I've got a strand of low wattage LED XMAS lights plugged into an NSI pack that has intermittant flicker issues. I'm trying to see if anyone else has had this problem or knows what I need to be looking at. The LED XMAS lights are a simple hardware store strand with a fuse. I've got a ghost load on the pack with the string itself, the ghost load flickers as well, which seems to indicate a data issue. The NSI pack is terminated. I plan on switching the practicals to a non-NSI dimmer tomorrow, but I was wondering if anyone had any thoughts on the potential causes of this problem.
