Hello everyone, I am a noob here with a couple of questions. I have a victorinox 2 c-cell flashlight I was given as a gift. It looks well made and I like the larger size. I was wondering if there are any drop-in led replacements that would fit this light. The unit in it now is 29mm wide and 32 mm long. My other question is will 2 c cell batteries be enough to power a more powerful drop in unit? I was looking for something maybe around 80-100 lumens. Thanks
