Availability of Radium bulbs

[lastlight]

So Marie you're not running those bulbs any longer? Can I ask why and what you run now?

I'm even considering going the opposite direction and going with XM 10ks lol.

PAR monsters (also wattage monsters though). I know everything is relative but I have heard some people refer to the XM 10k as a crispt white light? Is this just a nice way of saying super bright yellow?

I imagine the growth (and coral burn) potential would be unreal.

On Sanjay's site the Radiums output 85 ppfd each on M80s and the Xm 10ks are 182! Thinking I could raise my hood a bit to improve the terrible access I have easily with such output.
