Radium Mh Bulbs

What's unique about Radium MH Bulbs in comparison to other MH bulbs, especially the 20K's?

I think the biggest thing is that they'll potentially put out the most intensity of any 20K bulb when run on an HQI (M80) ballast. This also makes them look less "20K" too, though. Other than that, not much unique about them IMO. Some folks think they're a little more purple than other 20Ks when run on a non-HQI ballast and I'd agree.
