MityLite™ 1900 Flashlight Unlike conventional flashlights that have a yellowish beam, the MityLite 1900 flashlight uses a hi-intensity Xenon lamp that produces a powerful, bright beam. Use this compact flashlight to cut through thick smoke, fog, and dust. It is submersible and comes with a twist-on shroud. The 1900 is ideal for any situation. Powered by 2 AAA alkaline cells.
