This thread is so stuffed full of jargon I can't make much sense of the good information contained within.
Is there an idiot's guide that just says "Here is the light, recharger, batteries, mount, total price and where to order it all for under $50ish?"
I know that would make it a whole lot easier, besides it appears you have all done tons of work figuring it all out, why should I do tons of work figuring out what you decided.
