mileage and opinions are gonna vary quite a bit depending on what folks are selling or what they've spent a small fortune on and don't want to admit the downfalls. I know what works for me and don't have anything on the market. Green Cree Led is the ticket for anything a responsible shooter should be doing. The laser designators light up things good also but..... I have both cree and LD in green. The LD will concentrate more so seems to light things up better at distances (distances you have no business shooting when it is dark) but (yea another one), I have shined deer, our horses, fox, pigs, badger, and cats with the cree with no reaction. Turned it off and hit them with the LD and all were nervous/fidgety and some ran off. Even the horses spooked some and they know it's me coming. Also, if it's misty, foggy, or raining, forget the LD. The cheaper LD's don't work below 40-50 degrees. Last summer, folks on here and a couple other forums were drummin up the 250 +/- buck kill lights. I got a copy with remote pressure switch for 36 bucks and it is my favorite light.
This is a better deal than I got back then:
everything except some velcro
