Your ATI Straton postings here have been an absolute wealth of information and have helped me not only order the lights (4 of them), but starting the process of installing them. I hope you don’t my if I ping you on occasion as I go through my learning pains. I do have an initial question....I ordered four lights and got them properly hung this past weekend. When I powered them-up, three of them came-on with no problems, however, the fourth light never came on properly. A small portion portion of the panel lights-up in a bluish color and nothing else. I have unplugged and re-plugged back in several times and have waited over 1 hour to see if the condition would change - but nothing. Do you think I have a bad light? How hard is it to speak with someone at ATI?
