I switched them all around to compare color and couldn't tell a difference other than the PFO wouldn't fire a new 12k. It fired a new 10k. The light in the middle is the one on a PFO, the ends are CV. All are 400se.
[edit] - I just read the above post - I ran this combo for a couple of months and it never really changed color, just barely less intense. I run the 10k on a PFO on a prop tank by itself and it looks white/blue. It's just pink next to the 12k.
