Meet the best smart lights with Alexa and Apple HomeKit support, from Philips Hue, Lifx, Ikea and more

best smart bulbs 2021 and best smart lights

The best smart bulbs of 2021 are more than just light bulbs. They're mood enhancers, setting the tone in your room to match exactly how you want to feel - even if you're in the mood to bask beneath a bright green glow. Smart bulbs are great for evenings, dimming down low to help your mind unwind; they're equally adept and going bright and blue-ish, the perfect kind of lighting to enhance your focus while you're working. 

And, yes, the best smart bulbs are truly smart. They give you the chance to build automation and integration into your enhanced lighting experience, tying together bulbs which otherwise wouldn't be linked and allowing you to control them in a smart way. That might mean addressing them via Alexa or the Google Assistant, it might mean dropping Zigbee-compatible bulbs into the Hue ecosystem, it might mean setting schedules – whichever way you play it, a smart bulb is a great thing.

This list is here to cover everything that's good in the smart bulb world. Your mind might initially jump to big brands like Hue and LIFX, and they're definitely here, but there are also some can't-miss examples from companies such as Ikea, newer brands breaking out such as Innr, bulbs from known smart-home experts like TP-Link, and more unconventional lighting from the likes of Nanoleaf – plus many more.

As with any other gadget, it pays to do your research (that's why you're here, we'd wager) so let's look at the aspects that are going to be most important when you're deciding which is the best smart bulb for your home.

Smart lighting and smart bulb considerations

Smart lights might be relatively simple things, easy to understand and perhaps even easier to set up, but they do have the ability to make a big difference to your life. Our top pick, at this point, is the Philips Hue range; they're not the cheapest on the market (though many Hue-compatible bulbs do come in at a lower cost) but the vast number of different smart bulbs available, from drop-in replacements for your ceiling lights to outdoor lamps, light strips and beyond, makes it the ecosystem of choice.

We might love it, but that doesn't necessarily mean you should go Hue. There's a wide range of kit out there; perhaps the hub-free nature and bombastic bulbs of, say, LIFX, might suit you better. Maybe you're interested in trying the up-and-coming Thread protocol with Nanoleaf's fresh Essentials range. Perhaps you want to save a buck with one of the many budget brands. Let's take a look at how you should decide on the right smart light ecosystem for you.

How to buy the best smart bulb for you

Ikea Tradfri best smart bulbs 2021

Smart bulbs are a great way to dip a toe into the smart home waters: they may not change your life overnight, but they're definitely fun little devices that you can tinker around with. They'll undoubtedly impress guests, and can prove surprisingly useful too (maybe you could have the kitchen light up whenever someone walks in).

If you've got some smart home kit already, get smart bulbs which play nice with everything else you own – the main ecosystems to look out for are Apple Homekit, Amazon Alexa, Google Assistant, and Samsung SmartThings, and the larger brands (like Philips Hue and Lifx) tend to offer good compatibility across the board.

Those of you who aren't so interested in building out a wider smart home ecosystem can go for cheaper options such as the Ikea Trådfri system – these bulbs have their own app and remote, but don't fit in with wider ecosystems quite as well.

You also need to decide whether you want smart bulbs best for cycling through all the colours of the rainbow, or just tuneable white bulbs, able to emit blue-ish whites or yellow-ish whites depending on your needs. Colour-changing bulbs look fancier, but these sort of white bulbs are arguably more useful (and cheaper as well).

A bulb's lumen rating (how bright it is) is important to consider, and you also need to make sure you buy a bulb which fits your lamp socket. Most smart bulbs feature an E27 screw fixing, but some manufacturers such as Philips and Osram offer a wide variety of fixings, including bayonet, GU10, and more, so it's always worth checking.

The best smart bulbs available in 2021: get the best smart lights for you

Philips Hue bulbs best smart bulbs and best smart lights


1. Philips Hue

Our T3 Awards 2020 Smart Lighting winner – and the best smart bulbs you can get

Reasons to buy
+Broad compatibility+Responsive in operation+Huge range of bulbs and light fittings

Hue is so well established in the smart lighting world that it has almost become a genericised trademark, but there's more to its success than simple brand recognition. Hue lights top our list because they're just so good, and so varied, that every other brand (even LIFX, below) is playing catchup. 

The bulbs themselves use Zigbee to communicate, meaning you'll either need a Hue Bridge to talk to them, or a generic Zigbee hub, the likes of which you'll find in the Amazon Echo 4th Generation. Zigbee's great advantage is that it can reach a long way - it's a mesh network, and each bulb can act as a repeater which invisibly passes signals along to the next in line. This means you can take Hue further than your router would generally reach, making it more than plausible to get started with the Philips' vast outdoor range as well as its huge number of options for indoor lighting.

If you're really stuck, Hue also includes a Bluetooth radio in all of its newer bulbs, so you can connect and switch them on or off locally, though this is significantly less convenient.

Whichever part of its range you exploit, Hue tends to be brighter than its competitors, and very accurate in terms of colour reproduction. We'd suggest beginning with a Hue starter kit, which will pack in a few bulbs, that Hue Bridge, and perhaps a discrete remote control too. 

Each Hue Bridge can support up to 50 connected lights, from Hue or any other Zigbee-compatible range, so there's plenty of room to expand. You'll be able to access and control them through every major smart assistant. This includes Siri, as the Bridge has full HomeKit support; we should note that you may not get the same level of control if you're connecting them to a third-party hub. 

Basically, they're brilliant. Hue deserves to be your first choice if you're looking for the best smart bulbs for starting a smart lighting system. Yes, the requirement for a hub is awkward, but you'll get over it. They might not have the wacky effects of LIFX, but that's a style point that can't take away from Hue's substance. 

Because of the huge range of indoor and outdoor lighting types Philips offers, it's hard for us to point you to the exact bulb type you need for your house, so here's where you can find great prices on the Hue ranges:

Lifx bulbs best smart bulbs and best smart lights


2. LIFX

A worthy Hue competitor, LIFX smart bulbs deliver excellent smart lighting

Reasons to buy
+A breeze to use+Wide selection+Reliable operation

There are two schools of thought in the smart bulb world. Some feel the best path is to opt for bridged lights, which (in the case of those which are Zigbee compatible, like Hue) form their own little mesh network, passing on activation commands and colour changes that way. Others would rather Wi-fi did the heavy lifting - and that, along with their elegant design, is the key selling point of LIFX bulbs.

These link straight to your existing wireless network, with no additional hub required. This does simplify things somewhat, but it adds to the per-bulb cost, so if you're planning to deploy a large smart bulb network, you may find Hue (or similar) to be more cost effective overall.

They're really very good as smart bulbs, nailing the colour aspect perfectly, responding well to commands, and tying in neatly to your choice of smart assistant. The app offers one-touch control of your connected lights, and some very detailed control deeper down, and everything's easy to set up and get running.

There's more than just the standard LIFX and LIFX Mini bulbs, too: look to the Plus range if you want a bulb which is going to work well with your smart security cameras, as they include infra-red LEDs which stay on even when you've turned the main lighting off; check out the likes of the Beam and Z Strip for feature lighting with more smarts and funky effects than most.

Best smart bulbs - Nanoleaf Essentials

3. Nanoleaf Essentials

Essentially some great little cheap bulbs and light strips

Reasons to buy
+Good price+Thread compatibility+Excellent app

Here's an odd move, but a welcome one, from perennial shapes-on-your-wall supplier Nanoleaf: a set of bargain-priced smart bulbs and light strips to give you control of more than just those pretty wall decorations. 

Probably the most interesting thing about the Essentials line, beyond its price, is support for Thread, a smart home protocol that's just now starting to emerge. Thread works in much the same way as the Zigbee of bulbs like those of Hue, giving the Essentials bulbs mesh networking capabilities. While you can address them without a hub, they are compatible with the Thread hubs in devices like the Nest Wifi and Apple Homepod mini, which offers a management advantage.

They're elegantly designed. We love the way the RGB bulbs look at least, even if the extendable light strips are pretty standard-looking, and you can rely on Nanoleaf's well-matured app to give you a good range of control options. One to sample, we'd say, and at the price you're not going to miss out on much if they don't meet your needs.

Ikea Trådfri bulbs best smart bulbs and best smart lights


4. Ikea Trådfri

Smart lights with your furniture, and one of the best smart bulb ranges going

Reasons to buy
+Simple to use+A choice of fittings+Very affordable

If you've taken a wander around Ikea lately, you've probably noticed the Trådfri smart lights that have started popping up – they're a cheap, accessible way to get started in your best smart bulb search, though you don't get as many features as you do with products from the likes of Philips Hue and LIFX.

Both white light and coloured options are available in E14 and E27 sizes, though you only get screw rather than bayonet fittings. Spot lights and panel lights are available too.

We've added the Trådfri range to our best smart bulbs 2021 list because you get useful, straightforward functionality with no gimmicks – and because they're made by Ikea, the price is very appealing too. We're assuming that Ikea will continue to add to the range over time.

You do need a separate gateway or remote device to connect to your router for the advanced features (such as controlling whole groups of lights), but there is now support for Amazon Alexa, Google Assistant and Apple HomeKit, making them simple to integrate into an existing system. Much like Philips Hue, here are other useful smart home accessories in the Trådfri range that supplement the bulbs, such as smart plugs and smart light switches. 

Even more interesting is that there are light panels that can be built into Ikea furniture, again fully controlled via the smart system – this is a really clever and unique touch. See the full range of Trådfri options below.

TP-Link Kasa KL130


(Image credit: TP-Link)

Google Assistant, Amazon Alexa and IFTTT smart bulbs for an attractive price

Reasons to buy
+Simple to operate+Don't cost too much+Works with Google/Alexa

TP-Link has a more limited range of products compared to Philips Hue, and you can't do quite as much with these bulbs, but we've taken quite a shine to the TP-Link Kasa bulbs nevertheless (pun actually intended). They're cheap and you can get them up and running very easily, without having to buy a separate gateway or hub. And the major bulb types are covered, of course, so there'll still be something great here for most people. 

Affordable and reliable is usually the theme with TP-Link kit. The manufacturer has a strong track record in networking and smart home gear, especially in this Kasa range, so you can buy safe in the knowledge that these bulbs are going to last, even if they don't have as many features as some rivals. They have a few different lighting options to check out, including the TP-Link Kasa Smart Light Strip (KL430) so be sure to check out that review. 

Even better, these smart bulbs can work with Google Assistant, Amazon Alexa and IFTTT, so there's plenty of opportunity for integrating them in with the rest of your smart home. They don't work with Apple HomeKit though, sadly. If you just need one or two basic lights to hook up directly to your Wi-Fi router then these are definitely worth considering as the best smart bulbs for you.

TP-Link seems committed to adding new products over time too and considering it also puts out smart plugs and other bits and pieces, we don't think you're going to find these products abandoned anytime soon. Well worth a spot on our best smart bulbs 2020 list.

Best smart bulb Nanoleaf

6. Nanoleaf Light Panels

A smart lighting system with a difference

Reasons to buy
+Will definitely impress the guests+All kinds of permutations possible

After something a little bit different in your search for the best smart bulbs of 2020? Nanoleaf's approach might be just what you're after: flat panels that tessellate to create walls of coloured light that you can graduate across your designs, and that can even pulse along with music.

The panels can be adhered easily to walls or the ceiling, and besides the music trick they can be set to run on a schedule, controlled manually from your phone, or even used as alarms to wake you up in the morning.

Everything works with Amazon Alexa, Google Assistant and Apple HomeKit as well, so it's easy enough to combine the Nanoleaf range with whatever else you've got happening in your smart home. You can easily expand beyond the nine panels you get with the starter kit to cover a whole room if you want – and while we've pictured the triangular starter pack above, there are also square panels with their own starter kit, and hexagonal panels are just arriving too.

These smart lights aren't for everyone – just looking at the product picture should be enough to tell you if these are the best smart bulbs for you – but there's no doubt that they definitely stand out from the crowd and let you create some amazing ambiance.

Eufy Lumos Smart Bulb best smart bulbs 2020

7. Eufy Lumos Smart Bulb

Start with the basics of smart lighting

Reasons to buy
+Straightforward setup and use+Works with Amazon Alexa+Auto-schedule feature

Eufy is better known for its cleaning gadgets and is just getting started in the smart lighting market – so there's just one white bulb to pick from here – but the Lumos Smart Bulb is definitely worth a mention in our list.

It's simple to operate, the app is nice and polished, and you can control your Eufy Lumos bulbs with an Amazon Alexa command too. If you want, you can have your lights come on via a schedule, or switch on and off randomly to try and trick burglars into thinking someone's at home.

Eufy doesn't offer any coloured bulbs yet, but kit your house out with these and you've still got plenty of functionality to play around with – dimming, brightening, scheduling and so on.

These lights work without any kind of hub plugged into your router too, connecting directly like the Lifx bulbs, so you can easily add one or two to your home without spending too much. If you decide you want to switch to something else, you're not so much out of pocket as you might be with other systems.

Hive Active Lights best smart bulbs 2020


8. Hive Active Lights

The best smart bulbs for your Hive smart home system

Reasons to buy
+Different bulb types available+Simple to set up and operate+Works with a range of other kit

Hive started out with a smart thermostat but has since expanded its range to include just about everything you might need for your smart home. The smart bulbs that Hive puts out are very capable and attractively placed, and well worth a spot on our best smart bulbs of 2020 list.

You can pick from standard bulbs (screw or bayonet), E14 candle bulbs, and GU10 spotlights, and the standard bulbs offer the full colour spectrum as well as different white temperatures. The range isn't quite as big as those offered by Philips and Lifx, but it'll be enough for most people.

As with Philips Hue, you need a hub attached to your router to use these lights (unless you hook them up to a Samsung SmartThings network instead). Within the app, you get colour changing and schedule setting features, and the smart bulbs work with both Amazon Alexa and Google Assistant.

If you already have Hive kit in your home then it makes sense to go for the bulbs as well, as everything is going to work seamlessly together.

Innr smart lights

9. Innr

Up and coming smart bulb ecosystem

Reasons to buy
+Can work with several bridges+Plenty of bulbs to pick from+Very simple app and operation

Innr is a newer name in the smart lighting market but it's already attracting a lot of attention, with an impressively large range of bulbs to pick from that are simple to set up and use.

This is a smart lighting system that you need a bridge for, but you don't necessarily have to use the Innr Bridge if you don't want to – the bridges for Philips Hue and Samsung SmartThings use the same kind of technology, so you can use them instead if that's more convenient.

You can pick from spot lights, standard bulbs, filament bulbs, candle bulbs, LED lights and more, both coloured and light (though there are no bayonet fitting options, just E14, E27 and GU 10 types).

While Innr might not topple Philips Hue or Lifx any time soon, and the app is a bit rough around the edges, we're impressed with the size of the range here, and the affordability of the prices. Definitely one to keep an eye on.

Osram Lightify best smart bulbs and best smart lights


10. Osram Lightify

From the people who do the lights for Eurovision!

Reasons to buy
+Plenty of options+Indoor and outdoor operation+Gateway is wireless

You might not have heard of them, but Osram is one of the leading manufacturers in the lighting industry – and they have been known to do the backdrops for Eurovision, so there you go. If you've ever thought your home could use a bit more Eurovision glitz and glamour, then you know where to come.

From simple white bulbs to multi-colour top-of-the-range lights, there are plenty of choices in the Osram range: this is a more comprehensive solution than the likes of Ikea and TP-Link can offer, and it takes a bit more effort to set up too, so bear that in mind in your search for the best smart bulbs.

You can really go to town if you want to, with LED strips and garden lights included in the range. For all of this to work you're also going to have to buy yourself a gateway device, though thankfully it doesn't need a wired connection to your router like the Philips Hue Bridge does – so that's one point in its favour.

If you're looking to give your whole home a smart lighting revamp then Osram is definitely one of the best smart lighting options out there, but for smaller-scale projects and simpler operation you might be better off looking elsewhere.

Sengled Element Starter Kit best smart bulbs 2020


11. Sengled Element

The best smart bulbs for a quick and cheap start

Reasons to buy
+Simple and affordable setup+Works with Alexa and Google Assistant+Software apps do the job

There are two main reasons to pick something from the Sengled Element range as one of the best smart bulbs for 2020 – their simplicity and their low price. If you want to save some money, give them a look as you browse through the various options.

Despite the low price you get plenty of functionality here, including lighting schedules, and support for Amazon Alexa and Google Assistant control. You do need to set up a central hub, but that hub can then control up to 64 bulbs.

Both white and coloured bulbs are available, in both screw and bayonet fittings, so you should be able to find something to suit your needs at home. The app is nicely polished and a breeze to use, which helps.

Other smart bulbs might come with a bigger brand name attached, and more features to play around with, but that shouldn't necessarily put you off.

Xiaomi Mi LED Smart Bulb best smart bulbs best smart light


12. Xiaomi Mi LED Smart Bulb

Affordable smart bulbs that connect direct to your Wi-Fi

Reasons to buy
+Attractive price+No separate hub required

The Xiaomi Mi LED Smart Bulbs have now launched in Europe and the low price makes them an attractive purchase if you want to add a few to your home and you're not already invested in a smart bulb ecosystem from a brand such as Philips Hue.

To use, simply screw the bulb in, pair it with the Mi Home app and then use the app to connect the bulb to your wireless network – there's no separate hub required. Now you can use the app to remotely turn the light on and off, change its colour and  brightness, or set it on a timer. You can also control the lights via Google Assistant, Amazon Alexa and Apple Home Kit.

As a basic remote-control light with adjustable colours, the Xiaomi Mi LED Smart Bulb is great for the price. It doesn't offer the range of options that you get from systems such as Philips Hue or Lifx but then it doesn't ask the higher price of those set-ups, either. It also only comes as an E27 fitting, so if you're after a B22 or GU10 bulbs, you'll need to look elsewhere.

Xiaomi now makes a whole host of different gadgets and electronics, and the bulbs are the same as the other kit that it makes: well built, maybe a bit rough around the edges in terms of style and app support, and very reliable and affordable.
