I have two 250w halides over my grow out tank in small lumenarcs, running coralvue reeflux 10k bulbs. Both bulbs are the same age.
The dimable marinelux and coralvue non dimable ballasts are faily close in performance but, the marinelux produces slightly more PAR. I did not record the figures but Keith (Jacksok) was with me when I tested the output with his quantum meter.
This is obviously far from conclusive evidence; one of the ballasts or bulbs could be over or under performing. In an ideal world these results would need to be duplicated by some one else running the same kit.
Interesting non the less.

Marinelux dimable v Coralvue non dimable ballast = Marinelux produced more PAR

I'd go along with that although I can only vouch for the Marinelux. I replaced one of my standard Marinelux with a dimmable and turned out to pack more punch with the same bulb, to a point where I got some light shock on some of the corals!

Ahh yes, but how well do Marinelux ballasts work with 10k XM bulbs.

But I thought light travelled at 299,792,458 metres per second?
