is buying cheap open-backed fittings. If insulation sits on top of the ceiling, look for fittings rated to be covered by it (often marked IC).
Looks: bezels and finishes
Integrated fittings can be shallower with a slimmer bezel, some only a few millimetres, so the fitting almost disappears. Trimless versions plaster in completely flush.
GU10 fittings need room for the bulb, so the bezel is usually bigger. That’s no bad thing in a traditional or cottage kitchen, where a chrome or brass ring looks right. In a minimal modern kitchen, integrated looks cleaner.
Smart lighting: GU10 is easier
Smart GU10 bulbs are everywhere: Philips Hue, WiZ, TP-Link Tapo, IKEA. Drop one into any fitting and you get app and voice control and adjustable white.
Smart integrated fittings exist but the choice is smaller. Many integrated units offer a switch on the fitting to pick 3000K, 4000K or 6500K before you install it. That’s handy if you’re unsure, but you can’t change it later without taking the fitting down.
With integrated fittings, a smart dimmer switch on the circuit is the cleaner route: app control, scenes and smooth group dimming, though not adjustable colour. More in smart kitchen lighting.
Fitting them
Both go in the same way: a hole in the ceiling (usually 65 to 85 mm), the wiring connected, and spring clips holding the fitting. Integrated units increasingly use plug-in connectors, which speeds things up.
New downlights where there were none (new holes, new cable, a new circuit) are a job for a registered electrician. Swapping GU10 bulbs is a DIY job; replacing integrated fittings that involve wiring is best left to a professional.
Which one for your kitchen
- New build or full renovation: integrated. You’re starting fresh, and you get the dimming, matching colour and slim look.
- Replacing old halogen GU10s: if the fittings are sound and in the right places, just swap to LED GU10 bulbs. If they’re tired or badly placed, it’s worth going integrated.
- Rental or short-term: GU10. Cheap, and tenants can change a bulb themselves.
- High-end kitchen with dimmers: integrated, without question.
- Smart home: GU10 with smart bulbs for full control, or integrated on a smart dimmer if you only need dimming and scenes.
- Tight budget, doing it yourself: GU10 now, smart bulbs later if you want them.
Can you mix them?
Yes, and it’s common. Use integrated for the main ceiling grid over the worktops, and GU10 bulbs in pendants, wall lights or track, where swapping bulbs and smart control are handy. Keep them on separate circuits.
What to avoid is mixing the two in the same row across a ceiling. The different bezels, beams and whites will show.
What I'd buy

Are GU10s being phased out?
No. GU10 is still one of the most common bulb types in the UK and LED versions are made everywhere. What’s changed is that integrated fittings are now the usual choice for new installations, so GU10 is mostly used for replacements.
Can I swap my GU10 fittings for integrated ones?
Yes, but it’s more than a bulb change. The old fitting comes out, the wiring is reconnected to the new one, and the cut-out size may differ (many GU10 fittings use 75 to 85 mm). Check the sizes before ordering, and use an electrician if you’re changing several.
Do I need fire-rated downlights in my kitchen?
If the ceiling has a room above it, yes, for both types. With only a loft above, fire-rated fittings are still good practice, especially if the loft is boarded. If you’re not sure, ask your electrician or building control.
Is high CRI worth paying for in a kitchen?
Yes. CRI is how true colours look under the light. Food, worktops and skin all look better at CRI 90 or above, while below 80 everything looks a bit washed out. Most good integrated fittings meet 90; GU10 bulbs vary, so check the box.
What beam angle should kitchen downlights have?
Around 55 to 60 degrees for general light across the room, and a narrower 36 to 40 degrees for focused light over worktops or an island. Some integrated fittings have swappable reflectors, which helps if you’re unsure.
