After hours of reading, analyzing, and contemplation, I came to the conclusion that a 250w IceCap ballast with a 250w XM SE bulb would be a good addition to my tank.
I was just about to purchase these items and then I noticed that marinedepot.com explicitly said that IceCap ballasts cannot run XM bulbs.
"This ballast will power any metal halide 250-watt bulb other than the 'XM' brand bulbs."
Now, in my hours of reading, I never came accross any other source that made this exception. In fact, I seem to remember several sources talking about the exact same ballast/bulb combo.
So what's the deal? Can I drive an XM SE bulb with the IceCap ballast, or is it a bad idea.
If, in your opinion, it is a bad idea, what would be a better ballast for an XM bulb?
Thanks in advance for any advice,
AEB
