Radium 20K

[Jayson]

I have not tried them on Blueline(not a big fan of them) I am still waiting for he 12 Ice Cap I ordered to come in. The bulb expectancy is 11-12 monthes if run on the proper ballast. I you run them on a Pfo hqi you will get aprox 6-8 months. Radium does not even recommend the ballasts. Eye may last longer but there is just no comparison to color. Hope this helps
