LED Bulbs price comparison UK
Switching to LED is no longer a question — it's the baseline. What's actually worth thinking about is which LED bulb, because the gap between a bargain and a genuinely good purchase is wider than most people expect. Our catalogue covers 909 products, with prices ranging from 4 £ all the way up to 13 £ for specialist or decorative options. The sweet spot for most households sits well below the median, which tells you something useful: overspending is easy, and unnecessary.
Paulmann dominates the catalogue by sheer volume, with nearly 350 references at a competitive average price — making it the go-to for anyone fitting out multiple rooms at once. Philips (across both its standard and Signify-branded lines) commands a premium, and in most cases it's justified: the Philips CorePro range consistently delivers reliable colour rendering and long lifespan. Osram sits in the middle ground — solid everyday performance, with its Vintage 1906 line offering a genuinely attractive filament aesthetic for living rooms and dining spaces.
Colour temperature is the single most misunderstood spec in this category. A 2700K warm white transforms a bedroom; the same fitting with a 4000K cool white bulb feels like a hospital corridor. Most of the top-selling products here sit in the 2000–2700K range, which reflects how British buyers actually use their homes. For kitchens, home offices, or utility rooms, 4000K is worth considering — but it's rarely the right call for living areas.
One thing our price data makes clear: the difference between the cheapest and most expensive bulbs in a given fitting type (say, GU10 or E27) can be tenfold. That gap isn't always about quality — sometimes it's purely about branding or packaging. Comparing prices across retailers like Currys, Amazon.co.uk, and specialist lighting suppliers before buying is genuinely worthwhile, especially if you're replacing bulbs in bulk. You can also explore halogen alternatives if you're working with older fittings, though LED remains the more energy-efficient and cost-effective choice in virtually every scenario.
How to Choose the Right LED Bulb
With 909 LED bulbs in our catalogue, the choice can feel overwhelming — but most buying decisions come down to four things: fitting type, colour temperature, brightness, and whether you need dimming. Get those right and the rest is largely about budget. Here's how to think through each one.
Fitting type (base/socket)
This is non-negotiable — get it wrong and the bulb simply won't fit. The most common in UK homes are E27 (large Edison screw, standard lamps and pendants), E14 (small screw, chandeliers and wall lights), GU10 (push-and-twist, recessed downlights), and B22 (bayonet cap, older British fittings). Low-voltage spotlights often use GU5.3 (MR16), which requires a 12V transformer — check whether yours is compatible before buying. If you're unsure, pull out an old bulb and look at the base: the code is usually printed on it.
Colour temperature: warm vs. cool
Measured in Kelvin (K), this determines whether your room feels cosy or clinical. 2000–2700K (warm white to warm comfort) suits living rooms, bedrooms, and dining areas — the majority of top-selling bulbs in this catalogue sit here for good reason. 3000K is a neutral warm that works well in kitchens. 4000K+ (cool white) is best reserved for task lighting: home offices, garages, utility rooms. Avoid cool white in spaces where you relax — it actively disrupts sleep and makes rooms feel unwelcoming.
Brightness in lumens, not watts
Watts measure energy consumption, not brightness — a common source of confusion when switching from incandescent. For a standard living room lamp, aim for 600–800 lumens. A bedside light can get away with 250–400 lumens. Recessed GU10 downlights typically need 400–600 lumens each. As a rough guide: a 7W LED produces roughly the same light as a 60W incandescent. Don't buy by wattage alone — always check the lumen output on the packaging or product listing.
Dimmability — check before you buy
Not all LED bulbs work with dimmer switches, and using a non-dimmable bulb on a dimmer circuit causes flickering, buzzing, or early failure. If you have dimmers, look explicitly for "dimmable" in the product spec, and ideally check that it's compatible with your dimmer brand (Varilight, Lutron, and Legrand are common in the UK). Some budget dimmable LEDs only work smoothly with specific trailing-edge dimmers — worth checking reviews before committing to a multipack.
Lifespan and total cost of ownership
The sticker price of a bulb tells you very little about its real cost. A bulb rated at 25,000 hours running 8 hours a day lasts roughly 8–9 years before needing replacement. At current UK electricity rates, a 7W LED costs around £1–2 per year to run — versus £7–10 for an equivalent halogen. Philips and Osram tend to back their lifespan claims more reliably than no-name alternatives. If you're buying for a rental property or a hard-to-reach fitting, spending a little more on a reputable brand pays off.
Decorative vs. functional: form factor matters
For exposed bulbs in pendant lights or vintage-style fittings, the shape and filament appearance matter as much as the specs. Osram's Vintage 1906 range and EGLO's globe (G-shape) bulbs are designed to be seen — they emit a warm 2000–2200K glow that mimics Edison-style incandescents convincingly. For enclosed fittings or recessed downlights, aesthetics are irrelevant and you should focus purely on lumens, beam angle, and efficiency. Mixing decorative and functional bulbs in the same room rarely works well.
- Budget picks (From 4 £ to 4 £) : Covers basic E27 and GU10 bulbs from Philips CorePro, EGLO, and Osram's standard lines. Perfectly adequate for utility rooms, hallways, or anywhere you need reliable light without caring about aesthetics. Don't expect long lifespan guarantees or dimmability at this end.
- The sweet spot (From 4 £ to 5 £) : Where most buyers should be shopping. Osram Vintage 1906, Philips CorePro multipacks, and mid-range Paulmann options all sit here. You get decent CRI, reliable dimming compatibility, and manufacturer lifespan ratings you can actually trust.
- For the discerning buyer (From 5 £ to 13 £) : Philips MASTER LED, LEDVANCE smart-ready options, and premium decorative bulbs. Justified for living rooms, dining areas, or anywhere lighting quality genuinely matters. The Philips MASTER range in particular is a step up in colour rendering and dimming smoothness.
- Specialist and premium (Over 13 £) : High-CRI studio bulbs, smart RGB options, and specialist fittings (Silver Electronics, premium Paulmann). Overkill for most homes, but worthwhile for home studios, retail displays, or smart home setups where tunable white or colour-changing capability is the point.

Frequently Asked Questions
What's the difference between E27 and GU10 bulbs?
E27 is a screw-fit base; GU10 is a push-and-twist pin fitting — they are physically incompatible and cannot be swapped. E27 is the large Edison screw used in most standard lamps, pendants, and table lights. GU10 is found almost exclusively in recessed ceiling downlights and some track lighting. Check your existing fitting before ordering: pulling out the old bulb and looking at the base takes ten seconds and saves a wasted return.
Can I use any LED bulb with a dimmer switch?
No — only bulbs explicitly labelled "dimmable" should be used with dimmer switches. Fitting a non-dimmable LED to a dimmer circuit typically causes flickering, buzzing, or premature failure. Even among dimmable LEDs, compatibility varies: some work best with trailing-edge dimmers (common in modern UK installations), while others suit leading-edge types. If you're replacing multiple bulbs on a dimmer circuit, check the dimmer manufacturer's compatibility list — Varilight and Lutron both publish these online.
Is a higher wattage LED always brighter?
Not necessarily — brightness is measured in lumens, not watts. Wattage tells you how much energy a bulb consumes, not how much light it produces. A well-engineered 7W LED can outshine a poorly designed 9W one. Always check the lumen output: 600–800 lumens suits a standard room lamp, while 400–500 lumens is enough for a bedside light. The efficiency rating (lumens per watt) is the most useful single number when comparing bulbs.
What colour temperature should I choose for a living room?
2700K (warm white) is the standard recommendation for living rooms, and it's what the majority of top-selling bulbs in this catalogue are rated at. If you want an even cosier, more candlelit feel — common in dining rooms or bedrooms — go for 2200K or 2400K. Avoid anything above 3000K in relaxation spaces: cool white light suppresses melatonin and makes rooms feel clinical rather than comfortable.
Are cheap LED bulbs worth buying, or should I avoid them?
Very cheap, unbranded LEDs are often a false economy — they tend to fail earlier, flicker more, and have poor colour rendering that makes rooms look flat. That said, budget options from established brands like Philips CorePro or Osram's standard range (available from 4 £) are genuinely good value. The risk is with unknown brands: they may not meet UK safety standards (look for the UKCA mark) and their stated lifespan figures are frequently optimistic. For a rental property or a hard-to-reach fitting, spending a little more on a known brand is worth it.
Do LED bulbs work in enclosed light fittings?
Not all LED bulbs are rated for enclosed fittings — check the product spec before buying. Heat build-up inside a sealed fixture can dramatically shorten LED lifespan and, in rare cases, pose a safety risk. Bulbs rated for enclosed use will state this explicitly. EGLO and Philips both clearly mark compatibility on their product listings. If in doubt, opt for a bulb with a lower wattage (and therefore less heat output) or choose one specifically designed for recessed or enclosed use.
How much can I actually save by switching from halogen to LED in 2026?
Switching a single GU10 halogen (50W) to an equivalent LED (5–7W) saves roughly £5–8 per bulb per year at current UK electricity rates, assuming average usage. Across a typical home with 10–15 downlights, that's a meaningful annual saving — and LED bulbs last 15–25 times longer than halogens, so replacement costs drop sharply too. The payback period on even a mid-range LED is usually under a year. You can compare halogen bulb prices alongside LEDs to see the full picture.
