Brad,
How do you like the 10k/Radium combo. Much brighter I assume? I'd like to go to 400's.
Jack, I don't like it much. I'm going to try 2 radium with a 10k in the center and decide which combo I can live with. Three Radiums might be enough, so we'll see.
One thing for sure is the extra bulb is giving me heat problems again.
