While testing out my flood lights for the coming year, I noticed that if I do a run off them (turning one on at a time) the lights stop working. If I turn them all on white at once they work fine. If I do runs of any other color they work fine (oops, I guess I should say colour... ). I made a fast video with my phone. Not sure why it came out so cruddy but it gets the point across. https://dl.dropboxusercontent.com/u/12135160/DMX%20Problem.mov Any thoughts?
