This is 2009, 120 lumens Surefire L4, it is the improved version, I think only the LED and circuit changed; besides, it looks exactly same as the previous version.



This New L4 has a SSC emitter installed, and there is a “B” printed on the head ahead the serial number.

Lux reading: 3750 lux

Beamshots: Old (100 lum) vs. New (120 lum)

5m: left, 100 lum L4; right, 120 lum L4


10m: left, 100 lum L4; right, 120 lum L4


Some observations:
Output: surefire still under estimated the output of this new L4, judged from the ceiling bounce test, the total output was identical to E2DL.

Beam: the beam pattern is very nice, very smooth with noticeable hotspot, and brighter wide spill. No artificial ring, no donut. Although the throw is improved in this new L4, I would think it’s still the wall of light.

Tint: Mine looks like cool white, if compared to other lights with warmer tint, it looks a little purplish, I like this tint, and at least it is not greenish.

Runtime: 120 vs. 100 lumens


The runtime has also been improved in this 120 lum version, however, the performance of using 14650 is not well, so the TW4 setup still works, jut not as bright as using two primary cells.

This new L4 has a great improvement compared to the previous version in output, beam pattern, and runtime. It has a nice flood beam combined with decent throw, this is good for either indoors or outdoors. However, if SF can make a 2-stages version, that would be better, at least, for me.

This new L4 also been well discussed in this thread, http://www.candlepowerforums.com/vb/...d.php?t=218892
