Everyone needs a good tactical light. This one has a long lasting (like forever) LED bulb that puts out 120 lumens (a whole lot) of light. This works on two Lithium CR123 Batteries with a shelf life of 10 years. This light will be there when you need it. It has an aluminum construction, a belt clip and anti roll design. It can be used as an impact device and distractor. Tactical lights are a must for the armed citizen. Spend a little extra and get an LED. We have found this one to be a good value. We are offering it well under retail. Good quality LED lights are not liked the cheap stuff you see everywhere. These are good lights. This retails for $110, we are offering it closer to our price.
