Problem with Zebra in the cold

[CathastrophiX]

Before I cut the tailcap spring on my H60 ("old version") I started having problems at around 5°F, but now it works at -13°F with no problem.

Nobody has realized that his problem simply may be that his light may be defective. Loose solder joint, flaky component, etc.

I am sure it is getting cold and shrinking and loosing contact somewhere.

I am needing to know if there is a fix for this? Or if the new generation H60 handle the cold any better.

This topic started drifting when people thought that the battery was the problem.
Now we all know that it is not.
