Nope, nobody uses them.








J.K. They are all very popular, now what was your question again? Besides "Anybody use these?"

I have only used the 20K XMs, and have been very pleased with them. Nice blue color without being too blue. Am getting nice colors with them, and really good growth.

I have used radiums and XM's. No contest. The Radium smokes it in every way possible. Better color, Better Growth, Better PAR.

I have used both the Radium and the XM bulbs and prefer the Radium.

I have used both the 250 watt Radium and the 250 watt XM 20K and liked both but if forced to choose, I prefered the Radium.

Radium give you great results. However, you have to replace the bulbs more often. XMs also are good bulbs.

I have 2 20K radiums that I am just now replacing but have an AWESOME blue too them!
