This might be of interest to some of you. I wanted some 24v single colour green, red and amber light strings for an upcoming project, after a lot of emails to Chinese manufacturers I ended up getting the strings for 42 cents/M. It wasn't easy communicating with the suppliers, I had to provide a sketch of what I wanted, even then one of them wrote the wrong voltage on their quote. The product I received is good, the wire is black, good size conductors and the heatshink is all glue lined, no complaints. Attached is a spreadsheet with the prices I received.
