I put several strands of LED lights in a 100' tall tree. Each strand consists of 3 - 30 bulb strings connected end to end. All was well, until yesterday one of the strands (total of 90 bulbs) didn't turn on. I swapped out the control box to no avail.
Would a loosened bulb in the first string cut power to all the others, including the connected strings?
