National Flashlight Day

Bring out your flashlights on National Flashlight Day to thank everyone involved in their creation! The product saves us in the darkest times, illuminates the path, helps to see what is hidden under the cover of night. Perhaps there is such an attribute in every family!


The flashlight era began in 1887. Scientist and inventor Carl Gassner of German origin received a patent for the created zinc battery. This was a real breakthrough, however, initially it was not clear where the best way to use it. The question was resolved by itself: Gassner remembered another wonderful invention – an electric incandescent lamp. By combining two products in one, you get an electric flashlight, a real helper in everyday life.

Today they are not as popular as they used to be. The flashlight is easy to turn on with one touch in our smartphones – it is always at hand. But a classic product is considered more reliable: the phone can be discharged at the most inopportune moment, and a flashlight with new batteries will work for a very long time. There are tactical, emergency, railway, tourist and other devices. Learn more about species on National Day!
