This is a more recent generation SureFire Backup. This one's from the generation when they were rating at 200 lumens on high. It's Flat Dark Earth, as you can see in the photo. It's got the two-stage momentary tailcap that does NOT click. Press lightly for low, press harder for high, and twist it to stay on in either position. It's been carried and used, but is in pretty good shape. This is one of the most useful lights I've seen SureFire produce, and I've had a number of these Backups over the years.
