So I've been having issues with my 400W 20K DE MH bulbs. I have not been able to run them for more than 5 days with out having one go out on me.

My first issue was with one bulb being shorter than the other. Here is the thread on that: http://reefcentral.com/forums/showthread.php?s=&threadid=1380778

Has anyone been able to successfully run a 400W DE MH with IceCap Ballasts and IceCap pendents? Not that the pendents matter, but I want to check.
