EMERGENCY-FLASHLIGHT

No matter where you live or work, you would have surely experienced a power outage in your home or office some time or the other. Power outages can often cause panic and chaos if there’s no other lighting source available around. The solution is to use a lighting source which does not depend on your local power supply authority and can be switched on any time you want lighting. Keeping an emergency flashlight handy is the answer to handle a power outage without losing your peace of mind.

So, what exactly is an emergency flashlight? In technical terms, it’s a portable electric source of light which emits light using an incandescent light bulb or LEDs. Flashlights come in variety of designs, sizes and shapes. The most common design uses a lens which is shaped to provide a strong beam of light.

Besides the lens, an emergency flashlight also contains a transparent window which helps to protect it from any accidental damage.

The lighting comes from a source of power which is either a battery or electric cells. Last but not the least, there’s a switch which helps you put the flashlight off and switch it on only when you need to.

As shown above, most of the emergency flashlights are handheld and pretty easy to operate. Campers and miners often use emergency flashlights which are in-built into their helmets or other protective headgear.

Professional bicyclists and sportsmen also often use such flashlights when embarking a long ride especially during wee hours of the morning or late at night.

Not all emergency flashlights use electric batteries, if you are a green energy freak, you’ll be able to find ones which run on solar energy and are environment friendly.
