i run the lumatek 400w dimmable ballast and a 400w radium bulb. are there any consequences to running the 400w radium on the 250w or 250 hqi settings? or should i only be running the 250w radium if i only plan to use the 250w setting? just wondering what the differences are from - is it safe for corals and will it provide proper spectrum/par to how it affects bulb life
