Gotcha and totally understand, that's why in my post I also said to grab a power monitor so that you can check/confirm what the draw of your particular set up is. As mentioned, mine draws less and I also mentioned that a different set up could draw more. The power monitors are less than 30 bucks depending on which one you buy and can be a very handy device to have around the house.
A 250 MH that draws 400? That seems a bit steep and sounds like an inefficient set up. Pre mature burnout etc..
