I personally like XM bulbs whenever possible but you need an electronic start ballast, not sure what type of balast your light comes with.
That is not true......You can fire an run XM bulbs on a ballast like the old PFO's and they were not electronic by any means.....
Ushio's would be yellow compared to a Phoenix, but as we all know depending on the ballast driving a bulb will dictate color a bit as well......Another thing and this is dealing with SE MH bulbs, the nipple orientation of the bulb will also affect color as well.
XM 10k's are good for growth as well, but trust me not very appealing to the eye, where as when you get to the 14k-15k XM appeasing to the eye, but not great numbers if you check them out.
There is an old thread or site out there and Sanjay had the info on his site as well, that listed the efficiency of bulb ballast combination, and also had pics as well to give you an idea.
