I'm flustered. I love my Special Edition MkII Photon Freedom Micro light. It's a must-have EDC item for me. The problem is, I have now twice had to take the batteries out and use sand paper to get corrosion off the batteries due to moisture getting inside. Afterwards, it works fine. Have to buy new batteries now though, fine grit sandpaper still wearing the batteries out before the juice is used up.

This is due to my mode of carry, which I can't change. Around my neck hooked to my emergency meds. capsule, the light won't get damaged. It definitely will get damaged on my hip, in my pocket, or on my keychain of many work keys, due to my work. I don't always have a shirt pocket.

Ok, so Sasquatch sweats too much on his Photon. What is the solution? Can I moisture proof the light with something? This has been the perfect carry mode for me with this light until now. I never know its there until I need it.
