Full Review

LIFX takes a different approach to smart lighting: no bridge, no hub, no extra hardware. Each A19 bulb connects directly to your 2.4GHz Wi-Fi network and is controlled via the LIFX app or any major voice assistant. That simplicity is one of its biggest selling points over Philips Hue, which requires a hub costing an additional £50+ before you can use it. The colour range is genuinely impressive — 550 billion colour steps using RGBW LEDs that blend colour and a dedicated white channel, giving you access to everything from vibrant party colours to warm whites at 1500K all the way to daylight at 9000K. The white range alone is more comprehensive than most competing bulbs, and because a white LED chip is included rather than mixing colours to simulate white, the actual white light quality is much higher. At 800 lumens, these are bright — brighter than a standard 60W incandescent equivalent — and dimmable through the app or voice without any specialist smart dimmer switch. The LED driver is rated for up to 25,000 hours, or roughly 22 years at average UK usage, so the higher upfront cost versus a basic smart bulb is partially offset by longevity. The two-pack at £42.99 works out to just over £21 per bulb. That's at the premium end of the smart bulb market but buys you genuinely hub-free operation, which saves significant setup hassle in homes where a Hue ecosystem isn't already installed.
