Started building some new haloween elements tonight and noticed the string on lights (12v, ws2811) were glowing feintly soon as i plugged in the controller? Checked the wiring - Everything looked good. Tried a different string- same issue. Tried a different controller - still same issue!! Setup: Alphapix-4 controller (also tried it with pixlite16) 350w power supplies from holidaycoro (chinese). I tried swapping things around and kept getting varrying degrees of the same issue. I COULDNT eleminate was the holidaycoro powr supplies... I have 5 of them- all the same model. Any ideas? This is driving me nuts!!!!
