"The Amazing 2000-Hour Flashlight" shows how to add a 30-cent resistor to a $5 flashlight and create a light that produces useful illumination for 2000 hours on the same battery. Detailed instructions. 54 illustrations. A half-hour project. No soldering required The standard for "useful light" is defined and various lights compared to it. Brand names and part numbers and where to buy them (Home Depot, Radio Shack, etc.) are all identified. Related topics include bypassing the resistor, rechargeable batteries, and how to substitute other battery sizes. "Don't be afraid of the dark," we chide our children. "Don't be a 'fraidy cat." Really? An underground parking garage in a blackout is intimidating. Getting the right prescription out of the medicine closet in the dark will make a 'fraidy cat out of anybody. Delivering a baby in the dark is life-and-death. But you can take control. For a very small sum you can have a flashlight that runs for weeks at a time on the same battery. What do they say? Do it now while it's fresh in your mind. Two free bonuses are included: (1) a chapter from "Lanterns, Lamps & Candles" (a different book on lighting by the same author) and (2) a chapter from "The Prepper's Guide to Food Storage" by Gaye Levy (proprietor of the Web site Backdoor Survival).
