I got my advice from a helpful CPF'er.
SMACK IT HARD, and you will be able to push it out the rear. it is a press fit plastic cylinder, and it will come out. as for a result, I used the led from the photon with no resistor, thinking that 2x 2032 @3V each is more than 3AAAA @1.5V each. I cant quantify the results past the point of saying it works. the led from the Stylus had corrosion on one of the legs, making the light flicker.
today I made a 1x17500 E series body for fun. it was easy. time to start modding/building someserious lights!
