It really depends on your baseline allotment and how much of that allotment is being used already. That being said your most effective method of keeping the impact down is by looking into saving energy elsewhere in your home. This can be easy in a large home, and much harder in a small one.
With a 400W light your looking at about a 150Kwh to 250Kwh additional per month so the first thing to do is see how close to your maximum Kwh allotment you are. If you can handle the extra usage in your allotment your all good, if not then you could be looking at going into the triple bonus round and getting a really off skew bill. this can be avoided by doing as suggested and save elsewhere.
