It really depends on what you're doing...Scott M:I've never been in the water with my LC, how do you like it?
If I had my way, I'd spring for a 10w HID can light and be done with it....but as it stands, I don't have the $$.
The LC is a PITA to do anything with if it is in your hand (unlike with a goodman handle). I'm going to modify (when I get the time) the LC to be more useful in this regard. It also doesn't ride real well anywhere while it's off. I tend to tuck it under my arm with a lanyard around my wrist. However, it works well for light and signalling while diving...it's a cheap (especially since I got it used) alternative to a can light...and yeah, I accept that.
