so would i have to match the voltage for the bulb with the voltage of the fixture or the voltage of the ballast because i know the fixture is 600 v but not to sure what the ballast is. and if the ballast is 400 watts then shouldn't it make less noise then 1000 watt ballast would when turned on, im just woundering about the noise thing because i had a 1000 watt light last year and grew with that and it made less noise then the 400 watt light i have now does
