Best smart light 2021: Philips Hue, LIFX and others we've tested

The best smart light can make life easier by ensuring you can brighten, dim or even switch the light on or off from your smartphone, without having to leave the sofa. You can even change the color of a smart light bulb, ensuring you can create the perfect atmosphere any time of the day or night. 

The best smart light can also be a great way to save energy and money too. It replaces your existing light bulbs, but it's an LED bulb, they last longer than incandescent lights and use less energy too, making them great for the environment and your wallet. 

Some smart light bulbs use Bluetooth to connect to your smartphone, while more expensive versions rely on Wi-Fi, which means they can be controlled even when you’re not close by. No matter which style you opt for, smart lighting is one of the most affordable smart home devices on the market, making them good for those dipping their toe in the smart home world, as well as anyone that wants to expand their home automation without causing too much pain to their wallet. 

Smart lighting can also be used in home automations, for example ensuring they switch on at the same time as appliances connected to smart plugs, while your smart thermostat raises the temperature a few degrees to create a cozy setting when it's time for you to get in from work. You can also use a voice assistant in one of the best smart speakers or best smart displays to control your smart lights, rather than your smartphone. 

There’s plenty of choices when it comes to smart lights on the market right now, with brands such as Philips and LIFX nestling side by side with more affordable names including Eufy and TP-Link. This may leave you feeling bemused at which you should choose? To help you decide we’ve put an array of designs to the test to ensure you’re switched on to just which is the best smart light for 2021. 

The best smart light of 2021

Philip Hue white and color ambience bulbs on a white background

1. Philips Hue Color Ambience

The best smart light bulb you can buy

Wattage: 10 W | Color: +16 million colors | Color temperature: 2,000-6,500K | Lumen output: 806 | Lifetime: 25,000 hours | Height: 109.2mm | Diameter: 62mm

Easy to set up
Works with Alexa, Google Assistant, and HomeKit
Wide array of different smart lights
Hub needed to access all features
Expensive compared to incadescent bulbs

There's a very good reason why Philips Hue is the biggest name in the smart lighting scene: it's without a doubt one of the greatest offerings to the market. The lights produce the most natural tones of any smart lighting we've used, the app is easy to use, and installation is a doddle. 

There's a wide range of different smart lighting too; from color (with 16 million shades) and white bulbs (both solid and ambient that offers a host of different hues) to side and ceiling lamps, outdoor lighting, and even Philips Hue lightstrips. We were also impressed the smart lights work with Alexa, Google Assistant, and HomeKit. 

That said, while the newer version of Hue Bulbs have Bluetooth built-in so you don't need a hub to set them up, the Hue Bridge ensures you can access all of the handy features such as geofences and the ability to customize when lights come on; for example at a set time or when something happens ie sunset or sunrise.

2. LIFX A19

The best smart light bulb without a hub

Wattage: 11 W | Color: 16 million colors | Color temperature: 2,500-9,000K | Lumen output: 1100 | Lifetime: 25,000 hours | Height: 114.8mm | Diameter: 62mm

No hub required
Wide array of colors and styles
Works with Alexa, Google Assistant, and HomeKit
Bulky, unusual looking bulbs
Expensive compared to incandescent bulbs

Just like Philips Hue, LIFX offers a plethora of smart light options; from color and white bulbs, that come both in full size and the more compact LIFX Mini design, as well as lightstrips, LIFX Beam - the brands own take on smart light wall art and LIFX Clean - a smart light that can also kill bacteria. There's also an outdoor bulb that enhances the night vision of best home security cameras

Unlike Philips Hue, LIFX bulbs don't need a hub to access all of the features - these smart lights connect directly to your Wi-Fi.  Simple to set up and easy to control, we were I'm[pressed at the vibrant colors offered by the bulbs, too.  However, just like Philips Hue, the bulbs are expensive compared to incandescent bulbs. 

They're compatible with HomeKit, Amazon Alexa, and Google Assistant too, meaning no matter the type of smart home you have, they'll fit in. However, the bulbs have an unusual style with a flat top, so they don't look natural, and they're bulky too.

The Nanoleaf Shapes triangle light panels illuminate pink, orange and yellow on a white background

3. Nanoleaf Shapes

The best smart light to match your mood and music

Wattage: 42 W | Color: 16.7 million colors | Color temperature: 1200-6500K | Lumen output: between 20-100 LM/Panel | Lifetime: 25,000 hours | Height: 200mm | Width: 230mm

Easy to set up
Illuminated wall art rather than bulbs
Can change color and pulse to create fun effects
Difficult to remove once mounted
Don't look attractive when not illuminated

The Nanoleaf Shapes take the concept of lighting and turn it base-over-apex. Using a collection of hexagonal and triangular panels, you create a dynamic shape on your wall (or ceiling, or both) that can shift through over 16 million different colors. 

What's more, the panels can glow solid colors or can transition at different speeds through colors to create a unique lighting effect in your home. On top of that, you can set the panels to react to touch or even music playing in your surroundings, putting you in the centre of your own music video.

The original set comes with nine panels, all of which are the same shape, but you have the option to add more and you can mix and match the different shapes. We admit these plastic panels don't look particularly attractive when they're not illuminated, so if you're after a more stylish look at all times; Nanoleaf Elements in a version of the hexagonal panels that have a wood-like veneer on them. They're also difficult to remove once mounted, 

Don't like the sound of hexagons and triangles? Nanoleaf Canvas are square-shaped light panels but they can't be combined with Nanoleaf Shapes, unfortunately.

4. Nanoleaf Essentials

The best affordable smart light bulb

Wattage: 9 W | Color: 16.7 million | Color temperature: 2,700-6,500 | Lumen output: 1,100 | Lifetime: 25,000 hours | Height: 110mm | Width: 61mm

Affordable
Thread and Bluetooth connectivity
Circadian Lighting feature mimics natural light
Lacks Alexa integration
Unusual design

There's no denying the Nanoleaf Shapes create unique lighting effects, but they are an expensive purchase, and they won't fit existing side lamps. Fear not, Nanoleaf also offers the more affordable Essentials range of smart lighting. Choose between the smart light bulb, with a unique geometric design known as a rhombicosidodecahedron (although this won't be to everyone's taste), or the Nanoleaf Essentials lightstrip.

Not only can they glow a wide range of colors, they even have a Circadian Lighting feature that changes the color temperature throughout the day to mimic the natural light.  

Nanoleaf Essentials smart lights support Thread, a smart home technology, that is more stable than Wi-Fi and puts an end to laggy connections, as well as Bluetooth. However, they only work with HomeKit and Google Assistant, so it might be worth avoiding if you use Alexa to control your smart home.

The best smart light bulb for retro style

Wattage: 7 W | Color: Untunable | color temperature: 2700 | Lumen output: 800 | Lifetime: 20,000 hours | Height: 120mm | Width: 60mm

More affordable than most smart bulbs
Alexa and Google Assistant  support
Color, white or filament style offered
No HomeKit support

TP-Link may be a brand best well-known for networking products such as the best wireless routers and the best powerline adapters, but it also does an affordable range of smart home devices including smart bulbs. 

As well as color and white bulbs, it's one of a few brands that also offers smart filament-style bulbs too (the model we've reviewed here) that can create a vintage-style look while still maintaining modern smart home capabilities. 

Easy to install and simple to use, the TP-Link Kasa Filament Smart Bulb offers Amazon Alexa and Google integration too, although there's no HomeKit support.

Hive active smart light bulb

6. Hive Active Light

(UK only) The best smart light for a single ecosystem

Wattage: 9.5 W | Color: 16 million colors | Color temperature: 2700K-6500K | Lumen output: 806 | Lifetime: 25,000 hours | Height: 130mm | Diameter: 60mm

Easy-to-use app
Works with an ecosystem of other smart home gadgets
Also works with Philips Hue bulbs
Needs Hive hub
Lacks lamps and ceiling light choices

If you want a smart light that fits within one ecosystem, the Hive Active Light is a good fit. If you're already the proud owner of a Hive Thermostat, plug, motion sensor, or Hive View camera, you'll know that all Hive devices can all be controlled from a single easy-to-use app, providing you have the Hive Hub, streamlining the smart home control process.

As an added bonus, Philips' Hue bulbs can be integrated into the Hive ecosystem, so if you've got this far down the list but are still thinking about the Hue range, you can go back and buy them now. 

Like the other smart light ranges, Hive has a variety bulbs, with some that change color and some that just do white, however it lacks the choice of lamps and ceiling lights other ranges offer. The light from them is very pleasant, although the bulbs do 'pulse' slightly if you turn them on using a light switch, so you need to leave the switch in the 'on' position and turn the lights on and off using the app.

7. Eufy Lumos Smart Bulb

The best smart light bulb for simplicity

Affordable

Eufy (owned by Anker) is really making a name for itself as a robovac brand, producing some of the best robot vacuums that can rival the likes of iRobot as well as some of the best home security cameras that give Arlo and Ring a run for their money. But it's also trying its hand at smart bulbs too.

It may be early days for Eufy's smart bulb offering – there's currently only one bulb to choose from – but it's easy to use and ideal for those looking for a simplistic smart light bulb.  Affordable compared to other smart bulb ranges, they also support Google Assistant and Alexa to, although there's no HomeKit support yet.

How we test smart lights

To compare the best smart lights we evaluate how simple they are to install and control. We assess how quickly they respond to commands such as dimming or brightening the smart light bulbs, as well as changing the color and creating groups of smart light bulbs that can be controlled at the same time, both when we're at home and when we’re away from our property. 

We also assess each design on any voice control capabilities and it’s home automation features. For each model we wanted to know how much choice in different light fittings were offered, the extra kit such as hubs, dimmer switches and motions that’s also available for the smart lights and that it didn’t require reading a thick instruction manual before use. 

What to consider when buying a smart light

What to consider when buying a smart light

When it comes to selecting the right smart lights for you, there are a number of considerations you must make before choosing a particular model. 

Start by checking the type of fitting the smart light bulb has and whether it's compatible with your existing lighting or if you’ll need to buy adapters. Also decide whether you want lights that glow one static shade or offer different tones of white, or even a multitude of colors to ensure you create the lighting effects you want in your home. 

Now consider how bright the smart light bulbs are. The brightness of LED bulbs is measured in lumens unlike incandescent bulbs, which are measured in watts. With incandescent bulbs, higher wattage means a brighter light but as LED bulbs are more power efficient that’s no longer the case.  As a guide an 800 lumen LED bulb gives off the same amount of light as a 60w incandescent bulb, while to replace a 40w bulb with light of a similar brightness, look for an LED option that offers 450 lumens. 

Some smart light bulbs connect to the internet via Wi-Fi and can be controlled when you’re at home, and when you’re not around. However, other models use Bluetooth and require extra kit if you want to switch them on and off remotely.

It’s also worth noting that not all smart lights integrate with all voice assistants, so if you already have Alexa, Google Assistant or Siri (through Apple Homekit) in your home consider whether the smart lights you’ve selected are compatible.

Also consider whether they will work with other smart home devices you have installed, such as home security cameras, video doorbells and smart lights.

Are smart lights worth the money?

Smart light bulbs are more expensive than traditional incandescent bulbs, which may leave you wondering if they are worth the money. However, we think they very much are worth it. 

As we've already mentioned, the best smart light bulbs are LED, which have a longer lifespan than their incandescent counterparts. On top of that they also use less energy, which is not only good for the environment, but also has less of an impact on your wallet too. When you couple this with a longer lifespan, the investment in smart lights is most definitely worth it. 

How do smart light bulbs work?

Like the best smart home devices, smart lights use wireless technologies to connect to your smartphone and allow you to control the bulb from an app. 

Many smart bulbs use Bluetooth to pair directly to your phone, but these smart lights can’t be controlled when you’re in a different room, or further away, because Bluetooth is a point-to-point connection. 

If you want to control your smart lights when you’re away from home, look for bulbs that either have a hub, such as Philips Hue, or use a cloud service - for example, LIFX - that can relay commands from your smartphone to the cloud and back to the smart light, if you’re not connected to the same Wi-Fi network.
