This has been an informative thread for me. First I might be scared of the dark.

Second, I found a Fenix dealer today and got to look at their lights. They were out of the PD35 but I will pick one up once they get one in. I did notice that the 680 lumen light was listed at 18225 CD which explains a lot to me after reelman's answer to candela vs lumen.

Fenix does offer pressure switches, batteries, chargers and a mount. The dealer said he's been selling them about 2 years and his Surefire sales have ceased and his Streamlight sales are hurting.

Thanks Blue, I needed another light...
