I wish I'd gone the extra $12.00 and gotten the Fenix L2D Premium, but I'm happy with the Fenix L2D CE. I probably would have bought the Premium had I noticed it. The Fenix Store Site is a little whack to navigate.

The Fenix has taken the place of my Pelican M6 2330, which is now relegated to a backup light for similar reasons as your Surefire.
