Works great for me
I bought this battery to use in my Streamlight ProTac 2L. I normally run surefire 123a batteries. Was tired of buying batteries over and over again. So I thought I would try the 16650 rechargable. Seem to be just as bright as to 123As. This flashlight requires a button top. A flat top did not work because there isn't a spring on positive side on the light. If u would like to save some money I'd give this a try.
