150W 20000K Metal Halide Bulb - XM or Ushio or Radio - Please rank

[klla310]

Hi, guys or gals

Do you know which is the best 150W Metal Halide Bulb for SPS colors and growth? Please rank with 1 being the best. Please include your experience of each as well. I used Ushio before. I like the bluish white shade, but some of my SPS are not growing and losing color. What do you think? Thanks.

XM, Ushio, Radium

Radium is the best

If ur SPS are losing color and not growing its most likely ur water not ur light.

I agree with jay. Phoenix gets my vote as well

Phoenix or Radium. Both have good color and great par. I like the Radium a little better, but it's kind of hard to find right now, although reefgeek has them in stock.

1. Radium
2. Phoenix

Both great bulbs, Radium edges out the Phoenix but just barely. Bang for the buck, especially when sales happen, Phoenix every time.
