“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. And it really works!
UPDATE: The 2000-hour design is based on a specific model flashlight. The manufacturer, Eveready, is introducing a new UPN (Universal Product Number) that employs the very same model number. And, yes, it is a bit confusing.
Performance of the new UPN has not yet been determined. Evaluation is underway and a new edition of this book will be issued (although not immediately; after all, 2000 hours of test time equates to nearly three months).
In the interim, the Kindle price for this book has been dropped to 99 cents. For the moment, you can still find brand new flashlights (in hardware stores, drug stores, farm supply stores, etc.) sporting the older UPN but you must take care to get the right thing. The photos and description in the book will guide you.
In view of these developments, may I suggest that, if you are at all interested in this project, it might be a good idea not to linger.
