Good 175w Bulb?

[Renmar]

I am needing to get a new bulb for my 40gal breeder. The bulb that is currently in there is a 175w 15k Iwaski bulb. However, I am looking at getting an XM 15k bulb or a 20k bulb. I, however, haven't seen either in action.

If you guys have these bulbs - mind showing me some photos so I can make a decision on which I like more?

Thanks!

Ren,

The 15K XM has terrible PAR, the bulb you currently have is very nice so why not stay with it???

The money is a factor atm, as I can't afford $100 on a bulb.
