This is my newest experiment. It is E1e with 700 Lumens. Yes, I have the AW 16340 protected cell, Malkoff P7, and EtoC adaptor. I currently use the P7 in my Pentagon PX1, but will soon add it to an E1B
With my cr123's it ran for 15 minutes with no drop in output.
At around 17/18 minutes the output droped and I stoped at 20 minutes.
Still very impressive runtime. Next, I will try it with my AW16340's.
