Just received my Production version of FF3 in the mail today:
Left - Production FF3; Right - Pre-production FF3
I got the production version to see if there's any improvements made over the pre-production unit. Ansolutely not!
1. Ballast noise. It's as noisy as my pre-production unit before the mod, comparing the two side by side, my mod cut the noise down more than half.
2. Components. I looked everywhere, can not see any difference what's soever.
Visually: no difference can be observed.
Production Unit -
Ceiling bounce 465/Throw 215,000 lux@ 1 meter
Pre-production unit -
ceiling bounce 505/Throw 225 lux@ 1 meter.
The pre-production unit has slightly better performance but that could simply be light-to-light component variations or minor variation in focus.
I put the production unit FS on CPFMP, got it for review, never intended to keep two:
