no I don't agree with this at all.. ther eis a lot more that will affect bulbs life than a extra 30 watts.. for one the CCF on the Son Agro is lower than on a refulare 400 watt MH ballast.. this increases bulbs life. Also you are using a started instead of relying on open current volatage to start the bulbs.. this also increases bulb life..
so as you can see I am leaning towards the side that says it will actualy last longer over a regular 400 watt ballast.. but I have no proof.. only theorys.. which is the same as the other side.. no proof only theorys.. untell we can test them in a long term enviorment.. we will not know.
if I go to Brads once a month and test his it might be good but we are at month 1 of that test.
