2-wire

Evening All! This is my first year of 'stepping up' the christmas lights. Last year was a number of 2-wire Bunnings lights, however having them all flash out of sequence caused me some significant distress! This year I am fixing it with a DMX2-24 to at least bring different runs all flashing...

Last year I bought a bunch of boxes of Vue LED strings from Myer in their post Christmas discount period, but this year it's looking like there might not be much left over.. Does anyone know where Myer, Big W, Bunnings etc all source their lights from? I'm specifically looking for the 2-wire...
