I bought them from Premium Aquatics in the states, shipped by usps so no brokerage fees and for some reason no taxes either

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.

Funny guy! Yeah it seems all Radiums are currently not being imported. There are still a few US vendors with the 250s I've found today.
I'm not against trying new bulbs I've just used so few before. In my very first tank I tried an EVC 14k and an aquaconnect 14k. I'm torn between paying more for the Radiums while there are still some to be found and going with a cheaper bulb that could very well give me much better growth. At what cost is the question...

I personally do not like the blue look.....I have tried XM 10k's, Geisemann 14K's, Radiums and the phoenix 14K's on my M80 ballasts. (Keep in mind I do not run any supplemental actinics)
My preference is for the XM 10K's, they are superbright (I mean blindingly bright) and not as yellow as the XM 10K DE's on the same ballast, the geisemann are alright colourwise but not as bright......The radiums and phoenix look almost exactly the same colour to me and are really really blue

Just fired up the xm 10ks. After I recovered from the near blindness inducing brightness I discovered my aquarium was maybe 2 colours. Yellow and green yellow. Radiums are back in while I cry for the next week and raise/modify my canopy for these things.
