If you're looking for the best flashlight or best torch, the rise of LED has changed everything - and the market is flushed with LED flashlights from top brands such as Maglite and Fenix.
The humble white LED (Light Emitting Diode) is one of the truly great inventions of the past twenty years. Although it was originally invented in 1927, the concept lay dormant until, in 1993, Japanese electronics professor Shuji Nakamura pulled off a doozy by developing the modern white LED we see today in every torch in every land.
LEDs have truly shaken up the flashlight industry. There’s no more of that dimming light malarky after just 60 minutes of use. Today’s LED’s consume about 12% of the energy used by halogen and filament bulbs to emit the same amount of light. This means an average LED torch will go on burning for hours, if not days, at a time. And, what’s more, it has a life span of around 50 years, which is more than one can say for the average filament bulb.
An LED’s light intensity is calculated in Lumens, a unit of measurement used to quantify the amount of brightness emitted by a light source. As an example, a wax candle generates 13 lumens, while that old 100 watt filament bulb you have in your living room generates around 1,200 lumens. But all you need to know is that the more Lumens a torch has, the brighter it’ll be.
