Actinics? Which brand is the best with 20K MH

[dotcommer]

On my 300 Gallon build, I just purchased 20K Radium 400 Watt bulbs.
I am wanting to add Actinics and was wondering what most people are using and like the best with a 20K MH light.

I have been reading that the Giesemann Actinic Pure Bulb is recommended.

What are your thoughts on using Actinic with the 20K MH lights.

UVL SuperActinics are really nice. I run them (VHO, not t5s) with my 250w Radium and have had good results. I was told that the VHO UVLs might not be available much longer, but that likely won't be of concern to you if you're going with T5s.
