Hey guy im having some problems..I installed 44 ha lts in a local chevy dealership. They are about 16 by 16 in square, about 9 in deep. They all have a capasitor and a ballast. Well the problem is almost everyone have had caps changed about 30 percent have had new ballasts. They all have multi tap ballasts , were are using 120 volts the farthest away from the panel is about 60 feet. We have even took ko"s out thinking it might let some heat out , we have also checked for voltage drop... Can someone help we do alot for this dealer they have 5 car lots they baught the fixtures but its costing them a fortune in service work to replace bulbs, ballasts,capasitors....
