Very nice lights! They’re elegant, well made and reasonably priced for what you get. I was confused by the bulb as there are no threads to screw it into — instead there’s some metal that looks like a spring. But the recommended E12 (standard chandelier bulb) actually screws in easily and works just fine. Never seen a bulb socket like this before and spent a lot of time googling it. I should have just tried installing the bulb in the first place! All good. Recommend these lights.
