To short !!!...the last two sets of RGB LED strip kits that arrived are only 1M; they should have been 2M length. Contacted the supplier to complain and they say that's what I ordered - doubt that. To busy now so I'll think about that and follow-up later.
That's only 1M on that spool and the code has the _2 on the end.
Furthermore the 2M length fills the whole spool!
