- Mood setting: Millions of colours and brightness levels let you create the perfect atmosphere.

How Much Can You Save with Smart Bulbs?
Smart bulbs use 80% less energy than old incandescent bulbs. Let’s do the maths for a typical UK home:
- Average home lighting cost: £45–£65/year per bulb (incandescent)
- Smart LED bulb cost: £5–£10/year per bulb
- Annual saving: £35–£55 per bulb
- With dimming & scheduling: Additional 10–15% savings
For a 10-bulb home, you could save £350–£550 annually. That pays for the initial investment in 12–18 months. Read more in our guide on smart home energy savings.
Compatibility & Setup
All bulbs listed here are compatible with standard UK light fittings (B22/E27 bayonet and screw). Setup takes minutes: screw in, download the app, scan the HomeKit/WiFi code.

Frequently Asked Questions
Do Smart Bulbs Work Without Internet?
Most smart bulbs can be controlled locally via app if on the same WiFi network. However, remote control (accessing from outside your home) requires an internet connection. Some systems like Philips Hue (with Bridge) offer better local fallback options.
Which Smart Bulbs Are Most Energy Efficient?
All modern smart bulbs (A+ rating) use roughly the same energy. The difference is in scheduling: bulbs you automate to turn off actually save money, while bulbs left on continuously cost more than standard LEDs. Behaviour matters more than the bulb itself.
Can I Use Smart Bulbs in Dimmers?
Most smart bulbs don’t work with traditional physical dimmers. Instead, you control brightness via app or voice commands. If you have a dimmer switch, you’ll need either: (a) a smart dimmer switch instead, or (b) a bulb designed for dimmer compatibility. Check the product specs before buying.
Do I Need a Bridge or Hub?
Only Philips Hue requires a hub for full colour control (though basic on/off works without it). LIFX, Wyze, and Meross connect directly to WiFi. If you already have an Alexa Echo or Google Home, some bulbs can use that as a hub.
Are Smart Bulbs Compatible with Each Other?
Not directly. Philips Hue bulbs don’t natively talk to LIFX bulbs, for example. However, you can control different brands in the same Alexa or Google Home routine, so they work together in automation. For a unified experience, stick with one brand.
Our Recommendation
For most UK homes: Start with Wyze bulbs (£8–£15) if you’re on a budget, or Philips Hue (£15–£25 + bridge) if you want the best app and reliability. Both work flawlessly with Alexa and Google Home, and the energy savings pay for themselves within 18 months.
If you’re a HomeKit user, pick Meross (£12–£20). If you want zero hub hassle, LIFX is your best bet.
