Did you measure the current with a DMM or a current probe and a scope? The reason I ask is because most DMMs are too slow to capture the real startup currents. The initial current draw may have been even higher than what you measured and been the cause of your trouble. When I measured the Apexcone ballasts, the initial draw was above 14A, then quickly dropped to a lower value which eventually tappered to the steady state current after many seconds.
