Very tough one to call.
I have the F2 running on 2 x RCR123's...its the brighter version..when fully charged it is bright..huge bright spill... due to the shallow E2e/D reflector, but still with a noteable hotspot. very usefull for EDC usage,...lets you see the big ( close up ) picture without panning around.
I'd roughly guestimate a good 70 + ( surefire syle rated ) Lumens...Maybee more...for an hour +...Happy days
but its hard to rate against the TL3 lamp in the E2D at the beam shape is different as is the colour temp. But as its so white the F2 looks as hot, but outside the TL3 throws more and shows more colours but seems yellower and thus appears dimmish in the spill...if that makes sence.
TL3 Five mega socket for outside short lightweight EDC...koala/yclo F2 for runtime, and close up work
The other big mags in the picture are 4000 ++++???? Loads of lumens :devil:...but they don't fit in your pocket ( exept the 2D ) but that only runs for 8 minutes. :duh2:
