Through the kind courtesy of 4sevens is this Fenix E20 - 2AA light using Cree Q2, forward/tactical clicky and adjustable focus head.
Size -
Head -
head position: screwed down = tightest focus.
vs. Fenix L2D-Q5 both on NiMH (Kodak Pre-Charged)
the L2D is brighter - as it should be with a Q5 emitter and rated at 180 lumens (vs. the rated 109 lumens of the E20)
Since the head can be focussed - comparison with head set to widest/floodiest focus - vs. L2D-Q5 -
on widest/floodiest focus there is a hole in the middle.
vs. Fenix LD20 both on NiMH
this particular sample of the LD20 has the emitter out of the optimum position causing the notorious Cree dark halo to be shown more.
Again, not surprisingly, the LD20 is brighter as it has the same rating as the L2D.
Comparison with flood focus -
again the hole in the middle - I may not have backed out the head as much this time as the hole is not as emphasized as in the comparison with the L2D above.
vs. EagleTac P10A2 both on NiMH
pretty obvious that the EagleTac is brighter (rated at 220 lumens)
How about trying to optimize the focus for the smoothest beam?
vs. Fenix PD20 on primary CR123 Turbo
again not surprisingly the PD20 is brighter (also rated as 180 lumens) the wider hotspot of the E20 when focussed like this is very nice.....
of course YMMV for what is "optimum" - and I would also tend to use the tightest focus when outdoors.
