With a maximum light output of 120 lumens, the SureFire L4 is bright enough to qualify for tactical use.

The SureFire L4 LED flashlight also features digital current regulation circuitry to match the LED's current requirements with the battery's output to maintain a more consistent level of light output for the useable life of the batteries (as opposed to unregulated flashlights, which are subject to a steady decline in light intensity beginning shortly after activation).

from CT gives it a 4 and says..
A.J. is spot on... The L4 is good for illuminating large areas at near ranges. It has a constant 100 lumens for about an hour but is useful an hour or so after. Your need for wide area illumination is really the deciding factor on this one.

This is my preferred light for turning on the generator when the power goes out. The wide angle is useful indoors - I don't need to swing the light around (it really just light up one general direction). I don't use it outside much - not enough throw. Mine has a decent tint for an LED but obviously can't compare to an incandescent.

Surefire ruggedness (best in the industry).

from Erie, PA gives it a 3.5 and says..
The build quality of the L4 is all Surefire. Solidly built with a pocket clip and O ring protection at both the head and tailcap with SureFire's no nonesense warranty. Nothing more needs to be said about that.

Switching is done via a forward clicky with both momentary and lock out capabilities. The switch has a good feel and feedback during use, and the momentary function is easily access and maintained.

Output is in the form of a modest hot spot and wide bright spill. The L4 is all about flood lighting. It will throw a fair distance, but it really is designed for use as a wide area light.

The body of the L4 does help to dissipate the heat generated by the Lux V emitter, so the body will become noticeably warm during use. The head itself may become quite warm and carries a "hot surface" warning label.

The L4 will produce about 100 lumens of light for one hour before it falls out of regulation. That's aggressive as far as battery consumption, but there is a fairly long peiod of diminishing output that is still very useful and provides plenty of time to find replacement batteries before the light goes dark. My light has a nice white tint, but it should be noted that tints on the Lux V emitter are variable.

All in all, a very useful light backed by an excellent warranty that means you will never have to replace this light unless you want to.
