So I've recently switched from T5 to MH. 2xRadiums on M80 ballasts. They look great. Growth is decent as well. Everything aside, I want faster growth. Plant speed growth. Considering trying out some 10k bulbs for a year to get the tank filled in faster. My radiums are 5-6 months old now.
My biggest gripe about them is that they're mogul hqi bulbs. So...if I want to change, I have to get either different reflectors, or different ballasts...or do I. If I wanted to try, say, xm10k, or even iwasaki 6500k bulbs, could I just use my M80 ballasts or will it torch them. What kind of difference in bulb life would I see with my M80 ballasts versus switching to some galaxy or Coralvue e-ballasts?
