Best compact flashlight - Streamlight ProTac 1L-1AA Ultra-Compact Flashlight

If you are wondering, is this a good light? The answer is, Yes! The case is aluminum, it is lightweight, batteries are included, and there is a tiny loop hole to tie a cord or add a ring to.The three settings for High, Strobe, and Low are easy to use and consistent but it does take getting used to if you're used to other companies settings. The battery life is comparatively the best on the market for its size and lumen at 14hrs on low with a lithium CR123A or lithium AA; time is cut in half using a standard alkaline AA. A single lithium AA allows greater battery life putting the strobe function at 8 hours, high for 4 hours, and low for 14hrs. It's dual battery setup allows interchangeable use of a single AA or a single CR123A lithium battery without adding or removing components. It is definitely my favorite light having one in each color for my girlfriend and I. Do note, the CR123A battery included may have less than the allocated 10 years shelf life left as these items are shipped accordingly.
