Doug, if your getting that much brightness out of a radium don't ever sell them. a 10000K 175watt easaly over powers a radium bulb and make the tank more white than blue again..
I have seen radiums on normal ballast and on the son agro in 3 different tanks now and they are not that bright.. I have see a 400 watt Iwasaki and it is bright (ugly but way brighter than the radiums)
the deal with the radiums, which I am sure you know, is the prettyness not the brightness, even on the son agro they are not brighter... just less blue, well ok that could be construed as brighter.
my point is unless you have a burnt out iwasaki, as ugly as they are, they are way way brighter than a radium could ever be.. well unless we try hooking it up to 220 directy :twisted: hmm...
Steve
