Ushio vs. XM


I was wondering how 250watt 10k, XM bulbs compare to Ushio 10k bulbs. I have Ushio and really like the crisp white color. How does XM compare? Is it similar, bluer, or more yellow.

From my experience with running 175W XM bulbs and 175W Ushio bulbs, the XMs appeared crisp white, while the Ushios were white with a hint of yellow. My experience seems to be consistent with what I've read on various message boards.


I just switched from the ushio10k to the xm 10k and like the xm alot, seems to me to be a crisper white after the burn in, I had used the ushio for years and just made the switch because I had heard alot about the xm plus the price is a big plus.


Just got my new XM 250 watt bulbs and I like them very much. I just wish I had a PAR meter to see what they are really putting out.
I agree with what RobChuck says about the difference between the two bulbs are. There is a bit more yellow to the Ushio's and the XM's are putting out a very nice crisper white.
