SELETTIBird Lamp Waiting table lamp white crow

I love how this lamp looks, but it doesn't take all E14 bulbs. In the picture of the bulbs, the central bulb is the one that came with the lamp. It has a more cone-shaped connection compared with the other two. After looking inside the bulb mount, there appears to be a raised ring above the plate that connects to the bulb which prevents the flatter bulb shapes from connecting. The problem is that most E14 bulbs you can buy have the flatter shape. Perhaps in mainland Europe the bulbs are different, but here in the UK, finding replacement bulbs will be difficult. I have ended up replacing the cable and bulb mount as I wanted to use it with a Philips Hue bulb (unfortunately it's larger than the Seletti one and the bulb rests on the table).
