I've often thought about this. Maybe the DL123A is more powerful for it's size?
Why don't we see flashlights using CR2 batteries? Maybe they just don't have the ommph to drive the lamps?
Good point. I'm sure someone will gather together some battery specs for you...

Ok here are the stats they are both 3v and the sizes are in mm
bat mA diameter height
AA 2800 14.3 50.5
123 1300 17.1 34.5
CR2 0750 15.6 27.0
2 of the CR2's wouldn't fint in the E1 body darn! A bit to long. They are just a bit thicker than an AA and quite a bit shorter. So if Surefire made an CR2 E2, it would run 1/2 as long. My guess about 25 minutes since it would be a big load on them. With the E2 there is a chance we will see a 100 lumen lamp, but if CR2's were used they couldn't take it.
It would be a cool little light though!

You can usually cram 2 CR2s in place of a single AA (with a little work). I did this with an Infinity task light. I agree, it ought to be more commonly done. The lower charge capacity of the CR2 compared to a 123 makes it more suited to LED lights, but that's the other side of the forum.

Clarification: I didn't mean to imply you shouldn't do this with a regular flashlight, but just that a super high power bulb like on a Surefire would give you an even lower runtime.
