Phoenix 175w SE 14k?

[Angels 2010]

I'm going to be replacing my bulbs here shortly and have come across the fact that phoenix makes a 175w SE(i thought they only made 150w DE) I have heard these bulbs are nice but have not been able to find any par rtings on them. Can somebody hook me up with a link? Or any info on these bulbs at all? Personal experience is also a huge plus.
They will be run on an old magnetic ballast, not sure the brand.
Thanks, Dave
