I have one of those as well and it is as bright as my surefire, thats a great flashlight for the money! If you end up getting addicted to the lithium lights as I have make sure you buy lots of backup batteries they start getting dim after about 30 minutes of continuous use. I found a 12v lithium battery (uses 4 of those lithium batteries vs. 2) powered light in the sportsman guide catalog for $50!!
Don't gouge me bro!
