I just noticed that the KL4 is no longer listed at SF.com. I guess it should be no surprise as the M600A Scout Light was pulled a few weeks (?) ago . The L4's days are numbered.
I still have my first KL4, the first SureFire LED I ever owned. It's on a VG FB1 body (a la TW4). It served me well as a EDC for over a year. And in the winter, it served double duty as a hand warmer. Yes, it got very warm quickly, and much of the time it was more light than what was needed. Still, nothing quite matches its "wall of light" output. We have reached the end of an era...
