I run my Seige on 3xAA using the Eneloop D-AA adapters. I'm not aware of any lanterns that run on 18650 or CR123, unless you were to put a diffuser over the bezel of a Solarforce L2 or Surefire 6P.
How much does this knock the output down? Or is it just less run time?
Thank you I think that's the solution to my problem, I found a 4 pack of adapters on battery junction for 9.95Just less run time. Output is identical.
Yes, it would.
