I bought a L2D a few years back.
I selected this over other high intensity LED lights using the following criteria:
1) It was priced lower than Surefire, STreamlight, etc.
2) It has one of the "better" LEDs out there at the time.
3) It took standard AA batteries.
4) The reviews were very positive from several sources.
FENIX is a Chinese light.
Well..............the other day it flaked out. i found the warranty had expired when I looked into service/replacement so I took things apart, did some maintenance, troubleshooting, etc.
Turns out it was the endcap switch; and underneath all of the seals and rubber boots was an Omron PCB switch.
I emailed the factory; asking them if they could provide a spec for the switch so I could find one (and de-solder/replace it).
They referred the request to a domestic dealer who sent me a brand new switch "assembly" free of charge.
Thought I'd share a "positive" for those looking for something like this.
