| Highly recommend at 10W or an 18W HID - best piece of dive gear you will ever buy. You spend all that time and money to go underwater so you might as well see something!
I have both 10 & 18W Halcyon heads and unless I'm diving in the tropics the 18W will be with me. Even in the tropics a 10W will improve your dive - you'll see a lot more details and colours.
Only trick is not to blind your buddy (or self)
