I have used the C8 LED on mabe half a dozen dives in either low light or no light conditions, and it is superb. my buddy has an incan pelican 4c model and it blows it away. it is really floody but powerful enough to throw far (for a dive light) I used it last night on a dive (no ambient light) and was gain very pleased. the handle is very ergonomic (pistol grip) and comes with a fairly good lanyard that sinches up around your wrist. though a retractor might be preffered. I really cant say anything bad about this light. If you get it you wont be dissapointed.
