Does anyone know a shop that sells these connectors on their own, if they work as I'm hoping, i.e. wires in one end, RGB strip in the other end? Obviously not yet sure if they work like that... I have dropped the shop an email, maybe I will be lucky enough to get a response.
I've never found connectors that were suitable, so I have always ended up soldering, often directly onto the RGB LED strip itself, as I'm not a real fan of those connectors with the black plastic tabs you press in to make a firm connection.
