But you may spend days weeding through them. From the thread I linked to, I really think you might like the ATI combo something like this:
Aquablue
Procolor
Blue +
Aquablue
Procolor
Blue +
[front]
I have not tested this combo, but I did order the lamps, so I will test it soon. Mine will just have an additional blue+ and aquablue since I have a 8 lamp setup.
I currently am running:
Blue+
Aquablue
UVL aquasun
Aquablue
UVL aquasun
Blue+
Blue+
[front]
With this combo I got decent par, but the overall color is not spectacular. Reds and blues are muted, so I hope the procolors will help with that. I will let you know how they do. I would say this combo is close to a 14k with all lamps on, and an overall pink look. With just the outer lamps on (3 blue + and 1 aquablue) the greens really pop, but still not impressive. Maybe a 20k look, but no pop of the reds and blues.
Jin is also testing some KZ lamps so maybe he will chime in on those.
