Radion TIR Wide Angle Lens Questions

[MockandRoll]

I have a Reefer 170 with 1 radion 3G Pro (33%, 10 hrs, 12" above water) and 4 24W T5s (3-4 Hours). I am switching to wide angle lens. How much of an increase in percentage should I turn up the radions after switching? I was thinking 2-3%.

I think there is more than a 2%-3% PAR loss. Here is a thread where someone measured PAR before and after, and to match they went from 45% power to 75% power after adding the lenses:
