Maratac on 10440 is the brightest...
I don't think so. I have a ITP A3 EOS, which is the same light engine:
The 1 meter throw lux readings I just got with my Amprobe LM631A, using the same 10440 battery in both lights, and measuring three times swapping the battery between them and averaging the results:
LD01................2113 lux
ITP A3 EOS.......1904 lux
Ceiling bounce:
LD01................112 lux
ITP A3 EOS........98 lux
I have a Maratac on the way, when it gets here I'll reconfirm these numbers with it, in case the highest mode on the ITP is lower; all the research I've done so far indicates that it is not, however.
