Tom,
Thanks for the heads up! Do you think the Phoenix 14k's are as blue as my Radium? I need to check your thread pics out again. I run the Radium 20K and one ULV 75/25 T5 bulb. This brings out the pinks in the coralline algae.
Thinking about changing over all together with a Hamilton T5 unit just to try it out! I know I could really fine tune colors then and save a bit on electricity for sure!
I just like the metal halides. Bummer, as IceCap no longer builds the ballast I run! I know there are others. Hope my ballast lasts a few more years if I decide to stay with it!
Just so you guys know, the ballasts make a big difference many times in the colors of the bulbs as well....
