LIFX GU10 (International) Wi-Fi Smart LED Light Bulb, Adjustable, Multicolour, Dimmable, No Hub Required, Works with Alexa, Apple HomeKit and The Google Assistant, Pack of 2
Cheapest I have ever seen the LIFX GU10s (and in stock). Expensive for a smart bulb but usually these are £50 each or (£45 each in pack of 2).
Cheaper smart bulbs may be available but for LIFX that need no hub, this is the best price i have seen (that is in stock and shipping)
