PAR 60 at 18" is not bad for FW, but not earth shattering. I am personally more interested in spread, I.e. will I have to use 2 fixtures (again) to cover a 18" wide tank. 24" wide tank.
Upgrading 10+ satellite+ fixtures that I got less then 6 months ago will be painful. Lets see some retail prices.
Yeah that's what I was thinking, but definitely better than the Sat+ on it's own. I run two Sat+ on a 40B and love it. I think for the money (minus things like FX lighting) t5HO would still be the way to go for intensity at those depths.
