Smart bulbs have come a long way in a short time. What used to require expensive hubs and complex setup is now as simple as screwing in a bulb and downloading an app. The best smart bulbs in 2026 offer full colour control, scheduling, voice assistant compatibility and music sync — all for less than a cup of coffee per bulb.
The UK market is dominated by a few key brands: Tapo (by TP-Link) has quietly become the go-to choice for value smart lighting, while Govee and Lepro offer strong competition at similar price points.
⭐ Best Overall — Tapo L530B 2-Pack
Nearly 50,000 Amazon reviews at 4.5 stars — the Tapo L530B 2-Pack is one of the most reviewed smart home products in the UK. That level of customer validation is rare. You get two full-colour smart bulbs in the bayonet (B22) fitting for £20 — that's £10 per bulb for a product with multicolour support, 16 million colours, scheduling, dimming, and compatibility with Alexa, Google Home and Apple HomeKit. The Tapo app is clean and responsive. This is the benchmark for budget smart lighting.
- 50,000 reviews — extraordinary customer validation
- Two bulbs for £20 — great value per bulb
- Full 16 million colour support
- Works with Alexa, Google Home and Apple HomeKit
- Requires 2.4GHz WiFi — won't work on 5GHz only
- App required for initial setup
- No hub required but does need a Tapo account
💰 Best Single Bulb — Tapo L530E E27
The E27 screw-fit version of the Tapo L530 for just £8 — an outstanding entry price for a full-colour smart bulb. If you only need one bulb to try smart lighting, or you have E27 screw fittings rather than B22 bayonet, this is the obvious choice. The same Tapo app and voice assistant support as the 2-pack, at a per-bulb price that's hard to dispute.
- Just £8 for a full-colour smart bulb
- E27 screw fitting — most common lamp fitting
- Same Tapo app and features as pricier models

Perfect for bedroom or living room lamps where you want the convenience of app or voice control without the novelty of colour. The same extraordinary review count as the L530B — Tapo clearly knows how to make smart bulbs that just work.

🛒 Smart Bulb Buying Guide
B22 bayonet vs E27 screw — which do you have?
UK homes traditionally use the B22 bayonet fitting — the push-and-twist style. E27 is the screw-in European style, now common in modern lamps and light fittings. Check your existing bulb before buying — the fitting type is printed on the base of most bulbs. Both are widely available in smart bulb form.
Do you need colour-changing?
Colour-changing bulbs are fun but for most rooms you'll use warm white 95% of the time. If you're kitting out a living room or bedroom lamp and want scheduling and dimming, the white-only Tapo L510B is £6 cheaper per 2-pack than the colour version and the light quality is often better for everyday use. Get colour for accent lights, entertainment rooms or kids' bedrooms.
Do you need a hub?
The Tapo, Govee and Lepro bulbs in this roundup are all hub-free — they connect directly to your WiFi. You don't need to buy any additional hardware. Just install the bulb, download the app and you're up and running in minutes.
🏆 Our Final Verdict
The Tapo L530B 2-Pack at £20 is an almost impossible recommendation to argue against. Two full-colour smart bulbs for £20, backed by nearly 50,000 customer reviews. Start here. If you want the best features and Matter compatibility, the Govee RGBWW at £19 is a single bulb but genuinely more capable.
