This is now decades that the flashlights are part of our daily lives. We use them on many occasions. But with the advance of technology, the choice has become more laborious. How to choose a lamp torch today in 2018? On what criteria to build? Follow the guide.
As you can see in specialty stores and on the internet, there are different types of flashlights on the market.
First of all, there are conventional lamps that don't have options: they are sufficient to light and that's it. Generally, these are templates that are very powerful and reliable. However, sometimes that some models allow you to adjust the intensity of the beam of light, no more.
Then, there is the head torch lamps. As its name suggests, this headlamp to those who wish to have extra lighting while having both hands free. They are used to do cycling, biking, trekking or running. Many professionals also use these models: mechanics, cavers, the miners, not to mention the electronic engineers. In most cases, the head torch lamps are water-tight and resistant to dust, to allow use under extreme conditions.
Finally, there is the tactical lamps. Initially, they were intended for the elements of the security forces in the United States. The army, the police and other professionals were using this type of flashlight to neutralize an individual problems more easily. The operation of this lamp is simple: among the many lighting modes, there are blind strobe effect for a while, preventing further progress. With the upsurge of insecurity, these tactical lamps became popular. Today, many households provide it in order to defend against the attacks and burglaries.
There are several cases where the use of a flashlight is needed. This will allow you to choose your lamp, according to your needs.
First, there is the professional use. For example, it is the case of the professional mechanics who use strobe flashlights, or even the security guards, the elements of the security forces or even firefighters who use a flashlight throughout their interventions Nocturnes. Spelunkers and underground workers are also required to use flashlights throughout their activities in the caves.
Then there is the domestic use: to go to the power distribution panel when a fuse to fetch something in the cellar or simply when there is a power cut.
Finally, there is the use for leisure. For example, there are people who practice hunting at night, others need a flashlight when they leave camp or on vacation because it is not always easy to find a power source when you're travelling. The flashlight is also useful for those who practice nightly sports activities: mountain biking, trekking, hiking, scuba diving, mountain climbing, etc.
We tend to think that the maximum power that we have, is better. And yet, it is important to well to address the issue. The reason is simple: more light output is important and more energy demand will be great. As you can see, a powerful lamp will be gourmet and autonomy will be limited. After, everything depends on the needs of the lamp. For example, people who go mountain or hike need lamps to autonomy, whereas the vigilantes and security forces need more powerful lamps.
Also, beware of misleading advertising that can do some brands as the power of the flashlights. Better a lamp which is actually 500 lumens, rather than one which announces 12 000 and yet, that will be less effective than anticipated. There are a few tips to recognize these come-ons. For example, know that a lamp has only 12 led and who claim to give more than 10 000 lumens. This will mean that each led cell shall provide 1 000 lumens: to give such power, he had important batteries and not some aaa batteries. In addition, they are offered less than 10 euros, if doubly wary.
In some cases, the use of the flashlight is that punctual: when electricity is cut off for example. The battery life isn't important. On the other hand, some uses require a substantial autonomy: when we go on hiking, camping, etc. This is the reason why users are very fussy about this criterion when they want to buy a flashlight camping for example.
Please know that this autonomy depends on the type of technology used. Bulbs lamps have a longer battery life. On the other hand, the intensity of the light beam will decrease as the battery or battery discharge. For example, the intensity of the beam will vary from 500 to 70 lumen, during the unloading of the battery or aa batteries.
As for the flashlight led, it has usually a system of regulation. The principle is simple: even if the battery runs down little by little, the control system will ensure that the beam remains powerful. Then comes a breaking point where the lamp will turn off suddenly. Some more advanced lamps are fitted with a witness who warn that breaking point approach, allowing you to anticipate and get a new battery or a lamp substitution.
Scope and diameter of lighting
Often, we can read "range up to 400 meters" on the boxes of the flashlights in the trade. And yet, we should not be tempted to. It is true that a beam can reach several hundred metres, but at what light intensity? You will understand that it is a marketing argument for the long range of the torch will be of no use if the beam is not powerful enough. As much focus on other criteria such as autonomy, the power light or other.
It is also often question of diameter of lighting. Generally, this criterion is little put forward by brands. And yet, it is the effectiveness of the flashlight. Whether it's classic lamps or led Pocket lamps, there will be always a point focal (or point of impact) and a flood called Halo. Everything depends on your needs: do you need of more flood or rather a focal point more important? There are some models which are adjustable, which will be able to accommodate your various uses.
Size, weight and ergonomics of the lamp
Ergonomics is a very important criterion when choosing a flashlight. Indeed, it will be inconvenient to carry around a lamp whose size is similar to a bottle of water while she is supposed to be a "flashlight" and so fit into a pocket. Research of the size and the weight minimum is not always a good thing but logically this requires a reduction in efficiency. Indeed, having a light lamp and small size means to cut back on the autonomy and / or on the power output.
Moreover, there are also small lamps tend to heat faster, especially if it is not a good led flashlight. Indeed, the body of the lamp is small and more heat has difficulties to dissipate.
Before you choose the lamp to the smallest or largest format, then think about your priorities!
There are many standards that govern the flashlights like other products. For example, there is the standard anti-corrosion: it is mostly observed in lamps for use in outdoor environment (sport, leisure, etc.)
There is also the standard ATEX, which caters mostly to professional uses. This standard focuses on the lamps used in areas where an explosive atmosphere can form at any time. These are firefighters, emergency services and other intervention forces which often lights torch following this standard.
The best known and most widespread standard, is the standard IPX. More precisely, it is a standard that defines the level of tightness to rain. It should be noted however that this seal will not allow for as much to take the lamp to go diving. For example, a lamp to IPX-8 standard will be waterproof even falling to a depth of two meters, but for a moment very short.
With or without security?
It's a question being asked of consumers: should I choose the models provided with warranty or not? Of course, the flashlights that are guaranteed are more costly. However, they allow can be to obtain compensation from the manufacturer if the lamp never came to know a problem.
It remains then to focus on the conditions of guarantee. Indeed, it is well and good to opt for a guaranteed model, but it does practically nothing when a clause stipulates that guaranteed such plays in the event of a manufacturing defect.
Last but not least: the price
Lastly, it must focus on the price. It is important to consider this last parameter because the highest cited criteria are more important than the other. By blindly choosing a flashlight by looking at the lowest price, you may fall on a model that does not meet your expectations. Note While there are lamps less than 10 euros, as there are several hundred euros. Before this monumental price range, you have to refer to the criteria that are important to you and to compare the different brands.
