Yep. A contractor working in the same bldg as me wanted to show me something. An entire hallway of LED can lights cycling off and on every 30-60 seconds. They were installed this morning in a grid ceiling with no tiles installed yet. Upon further investigation, the fixtures are 120-277v rated, but the thermals were 120v rated. They are wired 277v. He has 2 skids of these fixtures sitting on the floor and 50-60 already installed.
