HPS electricity consumption

Hi there,

I thought that 150W hps used 150W of electricity but it seems that the ballast also consumes electricity and therefore I read that some 150W hps systems consumes 200W and other up to 300W.

Could anybody confirm this information ? coz if it's true it may not be worth it to get the low wattage hps after all.
