Mankind’s innate fear of the dark was squelched in 1898 when Joshua Lionel Cowen, owner of the American Electrical Novelty and Manufacturing Company, came up with an idea for a decorative light fixture for a flower pot that ran on a dry-cell battery. When Conrad Hubert took over the company, he developed the idea and patented the very first flashlight in 1899. After that, Hubert changed the company’s name to American Eveready Battery Company. The flashlight was born, so called because the carbon-filament bulbs needed frequent “rests” in order to work properly, therefore, the user could only flash the light briefly.
Choosing a Flashlight
There are a host of variables you’ll need to understand in order to properly buy a flashlight that will suit your needs, from the battery size and case material to the bulb type and candlepower. Cheap flashlights can be had from any grocery store, but you usually get what you pay for. In order for a flashlight to last you the rest of your life, take care to find one that is made of a robust material, like anodized aluminum, with a common battery type (CR123, AA, or AAA) or rechargeable. Comparing one flashlight to another by lumens alone is misleading; instead, focus on how the light is used. Is it focused in a tight area or diffused over a wide space? Lithium-ion batteries do better in the cold but they cost more, while cree XR-E and Luxeon LEDs are more efficient. Is the reflector textured or smooth; smooth reflectors have a tight beam while textured ones spread out the beam.
Good flashlights can be expensive, so make sure you understand your basic needs. Perhaps it is better to buy two flashlights for different but specialized purposes than one general all-purpose flashlight.
