Please help identify this bulb base. Also, is this a good buy?

I can get these for $7 a piece, but I don’t know what they “screw into”… obviously not an E27 base.

Anyone know what these are good for? Good deal?

Thanks

Looks like a GU24 base.

Yeah, it says GU24 on the box. See top line of top box, at the end.

The package says the base is a GU24 base. It is one of the 'newer' bajonet-bases, but the GU10 (similar but smaller) is more common.
