I've never seen beam shots. The A2 has a dual position tail switch. Push or screw in a bit and you get the three LED to light up. Push or screw in a little further and you get the incandescent to light up. The LED's have simple resistive circuits (SMD resistors on their PCB). The incandescent has a digitally regulated driver (constant voltage I presume). I believe SureFire has looked at a few incandescent lamps in terms of power but I don't know what LA rating will come standard or if there will be LOLA and HOLA options. As far as a picture, the one below has been shared on various posts and I grabbed a copy after I realized that PK's library was no longer available :-(
