Hi thanks for your quick reply. I really appreciate the advice you gave me it helped me to better understand some of the terminology used here. I believe from what you said the XPG2 would be what I'm wanting as this is for my weapon light and I want a really bright spot beam with some decent spill to see surrounding area, (a good defensive width) and a really good throw. Do you think that would be a good combo or is what i described even possible? Thank you and God Bless.
