In case you are born in the 80s like me, your idea of a flashlight is a device with old fashioned batteries which, when fully functioning, would light your path for a few meters ahead. Fast forward to 2020 and the era of super-powerful led lights and rechargeable batteries and boom; you are in for a surprise.
One problem is however the reliability and price. You are in for a disappointment if you buy your led flashlight online from Aliexpress or god forbid Banggood (now better known as Bangs**t) and it stops working after a couple of weeks. This is why I was delighted to see the first Finnish designed, and CE certified Led Super-flashlights from Kaari.
