I have a 3D Mag (thats what he had) and it isn't nearly as bright as my Streamlight Stinger (which is about 2C's I'd guess - its about 5 years old, and is rechargeable). The Fenix lights are supposed to be brighter than my Stinger too at about 1/4 the size!
That sounds about right (???)... and probably less than 1/4 the weight!
I have to run. I will check back later tonight. Got to get a few things done around my yard before dark and then to the gym.
Later.
