If you are going to use it at 400 for the most part, I'd get a 400 bulb. In my opinion it will perform better than the 600 @ the lower wattage. Also it might not be good for a bulb to be under powered. Not sure about that at all, i just know that lost of things like being powered at a certain level and performance and lifespan drop off when the proper power isn't supplied.I also have dim able ballast I'm going to buy a mh veg bulb for my rhino tomorow, should I just buy the 400w bulb as that's all I plan on using or use a 600w bulb at the 400w setting
Plus a 400 should be a little cheaper than a 600.
