The SureFire Digital Fusion A2 Aviator -
Digitally regulated incandescent bulb ~60 Lumens constant output for 60 minutes. With a 3 LEDs mounted within the reflector for useful "navigational", reading, etc output.
The A2 has a two stage pressure switch LockOut TailCap -
Press it gently to light up the 3 LEDs, or rotate the TailCap for constant LED output.
Press it harder to light up the main beam or rotate the TailCap on for constant output.
The A2 is roughly the same size as the current E2e - That's tiny. The A2 gives you the ability to have brilliant white light and LED output from a single flashlight that is perfect for EDC.
The latest proto-type of the A2 was shown at the NRA Show / Conference 2002.
Reference the following photo showing [top to bottom] the E2e, the 2nd Gen. A2, the 1st Gen. A2, and the M2.

It's amazing that SureFire have managed to fit the A2 into flashlight number 1 (shown at the SHOT Show 2002) - Then, at the NRA Show 2002, a smaller A2 (number 2) is shown!!
The LEDs will be available in white, red, blue or IR.
The output will be similar to the E2e but at a higher colour temperature (brilliant white), and will remain so for the runtime of the batteries (two x SF123A).
Some of the "Digital" SureFires due for release this year feature constant output regulated incandescent bulbs. With the M2D & C2D, the output will switch to about 20% of full for the final 10 minutes of the runtime allowing you to not only have warning that the batteries are almost dead, but also enough light to locate a backup SureFire or spares carrier.
While I was out with PK in Vegas during the SHOT Show 2002, the A2 proto-type was his EDC. I got to have a try and it is on my wish list to be sure!
Digital Fusion is significant.
