Sorry, 8 total fixtures...two rows of 4 fixtures each with the two hot legs and one shared neutral back to panel. The transformers are kits multi tap with a cap. Like 120/208/240/277 with a capacitor in series with the lamp, no igniter. The same as what was in the fixtures 400watt M59. I started to change them out today, haven’t found anything conclusive as yet, although, I swear I keep finding loose wire nuts without evidence of direct short to the box. Like,.. I go to take a box cover off and a wire nut falls out. What the fu#!.
