John,

I have Krill lights for markers and I have a glo-tube somewhere which I cant manage to operate. I'm also a big fan of arc either if it is their aaa or ls or a4. My entire point was that we take some specs for granted and when something happens and equipment fails it may cost you your life. I should not have to test my equipment when manual states that it can do specific task.

Reason I prefer 24/7 for my personal floatation device light is becasue it can work as a deck light, has a distress signal, warning signal, strobe mode and red light for night vision... it also has a "find me mode" so I can mark my gear and find it in the dark.
