HPS igniitors are like 15$. Not sure howmuch conversion bulbs are, but i recall hearing they are less efficient. Wouldn't it be possible to throw an ignitor in there or does an MH ballast not have the extra (blue?) wire for it?
Efficiency depends on the bulb. I spend the extra 20 - $40 for Hortilux and when I compare the light intensity with my cheaper bulbs the Horts blow them out of the grow room. I'm not replacing them every 2nd grow either. So what if they're 10% less than new they're still way better than cheap bulbs like the PlantMax and other chinese junk.
If you know what you're doing I'm sure you could add in an ignitor but I'm not messing with that myself.
