All I can say is that I ran the system like this over 10 occasions last 
season, and the runs were anywhere from 30 seconds to over 5 minutes at a 
time, and the transformer was still ice cold. The ballast early in the 
season was set to 25 amps, and later in the season, I ran a new circuit and 
increased the current to 35.
