I have a LED Surefire, that has high and low, takes one CR123, and is black. I bought it used, and love the light, but I don't know what model it is, it just says "BACKUP" on it. I also have a A2 Aviator, that I love the finish on. Does, or did Surefire make a light, that is LED, takes one battery, preferably has high/low, and has the hard greenish finish and knurlling like the A2?
