The LEDs are all individually protected with shrink sleeves against entering wetness,
the luminosity of the LEDs (0.06 watts) can be seen very well and good at long distance.
The fairy lights has a very long supply line, only then begin the first LEDs. The fairy lights, to 19.05 m, distributed LEDs, is quite sufficient to decorate a medium sized fruit tree.
There is a magnetic body to absorb the voltage variations and external disturbances on the supply line. Similar to a VGA monitor cable.
Whether the magnet in the long run, however, can only show rust attaches the long-term test with normal weather conditions.
The fairy lights can I due to the very good brightness and low power consumption of 7.2 watt only recommend.
