Ray, yes the HPL is bigger, but it is also 40 dollars cheaper and it's BRAND NEW! It now resides on the left side rail. It allowes me to do the momentary and constant on and strobe with my thumb.

NO, it's not the one I wanted, but like I said at 40 less I can deal with it. And boy does it throw a long beam! Not real sure about the side spill light yet, haven't had a chance to use it in a black out situation, but I might turn off the lights in the office and see what happens.
