Okay, I know flashlights might seem like a less-than-noteworthy topic, but just think about it for a second. In a nighttime emergency, what's the first thing even before food, water or shelter that you'll need? Unless you're a cat or some other nocturnal animal, you'll need light. In an earthquake, it'll ensure you get to a safe place quickly, if you're lost on a hike, you'll be able to see the ground and avoid tripping or injury, if you're in a dark parking lot, it'll help you find your car.
Whatever the case, it's a major bummer when you're flashlight runs out of batteries. It's also not fun or practical to lug around a huge light just because it's brighter than a small one. If you’re a backpacker, for instance, you know every ounce that you pack has to count. If you’re a working woman, you know you’d be safer if you had some illumination walking to your car at night, but it would be nice if that flashlight fit in your handbag.
Luckily, LED technology has improved the flashlight game for everyone, whether you are a city-dweller or a back-woods camper. Not only are LED flashlights smaller and more lightweight than most other flashlights on the market, they also require so little power to run, that you’ll rarely have to replace the batteries. In fact, some LED flashlights are powered simply by shaking the flaghlight itself. These types of flashlights rely on small, replaceable batteries for the first 12 hours of continual light. Once the batteries are exhausted, the user can shake the flashlight, which causes a magnet to pass through a metal coil and induces an electric volt to power the LED light bulb. You only have to shake the light for ten or fifteen seconds to get bright light for three minutes. It’s just another way LEDs are making our world a safer, brighter, happier place!
