So, in the UK, this:
is a lightbulb’s connector for a standard, basic, normal lightbulb.
In the US, this:
is your bog-standard lightbulb connector.
Now I knew this beforehand, and I knew that I’d probably have to look a bit harder to find the bulbs I want. However, what is frustrating is that the LED B22D bulbs I can find on Alibaba and Goodluckbuy, and so on, list themselves as being 85V or higher. But I’m a bit wary of ordering multiple bulbs without knowing if they’re any good.
But when I look on Amazon or ebay, they’re all listed as 240volt.
I’m sure I’ll find what I want eventually… Not that I can afford to buy them until I’ve been paid anyhow.
