have you looked at the giesemann megachrome bulbs?
according to sanjays test, even the coral (14.5k but looks white) is a par monster. im waiting on on delivery on mine, will give you an update when i get it.
some people dont like the pure white color it gives, but all seem to agree that it does color up corals nicely as well as stimulate fast growth.
the bulb is also said not to shift in deviate in color by more than 3% in 3800 hours! so even if im not crazy about it, its a great back up bulb to have that will feed the corals well.

I ran a de 250w xm 20k on a pfo pendant and reflector over my 20gal for close to a year. I liked the color though it is fairly blue. I don't have that tank anymore because I'm studying out of the country but upon returning here shortly I plan to set up the same setup.

I am considering getting a 250w Helios 20k DE. Apparently they are about the same color as a radium... I personally think there is no better way to get good colors than with 20k lighting. The problem is its low PAR and thus the growth is less. However, I plan on using a set of 20k with 4x54w T5s as well (probably 2xB+, 2xUVL SA). If its too blue I can just swap out 1 or 2 of the actinics for an Aquablue bulb to brighten things up a bit.
