As expected, the the half completed mega tree brought the light sticking issue with it from 2008. The cause in simple terms is that the LED light strings on the tree draw so little power that the light controllers have difficulty ‘seeing’ the light sets, so fail to switch them off.
The solution is to raise the power use for each affected channel.. making up a DIY light fitting that plugs in to a regular powerpoint would cost $6 or more for the parts plus time which is at an absolute premium, so the next best thing is a whole bunch of budget mini rope light shapes for around $7 each.
Fantastic job you should check out this guy in Melbourne he must have the biggest mega tree I have ever seen, his website is http://www.melbournechristmas.webs.com keep up the good work I’ll be checking it out this year again.
