4W ES/E27 LED Filament Clear Candle Lamp Dimmable 2700K Warm White 470lm

We all have wondered: LED vs Halogen vs CFL: Which Light Bulb Is Best in 2026? So… which light bulbs should you actually be using now? If you’ve been looking at lighting recently, you’ve probably noticed there are still a few different types of bulbs around—LED, halogen, and CFL.It can get a bit confusing, especially if you’re replacing older bulbs or upgrading fittings. Some customers still come to us asking for halogen lamps, others have CFLs in place already, and most are somewhere in the middle of switching over to LED.So instead of overcomplicating it, here’s a straightforward breakdown of how they compare in 2026—and what actually makes sense to use now.LED Bulbs (what most people are using now)LED has basically taken over at this point—and for good reason.Most of the lighting we supply now is LED, whether that’s GU10 spotlights, LED strip lighting, panel lights, or decorative filament bulbs. It covers pretty much every type of fitting.The main thing with LED is efficiency. You’re getting the same level of light for a fraction of the power.For example, a 5W LED GU10 will give you a very similar output to an old 50W halogen spotlight. That’s a huge difference if you’ve got multiple fittings in a room.What people like about LED:Uses much less electricityLasts a long time (you’re not constantly changing bulbs)Comes in loads of styles now (warm white, cool white, filament, strips, etc.)Works across pretty much all modern fittingsWe’ve also seen a big increase in customers going for things like:LED strip lighting for kitchens and media wallsBlack or brass LED fittings for more modern interiorsDimmable LED lamps paired with the right dimmer modulesA couple of things to watch:Not all LEDs work perfectly with older dimmer switchesCheaper LEDs can sometimes have poor colour or flickerBuy LED Lamps at SparksHalogen Bulbs (on the way out)Halogen used to be the standard—especially for GU10 spotlights and downlights.A lot of homes and properties still have them installed, so we still get people looking to replace like-for-like. But realistically, halogen is on its way out.They’re just not efficient compared to LED, and they run hot—which isn’t ideal in modern fittings.The good:Nice warm lightCheap to buy (initially)Simple replacement if you’ve already got themThe downsides:High energy usageMuch shorter lifespanGenerates a lot of heatBecoming harder to find due to regulationsIf you’re still running halogen GU10s, it’s usually worth switching over to LED equivalents rather than replacing them directly.CFL Bulbs (the in-between stage)CFLs (those spiral “energy-saving” bulbs) were the step before LED became widely used.You’ll still find them in older table lamps, ceiling pendants, and some commercial settings—but they’ve mostly been overtaken now.What they did well:More efficient than halogenCheaper than early LEDsWhere they fall short:Take a few seconds to reach full brightnessBulkier design (doesn’t suit all fittings)Contain small amounts of mercuryDon’t last as long as LEDMost customers replacing CFLs now just move straight over to LED alternatives, especially with the wider range of E27, B22, and decorative LED lamps available.For most applications, we recommend switching to LED lamps in either E27 (Edison screw) or B22 (bayonet cap) fittings. Popular choices include standard GLS-style lamps for general use—such as 8–9W LED bulbs that replace traditional 60W lamps—as well as filament-style lamps for more decorative fittings. For more focused lighting, reflector-style E27 LED lamps are also available, offering the same directional output as older halogen lamps but with significantly lower energy consumption.LED vs Halogen vs CFL: Quick comparison (simple version)Why most people are switching to LEDThe biggest reason is just the running cost over time.It might not seem like much per bulb, but when you’ve got:6–10 spotlights in a kitchenMultiple roomsLights used daily…it adds up.Swapping older halogen lamps for LED equivalents can make a noticeable difference—not just in energy use, but also in how often you’re replacing bulbs.What should you actually use?In most cases, it’s pretty straightforward now:Go for LED if:You’re upgrading lightingYou’re replacing halogen or CFLYou want longer-lasting lampsYou’re installing new fittingsHalogen: Only really makes sense if you’re doing a direct replacement short-term—but even then, LED alternatives are usually available.CFL: If you’ve still got them, they’ll work—but it’s generally worth switching to LED when replacing.Final thoughts: LED vs Halogen vs CFL - which one?At this point, LED is the standard for a reason. It covers everything from basic lamps to more design-focused lighting like LED strips, feature lighting, and modern fittings.Halogen and CFL both had their place, but in 2026, they’re mostly being phased out or replaced as people upgrade.If you’re unsure what to switch to, it usually comes down to finding the right LED equivalent for your existing fitting—whether that’s a GU10 spotlight, a filament-style lamp, or something more decorative.If you’re upgrading or just replacing existing lamps, it’s worth going straight to LED—and choosing good quality versions for each fitting type. For bayonet cap (BC/B22) fittings, a reliable LED lamp will give you that familiar look but with far better efficiency and lifespan. The same goes for ES/E27 bulbs, where LED filament options are especially popular now—they keep that traditional style while using a fraction of the energy. For spotlight fittings, MR16 LED lamps are a solid upgrade from older halogen versions, offering much lower running costs and less heat, which is ideal for modern installations.As for CFLs, we’ve now completely moved away from stocking them. With LED offering better performance in every area—efficiency, lifespan, light quality, and design—there’s simply no real reason to keep using CFL technology. On top of that, CFL lamps contain small amounts of mercury and are being phased out across the UK, so focusing on LED allows us to offer a more future-proof and environmentally friendly range.Recommended E27 (ES) LED LampsEveryday all-rounder (most customers will buy this)8.5W Dimmable 2700K Warm White E27/ES LED GLS LampA solid general-purpose bulb, giving around a 60W equivalent output.
