XM 20k or Radiums?

[ReeferKeith]

I am coming up on the one year mark with my current bulbs, 2 SE EVC 14K 250 watts. I have been very pleased with the growth and color of these bulbs, and I would highly recommend them. But I would like to try something different, a little bluer. I keep mainly SPS but I do have a few LPS and zoos.

So I would like to get your opinions, and or experiences with the following bulbs. XM 20K, and Radium 20K. If you have a different bulb you are using and are getting great color or are just overall pleased with let me know. Thanks!

No opinions??

I voted Radium because I don't really care for the grey blue color of the XM's.

I believe you'll need an HQI ballast for the Radiums.
