I got in on the beta test, so I've been running them for 2+ years now. There are several pictures from my tank(s) on the "Colored by LUX" page of the Luxdium website for reference. I absolutely love them. I won't run anything else at this point, as long as I can find used Primes and Hydras to convert!
I ran the "Optimized III" color mix with reduced white on my tanks for almost 2 years, but I've switched to running the "Ultra Blue" color mix on "Gold" pucks on all my tanks.
I chose the 470/420/450 LED layout for my AliE bars based on a conversation with Tim (luxdium) as I wanted fill light that would compliment my main lights without blowing out the wide blue band that I currently have.
