Colour changing smart bulbs are one of the most impactful — and accessible — smart home upgrades you can make. Swap a standard E27 bulb for one of these and you gain millions of colour options, voice control, and scheduling, all without rewiring a thing. The UK market has never had more choice, so we've cut through the noise to find the best options across every budget.
If you're new to smart lighting, you might want to read our guide to the best smart bulbs in the UK for a broader overview — this article focuses specifically on full RGBW colour-changing models.
Our Top Picks at a Glance
Here are the five best colour changing smart bulbs available in the UK right now, from budget WiFi models to premium Zigbee systems.
1. Philips Hue White & Colour Ambiance E27 — Best Overall
From around £24.99 per bulb, the Philips Hue White & Colour Ambiance is the gold standard for colour smart lighting in the UK. It delivers up to 1,100 lumens — bright enough for most living rooms — and gives you access to over 16 million colours alongside a full warm-to-cool white range (2,000–6,500 K).
The Hue ecosystem runs over Zigbee, which means you'll need a Philips Hue Bridge (sold separately, or included in a starter kit) to unlock the full feature set including automations, remote access, and third-party integrations. That said, the reliability and responsiveness of a dedicated Zigbee mesh is hard to argue with. Voice control via Amazon Alexa, Google Assistant, and Apple HomeKit comes standard.
The Hue app is the most polished in the category, with scene libraries, entertainment sync for gaming and film, and a well-developed Home Assistant integration via the official Hue integration. Read our full Philips Hue Starter Kit review for setup tips and long-term impressions. For those wanting Zigbee flexibility without the Hue Bridge, see our best Zigbee bulbs UK guide.
Pros: market-leading app and ecosystem; rock-solid Zigbee reliability; 16M+ colours at 1,100 lm; HomeKit support.
Cons: requires Hue Bridge; premium price per bulb; Bridge adds up-front cost.
2. LIFX A60 — Best WiFi Colour Bulb
Around £14.99, the LIFX A60 is the best colour smart bulb that works without any hub. It connects directly to your 2.4 GHz WiFi and delivers a strong 1,100 lumens in RGBW — with a dedicated warm white channel for proper daylight-to-candlelight tuning, not just a pale orange.
LIFX uses a proprietary WiFi stack optimised for low latency, and in practice the bulbs respond quickly to app commands and voice requests. The LIFX app has strong scene and schedule tools, and Alexa, Google Assistant, and Apple HomeKit are all supported natively — no bridge, no hub, no subscription.
The downside is that each bulb sits on your WiFi network, which can stress lower-end routers if you're buying in bulk. But for one to four bulbs, this is a non-issue. For a head-to-head comparison of the two top brands, see our Philips Hue vs LIFX breakdown.
Pros: no hub required; 1,100 lm true RGBW; HomeKit native; easy setup.
Cons: adds to WiFi device count; no local processing if router goes offline.
3. WiZ Colour — Best Budget Colour Bulb with SpaceSense
Around £9.99, the WiZ Colour bulb punches well above its price point. It connects over 2.4 GHz WiFi, supports Alexa and Google Assistant, and delivers a solid colour range with warm white tuning. The standout feature is SpaceSense — a passive infrared detection mode built into the bulb itself that can trigger automations when it senses motion, without any separate sensor.
WiZ is a Signify brand (the same company that makes Philips Hue), so the quality control is solid. The WiZ app is straightforward and supports scenes, schedules, and sunrise/sunset automation. While it lacks HomeKit support, for Alexa or Google households this is arguably the best-value colour bulb on the market. See our WiZ Smart Lights UK review for a detailed look at the full range.
Pros: excellent price; SpaceSense motion detection built in; reliable WiFi; Signify quality.
Cons: no Apple HomeKit; no Zigbee option; app less polished than Hue.
4. TP-Link Kasa KL130 — Best for Kasa Ecosystem Users
Around £12.99, the TP-Link Kasa KL130 is a capable colour smart bulb that fits naturally into the Kasa ecosystem. It connects over 2.4 GHz WiFi with no hub required, supports Alexa, Google Assistant, and Samsung SmartThings, and offers a wide colour gamut plus adjustable white temperature.
The Kasa app is well-regarded for reliability and the bulbs have a strong reputation for consistent WiFi connectivity, even on busy networks. If you already use Kasa smart plugs or switches, adding KL130 bulbs brings everything under one app. Our Kasa smart bulbs UK review covers the full KL series in detail.
Pros: no hub needed; good Kasa app; SmartThings support; reliable WiFi.
Cons: no HomeKit; colour accuracy a step below LIFX or Hue.
5. Govee Smart Bulb — Best Ultra-Budget Colour Bulb
Around £7.99, the Govee Smart Bulb is the most affordable colour changing smart bulb we'd recommend. It connects over 2.4 GHz WiFi, supports both Alexa and Google Home, and delivers RGBWW output — the extra warm white channel (WW) means skin tones and wood furnishings look more natural than basic RGB models.
At this price you're not getting HomeKit, Zigbee, or the polished experience of Hue — but you are getting a genuinely functional colour bulb that's easy to set up and good enough for accent lighting, kids' rooms, and experimentation. Read our Govee smart lights UK review for more on the brand's wider range.
Pros: outstanding value; RGBWW colour; Alexa and Google support; easy setup.
Cons: no HomeKit; build quality reflects the price; app less refined.
How to Choose the Right Colour Smart Bulb
Hub or no hub? Zigbee bulbs like Philips Hue require a bridge but offer a faster, more reliable mesh network — ideal if you're building a larger smart home. WiFi bulbs (LIFX, WiZ, Kasa, Govee) are simpler to start with but add to your network device count.
Brightness matters. For a living room or bedroom, aim for at least 800 lumens. The Hue and LIFX models both hit 1,100 lm, which is roughly equivalent to a traditional 75 W incandescent bulb.
RGBW vs RGBWW. RGBW adds a dedicated cool or warm white LED alongside the colour channels; RGBWW adds both. This matters for everyday white light quality — basic RGB bulbs often look slightly purple or green in white mode, whereas RGBW and RGBWW models produce a clean, natural white.
Voice assistant compatibility. All five picks work with Alexa and Google Assistant. Only Philips Hue and LIFX offer native Apple HomeKit support without workarounds.
Home Assistant users will find official integrations for Philips Hue, LIFX, WiZ, and Kasa Kira. Govee has a community integration via HACS. If local control is essential to you, Zigbee via the Hue Bridge or a ZHA/Zigbee2MQTT setup gives the most flexibility.
Verdict
For most UK buyers, the WiZ Colour at around £9.99 is the sweet spot — it's reliable, well-featured, and the SpaceSense motion detection adds real-world value. Step up to LIFX if you need HomeKit or want the best WiFi colour accuracy, and choose Philips Hue if you're building a serious smart home ecosystem and want the very best experience money can buy.
