with a digital ballast you save what1-3 dollars a month in a year 12-36 dollars a year you save.come on if i want to switch to save ill save better than that...lightmeters can tell you whats brighter and what brightness lasts longer,, like i said my ballast does not make no noise and its magnetic,had it only pay 30 extra in the states with a 400 watt hps.digital is good but yoou still would do the same thing you will do with a digital as you will with a magnetic.
