The UltraFire full function light is a premium flashlight in a compact package. It is small enough to keep in your pocket, and bright enough to use as a tactical light. Full brightness control allows this light to be used for self defense, or for close tasks that require less light. You get the best of both worlds, and as with all lithium powered lights, the batteries will maintain a charge in the cold or on the shelf. They are available in most stores that carry camera batteries. For the best value, buy a battery kit, which includes one lithium ion rechargeable battery. Don't forget a charger for the lithium battery, and a holster for safe storage.
