Led Flashlights: Everything You Need To Know

This is a post written by our collaborator C_DOS of EcologyMagnet about the world of LED flashlights.

Almost whenever a person discovers that LED flashlightsform a hobby by themselves, they are missed, so throughout this entry I will try to explain the reasons for this and the main features of this lighting system.

In general we all know the technology that uses LED lighting and its main features: high efficiency, high emitter LED life, low consumption, etc; But it is hard to imagine that a relatively compact and economical LED flashlight can double the light output of a car thanks to this system.

To give you the idea, a traditional quality incandescent flashlight, with two D batteries (the typical Maglite 2D), round 19 lumens, while the usual LED flashlights ( always talking about powerful flashlights, not the typical one that costs a couple of Euros with dozens of LEDs ) are usually around 1000 lumens, and in the case of those using multiple powerful LEDs, it is not difficult to reach about 4000 lumens and multiply by 200 the power of an incandescent flashlight we usually have at home.

I think after seeing this comparative, it is surprising to see the difference of light emitted between an LED flashlight and an incandescent or even the long lights of a car, is one of the main reasons that attracts so many people to this Hobby and turns the flashlights LED in an excellent working tool in some cases.

Components Of LED Flashlights

Body

In the case of LED flashlights, one of the significant differences is that its body is usually Aluminum and in some cases Steel or Titanium, this provides a resistance and feeling of quality far superior to the incandescent torches that are usually plastic.

Led

As we have said its main characteristics are high efficiency, high life and low consumption; But in the case of the lanterns we must add to these characteristics the power, use high power LEDs that have no comparison with the LEDS we usually see in flashlights € 1, the main brands with Cree and Seoul.

Thanks to this technology we can forget about fused light bulbs, have greater autonomy and greater power of illumination.

Driver

The driver is a small circuit that regulates the intensity that the LED receives, besides it is usual that it gives us different modes with different powers, blinks, SOS in Morse, beacon functions… also in some cases we can warn of the state of Thebatteries and can even be configured by a computer using a USB cable.

Example Of A Flashlight With USB Port

Batteries

As a general rule we can find from LED flashlights that use batteries to some that use lithium batteries, in the latter case usually have a voltage of 3.7V, an example of nomenclature would be as follows:

18650: 18mm wide and 65mm long, the final 0 indicates that it is cylindrical.

The most common ones are: 10440 (AAA battery format), 16340, 14500 (AA battery format), 18650 and 26650.

The main advantage of lithium batteries is that they providehigher voltage and higher current ratings than a conventional battery.

Conclusions

The first sensation when seeing an LED flashlight , is always the same, a big surprise , as a rule they are extremely powerful, emit a white light and their finishes in metal, as well as the modes are usually for many a novelty in the world of Lanterns, so far, I have never seen anyone indifferent, and when they consult us to buy a flashlight or try one of ours, we will know that they will have a strong impression.

These tools are often used in different uses, including sports, I use them on electric bikes when I go out at night and generate such interest, it is common for people to joke or make comments when crossing with them.

As I say, if you do not want to end up with a shelf full of flashlights, you’d better never try an LED flashlight, there are too many who just bought one and ended up with a case full of them.

Who could resist a gadget that illuminates more than a car, has different modes, can be configured by a computer, is efficient and is one of the greatest revolutions in energy saving…
