There is too much confusion around these lights to get a good understanding.
I am seeing people refer to a v1 and v2 of the string being out there... I was aware of only a v1 that was released. there were different factory runs, and that might have made a difference in quality... but all of this is unknown.
a v2 with 5050 LEDs was discussed for this year.
the v1 strings are being reworked now with Timon and others involved in the redesign and testing. the first runs are being tested now, but there are still questions about the plastic being used.
the v1 strings had different results based on user, but overall it was suspect enough that I wouldn't trust them. if you have a batch of them -- maybe you'll be successful with them, but most likely you will not.
the best thing IMO is for the new versions to be "rebranded", and let the "Technicolor" name die. Otherwise we will continue to be confused over this mess.
