Scared of XM

Hi Marcus,
I'm not sure why they would have those type of problems. It could be a quality control issue and also a combination of ballasts, where if the ballast is not tuned for the bulb, or the bulb is not industry standard, you might get different results.
That's just an opinion, it does seem that the higher quality lamps like German made ushios etc do not have as many color shift problems and this might go back to the quality control standard, where every bulb is made to exact specifications.

Hi,
We have a 30 day policy, so if you feel it's too yellow we'll take it back for exchange on another brand.
Keep in mind that 10K usually is normally a yellow to white color. Even Ushio is on the yellow side. Most 10K's are a little under actual 10K rating. So depends on what your prefer, personal taste etc.
If you want warm color and use actinics, 10K ushio, xm etc is a nice choice. If you want super clean crisp white, look at 10K ReefLux and if you want something with a blue tint, i would get up into the 14K or higher bulbs.

Jason, the 400w xm 10k bulb tested by someone here on RC shows a correlated color temperature of 11-13k depending on ballast. The issue raised on this thread is represented well in the pictures shown in the following thread.

Good to hear you have a 30 day policy. I assume that it applies if I get one of these color shifted xm bulbs. I love the color and par from the good xm10k's. Just nervous about getting a color shifted one.

I am sure that I will be going with the XM10K's... because I do want the color and growth.
And will be running them on probably a Blueline Eballast....
250w's...
Here is a Quote of a Quote taken from that Thread just posted...
Now, if XM said that... yeah, YA DERN SKIPPY Im sending the bulb back for a new one! haha

its all in the eye of the beholder. i have phoenix 14K's and they are blue, but i wouldnt call them superblue. in fact, depending how you look at it, it can seem white, blue, or very blue. if i have algae on the glass, it will look kinda yellow, but if the glass is clean, it looks pretty nice. i also have XM10k's (SE) sometimes they look white, sometimes kinda yellow. if i squint hard, they'll get a hint of blue 
like i said, its all in the eye of the beholder

Shawn,
If that statement was put out by XM them they are contradicting themselves.
I can personally see new growth attributed to the introduction of the XM's on my sps, especially on my digitatas. I changed to the XM's about two weeks ago.
Premium Aquatics are replacing my yellow bulb. It's been over 100 hours and the bulb is still very yellow, the other three are fine.
Cheers,
John

Hi Shawn,
I have tried several bulbs and there are many good ones out there.
But I just find XM to be the best for me I tried there 15k and 20k,but swapped back in my 10Ks right away they just rock!And you will be happy with them.
Here is a pic of 3 months growth one taken at the 21st of Ocober 2005 and the other taken the 5th of February 2006 I am using 2 48"VHO actinics.

That is nice, very !
I think that these bulbs are my best bet, dispite the occational bad bulb, the quality of the good ones seems great!
