Today everyone knows what a flashlight is. It is not a big deal if you own one. However in the 19th century that was not the case. Thanks to David Misell around the end of the 19th and the beginning of the 20th century a small battery charged devices were introduced which could generate light in a short period. It was a real revelation. Preceding the flashlight and necessary condition to be developed was the battery with a dry cell. These batteries as we all know today use paste electrolyte therefore they are much safer than any other alternative.

Many of the current electronics are possible due to this invention. Comparing a flashlight and a lantern would be comparing apples to oranges. They serve the same purpose, but the brightness the compatibility and many other characteristics out waver the other.
The first manufactured light bulbs were paper tubes.

The light bulb at the end of the handle was paired up with a reflector, and all of this was powered by a heavy D battery with the positive and negative charge at each end. The first flashlights were provided to the police forces. They all agreed it was one of the best gadgets at the time. As time passed, because of the great interest, around the 1920s a few different types had been mass produced.

The first one was made so that you can place it on a flat surface and attend to some additional work without holding it. One of the most popular was the pocket size one. It was convenient when you are doing any work nearby. The last one is a large reflector which was most commonly used by farmers, search parties or just illuminating an object in the far distance.

The flashlight business was growing and expanding exponentially. Their popularity went global. First, it was only the US market than China and later all over the world.

The revenues of the flashlights could be matched up with any other home appliance. Incandescent lights were the only ones used at the beginning for a very long time. Still, they vary depending on how many lumens they can produce.

Going from pocket lamp to a reflector the lumens can be measured from 1 to around 200. Some of them tried halogen gas filled bulbs, but they proved inefficient. Recently diode lights are widely used. Most of us know them as LED. It took considerably some time for them to reinvent these views and make them high-powered. The result was worth the wait.

They are convincingly better than incandescent lamps. In comparison, incandescent light per watt can produce 10 lumens whereas the LED light can produce 100 lumens. Not to mention the battery life. The latter ones use less power and are less fragile. This is the reason why they are not changeable like the bright ones. These are not the only two options. There are HID lamps.

The abbreviation stands for high-intensity discharge. They are better than the incandescent lights though much more expensive because of the intricate system that makes them work. For now, we will stick to LED flashlights until the next best thing.
