What are smart lightbulbs?

Smart light bulbs are LED bulbs that connect to your home’s Wi-Fi or Bluetooth and can be controlled using a smartphone app, voice assistant, or even automated routines, making them a versatile choice for smart lighting. Unlike traditional bulbs, they offer much more than just on or off—they let you change brightness levels, switch colours (with RGB options), and schedule lighting scenes to match your daily routine.

Most smart bulbs work independently, meaning you don’t need to change your switches or wiring. Just screw them into a standard fitting, pair them with your app or smart speaker, and you’re ready to go.

Benefits of smart bulbs

Easy to install

One of the biggest advantages of smart bulbs is how simple they are to get started with. You don’t need to rewire anything or hire an electrician—just screw the bulb into your existing socket, download the companion app, and follow a few basic steps to pair the bulb with your phone or smart home hub. Whether you’re upgrading a bedside lamp or your entire living room with smart LED light bulbs, installation typically takes minutes, making it an ideal choice for DIY enthusiasts or renters.

Remote control

Forgot to turn off the hallway light before heading to bed? Or want to light up the house before you arrive home after work? With smart bulbs, you can control your lighting from anywhere using your phone or tablet. This level of control is convenient and it also helps you save on electricity and adds a layer of security by allowing you to simulate occupancy when you’re away on holiday.

Mood setting

Lighting plays a huge role in how a room feels. Smart bulbs with colour temperature adjustment or full RGB capability let you tailor lighting to suit any occasion. Choose a warm golden tone for a relaxing evening in the lounge, a crisp cool white for focused work in the kitchen, or even vibrant colour scenes for parties or children’s bedrooms. You can transform your space at the tap of a button—no redecorating required.

Energy efficient

Smart lightbulbs typically use LED technology, which is far more energy-efficient than traditional incandescent or halogen bulbs. That means lower electricity bills and a smaller environmental footprint. Many smart bulbs also offer real-time or historical energy usage data through their apps, helping you identify patterns and reduce unnecessary consumption.

Voice integration

Smart bulbs work seamlessly with voice-controlled assistants like Amazon Alexa, Google Assistant and Apple Siri. This hands-free functionality becomes especially useful when your hands are full, you’re cooking, carrying the baby, or simply want the lights off without moving from the sofa. Voice commands like “turn off all downstairs lights” or “set the bedroom light to 20%” quickly become part of your routine.

Scheduling and automation

With smart bulbs, you can create daily routines that match your lifestyle. Wake up gradually with a slow fade-in of soft morning light, have your lights automatically turn on at sunset, or set everything to switch off when you leave the house. Automating your lighting not only saves time but also supports better sleep habits, boosts productivity, and helps maintain a consistent rhythm in your home—even when you’re not there.

Aspects to consider before buying

Connectivity

Smart bulbs connect to your devices in different ways—typically through Wi-Fi, Bluetooth, or Zigbee.

  1. Wi-Fi bulbs are the most common and easiest to set up. They connect directly to your home internet, meaning you don’t need a separate hub. However, if you install lots of smart devices, they can start to strain your network or cause occasional delays.
  2. Bluetooth bulbs are ideal for single-room or small-scale setups, as they don’t require internet access but must be controlled within a limited range (typically from the same room).
  3. Zigbee or Z-Wave bulbs use a separate wireless protocol and usually require a hub. They offer faster response times, better reliability, and scale more easily across larger homes without clogging up your Wi-Fi.

Your choice depends on the size of your home, how many bulbs you want to install, and whether you already have a hub or plan to expand your smart home system later.

App features

A smart bulb is only as good as the app that controls it. Look for companion apps that are:

  1. Easy to navigate, especially if you’re not tech-savvy
  2. Flexible, allowing you to group bulbs by room (e.g. “Bedroom” or “Kitchen”)
  3. Rich in features, such as brightness control, colour settings, timers, and scene creation
  4. Compatible with your existing smart home ecosystem, like Alexa, Google Home or Apple HomeKit

Some apps also allow multiple user access, energy usage tracking, or integration with other smart devices (e.g. door sensors or thermostats). Exploring demo videos can give you a feel for the interface before buying.

Brightness and colour options

Not all smart bulbs offer the same lighting experience.

  1. White-only bulbs come in different tones, typically adjustable between warm white (cosy and soft) and cool white (crisp and energising). These are great for general use in kitchens, bathrooms, or workspaces.
  2. Colour-changing bulbs (RGB or RGBW) can display millions of colours and are ideal for bedrooms, lounges, playrooms or entertainment spaces. They’re perfect for setting mood lighting or creating fun scenes for holidays and parties.

Also consider the brightness, which is measured in lumens. A standard 60W replacement bulb gives around 800 lumens. If you’re lighting large rooms or replacing multiple high-output bulbs, ensure your smart bulb can match that brightness.

Bulb type and size

Smart lightbulbs come in various shapes and fittings to match standard fixtures found in UK homes:

  1. E27 – large screw cap
  2. B22 – bayonet cap (common in older UK homes)
  3. GU10 – typically used for spotlights or ceiling downlights
  4. E14 – smaller screw cap, often used in lamps or chandeliers

Before purchasing, check the base type of your existing fittings. Also pay attention to the bulb’s dimensions—some smart bulbs are slightly larger due to built-in tech and may not fit snugly into tight fixtures like enclosed lamps or recessed ceiling spots.
