I wonder what socket standards are available for 12V LED DC bulbs. I'm struggling to find GU10 and E14 12V DC COB bulbs anywhere but on this website:

This is a small Norwegian company, no way they are manufacturing them. They have pretty good reputation as well so I doubt they are fake.

I've been digging in eBay and AliExpress for days - NOTHING, ZERO, NADA. How is that possible? Logically I started asking myself the question are GU10 and E14 sockets approved standard-wise for 12V connections.

If you help me out with alternative sources of 12V DC COB GU10/E14 bulbs (cause the Norwegians do not ship abroad) I'd be very helpful. Of course, if such a unicorn exists
