That's what scares some off. No the ballast only uses the watts of the bulb and the ballast will not degrage as fast. Normal ballast life is 5 years. so much long with smaller bulb. Now if you put a 1000 watt bulb in a 400 ballast it would try and pull a 1000 watts through a 400 and that's like crossing the streams. Very bad things will happen. We see a big drop in the electric bill when we switch from a 1000hps to a 400mh with the switchable ballast.
