Just got my surefire E1B backup light today from batteryjunction, here are my quick beamshots and runtime test.
Lux readings at 1m: Hi 3900 lux, Low 232 lux (my L1 cree version: Hi 3380 lux, low 410 lux),
5m beamshots, left: E1B, right: L1 Cree
10m beamshots, left: E1B, right: L1 Cree
10m targets
Runtime graph (high level):
Show L1 runtime again for compare
I roughly estimated the total output is around 80 lum, same as my 65 lum L1.
Because I just got this light, not have comments right now, but one thing strange is the head bezel can be opened easily, I think it was not sealed, so my backup light is focusable, the throw can be changed from 3000 lux to 3600 lux.
E1B-low (5 lum) vs. ARC-P (5.5 lum)
02/25/08 update...............................................................
Got my #2 E1B, because my #1 E1B bezel was not sealed, I am not sure whether the light was in good focal point when I took shots, so I took new beamshots for my #2 E1B, and updated the shots and readings above.
