Also, the Jetbeam CLE and Civictor have different twisty mechanisms. The Jetbeam is the "crush your battery" type twisty which conducts electricity through the threads of the head (where the body is the female thread), like the Arc AAA. The Civictor is a more modern design which conducts electricity directly from the body to the PCB (the body is the male thread). The CiVic keeps the battery under constant spring tension, can accommodate battery length variations, and has a much more positive electrical contacts when on. The Civictor also goes 7 full turns from first thread engage to turn-on, while the CLE goes 5 (which isn't bad, BTW), meaning the CiVic thread has more mechanical support. The CiVic and the Fenix L0x lights all have this best-of-breed twisty design.
However, all that said, the CLE has the Cree and multi-levels, making it a more flexible and brighter light. I like 'em both.
