I really like the look of them, right now they reflectors are a bit higher (at 18" water to bottom of bulb and only for 5 hrs run time) but that's due to getting the corals use to the new light. The coloration is a lot better and that's without running the VHO's.
I ran a test with a M59 ballast and the look was duller than with the Vue ballast.
