Well in this set is that the fairy lights 60 LEDs (instead of 30) per meter has, and thus the light distribution is more uniform. The LED chain is provided with a relatively strong layer of plastic and should be protected against splashes thus at least. Not of course that the large controller with 44 buttons and many functions and a 230V power supply are included.
The instruction manual supplied for the controller is rather moderate. Search the internet for "LED Controller 44 key operation" and you will find much better instructions.
