Hetland - I've seen a lot of your pictures, which are great by the way, so I know you know a thing or two about lights.
Thanks for your advice!! I have a friend who is going to change out the light of whatever light I get to an led. I don't know if he can change the battery type or not (if anyone knows how it would be him). I've spent a lot of money on gear the last couple of months and am still unsure if I will continue with diving, so I'm really wanting to rig up a light that will work for shore dives as cheap as possible.
Any chance you're coming out on sunday? I'd love to finally meet you and put a face with your screen name.
