I don't know, but the new SC30 reportedly also has a similar problem.is there a revision that fixes this problem?
i emailed zebralight a little while back asking about the h61. they said eta about july/aug if i remember correctly.
The latest H60 version doesn't have the stainless ring around the lens. It has a recessed (spelling?) clicky, and a longer battery tube to accomodate protected batteries. See pictures at Zebralight homepage.
This may or may not work but small cracks in automobile windshields
can be hidden/fixed by a fluid kit they sell at car parts stores.
It penetrates the crack and hardens matching the refractive
index of the glass so the crack is mostly invisible.
Perhaps this could be used .
I still haven't heard anything from Zebralight either, I think I will use this option...
I just receive a message from zebralight customer service a time ago and anything else...
VERY BAD COSTUMER SERVICE...
