Maybe a little off-topic, but, the Iwasaki webpage says not to run their bulbs on "combination MH/MV ballasts." To my knowledge just about every ballast we can buy is a combination MH/MV! I.e., M57/H37, M58/H38, etc. etc. Even the EYE Electric (Iwasaki) ballasts appear to be both mercury vapour and metal halide!
The reason I am confused about this is, for a time, I ran a non-R and a R 250W side by side. I never really could perceive much of a difference. Unless I am colour blind (who knows maybe I am), I wonder if this means that I'm running the "R" version on a suboptimal ballast because my ballasts are for sure "250W MH or MV."
So what's up with that, any ideas? I've tried looking for a H38 ballast (err. or whatever a 250W MV is) that wasn't also a M58 (250W MH), and, well, not that I looked all that hard, but all I could find were these combo ballasts. Does "combination ballast" perhaps refer to something else?
