I got my EVC 14k's last night and took some pics. They are in my gallery, but don't represent what I see. The EVC's are defiantly more blue/purple than the radiums and cause the corals to floress more. They make the radiums look like 12k bulbs.
The thing that doesn't look right in the pics is the tank doesn't look neon blue like the pics suggest. I'll have to play with the white balance to see if I can get it to look more accurate. The bulbs to the eye look more blue than 400w 20k's, less blue than 250w 20k's.
The thing I was surprised by was the fact that they don't offset the xm10k's any more than the radiums. With 10k's and 20k's all on, the result was white, not white/blue.
