Can anyone confirm whether a Sola series light (I've a Sola 600) has sucessfully been used in the 120m range?

I too it on a dive the other day and had a few issues getting it to turn on at depth. Now I was a bit scattered at the beginning of the dive when I hit the bottom, so happy to call it user error on this one but wanted to get confirmation.

From memory I seemed to have issues with the slide mechanism that turns the light on, almost as if the spring was working correctly and I had to pull/push the slide button manually. As I came up to shallower water the unit works perfectly, but so was my head.

It did not flood, implode, etc... after a 20min bottom time.
