I just purchased three of these Linkind kits on Amazon UK - Two E27 9W bulbs and a (fairly useless) mini hub for just under £9 each. Throw the hub away and you’ve got two good quality zigbee lights for £4.50 each. Cheaper than Ikea!
The bulbs paired straight away with Zigbee2MQTT (switch them off and on 6 times, then leave them on) and brightness / colour temperature work.
The hub looks like this inside if anyone thinks it might be repurposed as a zigbee repeater?
