I have 4 Ushio 400's 20,000K run on 220v Icecaps.I also have 4 250 watt 20,000K XM's 110 volt run on Icecaps.The XM's are bluer.Ushio is a German design and made to run on higher voltage.I would be using Ushios 250 watt 20,000 K's if they made them but they do not.They make a 10,000 K which is a good bulb.The XM's are cheaper but I like my Ushios and do not plan on replacing them with XM's .I hope I have given some useful information.

Dont make them?
They are out there, but like the poster said, how are these USHIO's compared to the XM's.
