Re: l1 Bright enough?
That's right - there's two-stage switching, and there's dual output switching.
They are very different User Interfaces.
The two-stage push button pressure switch allows the user to press for low output and press harder for high output. The TailCap can be rotated for either low, or high output mode constant-on. When the low output mode is constant-on the user can still press the push button for high output.
The TailCap can be unscrewed from the body to disable first the high output, and then the low output, locking out the flashlight.
The dual output UI uses a standard Clickie constant-on TailCap push button switch. One clicks the light on and off and on again to toggle between output modes.
The E1B just has a standard clicky tailcap. The two stage part is due to electronics in the head. I think the L1, L2 and A2 are the only Surefire lights with 2 stage tailcaps.
Also the Kroma, and the 10X - the one that started it all.
